SLG46537_ds_108 page 52 of 192 SLG46537 8.3 connection matrix virtual inputs as mentioned previously, the conn ection matrix inputs come from the outputs of various digital m acrocells on the device. eight of the connection matrix inputs have the special characteristic that the state of these signal lines comes from a correspondin g data bit written as a register value via i 2 c. this gives the user the ability to write data via the serial channel, and have this information translated into sig nals that can be driven into the connection matrix and from the connection matrix to the digita l inputs of other macrocell s on the device. the i 2 c address for reading and writing these regist er values is at b yte 0244. six of the eight connection matr ix virtual inputs are dedicated to this virtual input function. an i 2 c write command to these register bits will set the signal values going into the connection matri x to the desired state. a read command to these register bits w ill read either the original data values coming from the nvm memory bits (that were loaded during the initial device startup), or the v alues from a previous write command (if that has happened). two of the eight connection matrix virtual inputs are shared wi th pin digital inputs,(io6 digital or i2c_virtual_0 input) and (io7 digital or i2c_virtual_1 input). if the virtual input mode is s elected, an i 2 c write command to these register bits will set the signal values going into the connection matrix to the desired state. t wo register bits select whether the connection matrix input com es from the pin input or fr om the virtual register: ? reg <1074> select scl & v irtual input 0 or io6 ? reg <1082> select sda & virtual input 1 or io7 see table below for connecti on matrix virtual inputs. 8.4 connection matrix virtual outputs the digital outputs of the various macrocells are routed to the connection matrix to enable interconnections to the inputs of other macrocells in the device. at the same time, it is possible to r ead the state of each of the macrocell outputs as a register va lue via i 2 c. this option, called connecti on matrix virtual outputs, allow s the user to remotely read the values of each macrocell output . the i 2 c addresses for reading these register values are at bytes 0240 to 0247. write commands to these same register values will be ignored (with the exception of the virtual input regist er bits at byte 0244). matrix input number matrix input signal function register bit addresses (d) 32 i2c_virtual_0 input reg<1952> 33 i2c_virtual_1 input reg<1953> 34 i2c_virtual_2 input reg<1954> 35 i2c_virtual_3 input reg<1955> 36 i2c_virtual_4 input reg<1956> 37 i2c_virtual_5 input reg<1957> 38 i2c_virtual_6 input reg<1958> 39 i2c_virtual_7 input reg<1959>
SLG46537_ds_108 page 53 of 192 SLG46537 9.0 combination function macrocells the SLG46537 has seventeen combination function macrocells that can serve more than one logic or timing function. in each case, they can serve as a look up table (lut), or as another lo gic or timing function. see the list below for the functions th at can be implemented in these macrocells: ? three macrocells that can serve as either 2-bit luts or as d f lip flops; ? five macrocells that can serve as either 3-bit luts or as d fl ip flops with se t/reset input; ? one macrocell that can serve as either 3-bit lut or as pipe de lay; ? one macrocell that can serve as either 2-bit lut or as program mable pattern generator (pgen); ? five macrocells that can serve as either 3-bit luts or as 8-bi t counter / delays; ? two macrocells that can serve as either 4-bit luts or as 16-bi t counter / delays. inputs/outputs for the 17 combi nation function macrocells are c onfigured from the connection matrix with specific logic functi ons being defined by the state of nvm bits. when used as a lut to implement combinatorial logic functions, the outputs of the luts can be configured to any user defined function, including th e following standard digital logic device s (and, nand, or, nor, xor, xnor). 9.1 2-bit lut or d flip flop macrocells there are three macrocells that c an serve as either 2-bit luts or as d flip flops. when used to implement lut functions, the 2-bit luts each take in two input signals from the connection m atrix and produce a single output, which goes back into the connection matrix. when used to implement d flip flop function, the two input signals from the connection matrix go to the dat a (d) and clock (clk) inputs for t he flip flop, with the output g oing back to the connection matrix. the operation of the d flip-flop and latch will follow the func tional descriptions below: ? dff: clk is rising edge trigger ed, then q = d; otherwise q wil l not change ? latch: when clk is low, then q = d; otherwise q remains its pr evious value (input d has no effect on the output, when clk is high). figure 10. 2-bit lut0 or dff0 dff0 clk d 2-bit lut0 out in0 in1 to connection matrix input <8> 4-bits nvm from connection matrix output <61> 1-bit nvm reg <1207:1204> reg <1191> from connection matrix output <60> q/nq reg <1207> dff or latch select reg <1206> output select (q or nq) reg <1205> dff initial polarity select lut truth table dff registers s0 s1 s0 s1 s0 s1 0: 2-bit lut0 in0 1: dff0 clk 0: 2-bit lut0 in1 1: dff0 data 0: 2-bit lut0 out 1: dff0 out

SLG46537_ds_108 page 82 of 192 SLG46537 9.7 4-bit lut or 16-bit counter / delay macrocells there are two macrocells that can serve as either 4-bit luts or as 16-bit counter / delays. when used to implement lut functio n, the 4-bit lut takes in four input signals from the connection m atrix and produces a single output, which goes back into the connection matrix. when used to implement 16-bit counter / dela y function, four input signals fr om the connection matrix go to the external clock (ext_clk) and reset (dly_in/cnt_reset), keep and up for the counter/delay, with the output going back to th e connection matrix. these two macrocells have an optional finite state machine (fsm ) function. there are two ma trix inputs for up and keep to support fsm functionality. any counter within green pak is coun ting down by default. in fsm mode (cnt/dly0 and cnt/dly1) it is possible to reverse counting by applying high level to up input. also, there is a possibility to pause counting by apply ing high level to keep input, after the level goes low, the counter will proceed counting.these macrocel ls can also operate in a one-sh ot mode, which will generat e an output pulse of user-defined width . these macrocells can also opera te in a frequency detection. delay time and output period c an be calculated us ing the follow ing formulas: ? delay time: [(counter data + 2) / clk in put frequency C offset *]; ? output period: [(count er data + 1) / clk i nput frequency C off set*]. one shot pulse width can be calculated us ing formula: ? pulse width = [(counter data + 2) / clk input frequency C offs et*]; *offset is the asynchronous time offset between the input signa l and the first clock pulse. for timing diagrams refer to section 9.8 cnt/dly/fsm timing diagrams. both of these macrocells can hav e their active count value read via i 2 c. see section 19.5.1.2 reading counter data via i2c for further details.

SLG46537_ds_108 page 97 of 192 SLG46537 9.10 wake and sleep controller (ws) the SLG46537 has a wake and sleep function for all acmps. the m acrocell cnt/dly0 can be reconfigured for this purpose reg<1319:1318>=11 and reg<1495>=1. the ws serves for power savi ng, it allows to switch on and off selected acmps on selected bit of 16-bit counter. to use any acmp under ws controller the following settings must be done: ? acmp power up input f rom matrix = 1 (for each acmp separately) ; ? cnt/dly0 must be set to wake an d sleep controller function (fo r all acmps); ? register ws => enable (for each acmp separately); ? cnt/dly0 set/reset inpu t = 0 (for all acmps); ? in case of using osc1 (25 mhz), osc0 must be set to force powe r on. as the osc any oscillator with any pre divider can be used. the user can select a period of time while the acmps are sleeping in a range of 1 - 65535 clock cycles. before they are sent to s leep their outputs are latched so the acmps remain their state (high or low) while sleeping. ws controller has the following settings: ? wake and sleep output state (high/low) if osc is powered off (power down option is selected; power dow n input = 1) and wake and sleep output state = high, the acmp is continuously on. figure 49. ws controller osc ck_osc ws_pd 000:/1 001:/4 010:/12 011:/24 100:/64 cnt_end ws out ws_pd power control from connection matrix output<58> analog control block reg<1316:1314> ws_pd to w&s out state selection block ws clock freq. selection reg<1591:1576> ws ratio control data reg<1494> ws out state for osc off acmps_pdb ws out bg/regulator pdb ws time selection reg<1489> acmp0..3 out to connection matrix input <60:57> from connection matrix output <54:51> reg<1493:1490> acmp ws enable ws out latchs note: ws_pd is high at ws osc (25 khz/2mhz osc) power down ws controller cnt0 out to connection matrix input <22> ck cnt 4 4 4 acmps_pdb + - ws
SLG46537_ds_108 page 98 of 192 SLG46537 if osc is powered off (power down option is selected; power dow n input = 1) and wake and sleep output state = low, the acmp is continuously off. both cases ws functi on is turned off. ? counter data (range: 0 - 65535) user can select wake and sleep ra tio of the acmp; counter data = sleep time, one clock = wake time. ? q mode - defines the state of ws counter data when set/reset s ignal appears reset - when active signal appears, the ws counter will reset t o zero and high level signal on its output will turn the acmps on. when reset signal goes out, t he ws counter will go low and turn the acmps off until the c ounter counts up to the end set - when active signal appear s, the ws count er will stop and low level signal on it s output will turn the acmps off. when set signal goes out, the ws counter will go on counting and hig h level signal will turn the acmps on while counter is counting up to the end. ? edge select defines the edge for q mode high level set/reset - switches mode set/reset when level is hi gh note: q mode operates only in ca se of "high le vel set/reset?. ? wake time selection - time re quired for wake signal to turn th e acmps on normal wake time - when ws signal is high, it takes a bg time ( 100/550 s) to turn the acmps on they will stay on until ws signal is low again. wake time is one clock period. it shoul d be longer than bg turn on time and minimal required comparing time of the acmp. short wake time - when ws signal is high, it takes a bg time (1 00/550 s) to turn the acmps on. they will stay on for 1 s and turn off regardless of ws si gnal. the ws signal width does not matter. ? keep - pauses counting while keep = 1 ? up - reverses counting if up = 1, cnt is counting up fr om user selected value to 65535 . if up = 0, cnt is c ounting down from user selected value to 0.

SLG46537_ds_108 page 100 of 192 SLG46537 10.0 analog comparators (acmp) there are four analog comparator (acmp) macrocells in the slg46 537. in order for the acmp ce lls to be used in a greenpak design, the power up signals (acmpx_pdb) need to be active. by connecting to signals coming fr om the connection matrix, it is possible to have each acmp be always on, always off, or power c ycled based on a digital signal coming from the connection matrix. also, all acmps have wake and sleep function (ws), see section 9.10 wake and sleep controller (ws) . when acmp is powered down, output is low. pwr up = 1 => acmp is powered up. pwr up = 0 => acmp is powered down. during acmp power up, its output will remain low, and then beco mes valid 1.03 ms (max) after acmp power up signal goes high, see figure 51 . if vdd is greater or equal to 2.7 v, it is possible to decrea se turn-on time by setting the bg ok delay to 100 s, see figure 52 . the acmp cells have an input "low bandwidth" signal selection , which can be used to save power and reduce noise impact when lower bandwid th signals are being compared. t o ensure proper chip startup operation, it is recommended to enable the acmps with the por s ignal, and not t he vdd signal. note: regulator and charge pump set to automatic on/off . figure 50. maximum power on delay vs. vdd, bg = auto-delay. 120 140 160 180 200 220 240 1.71 1.8 2.5 2.7 3 3.3 3.6 4.2 4.5 5 5.5 power on delay (s) vdd (v) -40?c +25?c +85?c
SLG46537_ds_108 page 101 of 192 SLG46537 each of the acmp cells has a positive input signal that can be provided by a variety of external sources. there is also a sele ctable gain stage (1x, 0.5x, 0.33x, 0.2 5x) before connec tion to the an alog comparator. the gain divider is unbuffered and consists of 250 k (typ.) resistors, see table 93 . for gain divider accuracy refer to table 94 . in- voltage range: 0 - 1.2 v. can use vref selection vdd/4 and vdd/3 to maintain this input range. input bias current < 1 na (typ). figure 51. maximum power on delay vs. vdd, bg = 550 s. 600 650 700 750 800 850 900 950 1000 1050 1100 1.71 1.8 2.5 2.7 3 3.3 3.6 4.2 4.5 5 5.5 power on delay (s) vdd (v) -40?c +25?c +85?c figure 52. maximum powe r on delay vs. vdd, bg = 100 s. 120 130 140 150 160 170 180 190 200 210 220 1.71 1.8 2.5 2.7 3 3.3 3.6 4.2 4.5 5 5.5 power on delay (s) vdd (v) -40?c +25?c +85?c
SLG46537_ds_108 page 102 of 192 SLG46537 each cell also has a hysteresis selection, to offer hysteresis of 0 mv, 25 mv, 50 mv or 200 mv. the 50 mv and 200 mv hysteresi s options can be used with internal voltage reference only, while 25 mv hysteresis option can be used with both internal and ext ernal voltage reference. the 50 mv and 200 mv hysteresis options are one way hysteresis. it means t hat the actual thresholds will be vref (high threshold) and vref - hysteresis (low threshold). th e acmp output will retain its previous value, if the input volt age is within threshold window (between vref and vref - hysteresis). p lease note: for the 25 mv hysteresis option threshold levels wi ll be vref + hysteresis/2 (high th reshold) and vref C hysteresis/2 (low threshold). note: any acmp powered on enables the bandgap internal circuit as well. an analog voltage will appear on vref even when the force bandgap option is set as disabled. for high input impedance when using the gain divider (x0.25, x0 .33, x0.5), it is possible to use the input buffer. however, th is will add some offset, see figure 53 to figure 54. it is not recommended to use acmp buffer wh en vdd < 2.5 v. table 93. gain divider input resistance gain x1 x0.5 x0.33 x0.25 input resistance 100 m 1 m 0.75 m 1 m table 94. gain di vider accuracy gain x0.5 x0.33 x0.25 accuracy 0.51% 0.34% 0.25% figure 53. typical buffer input voltage offset vs. voltage refer ence at t = (-40.... +85)c, buffer bandwidth = 1 khz, vhys = 0 mv, gain = 1. -40 -30 -20 -10 0 10 20 30 40 50 250 600 850 1200 voffset (mv) voltage reference (mv) upper limit @ vdd2.7v lower limit @ vdd2.7v

SLG46537_ds_108 page 121 of 192 SLG46537 15.0 rc oscillator (rc osc) the SLG46537 has three internal o scillators. rc oscillator that runs at 25 khz / 2 mhz (osc0), oscillator that runs at 25 mhz (osc1) and crystal oscillator. it is possible to use all three oscillators simultaneously. the fundamental frequency can also come from clock input (io15 or io17 fo r 25 khz / 2 mhz and io14 for 25 mhz or crystal osc), see section 21.0 external clocking . 15.1 25 khz/2 mhz and 25 mhz rc oscillators there are two divider stages that allow the user flexibility fo r introducing clock signals on various connection matrix input lines. the predivider allows the selection of /1, /2, /4 or /8 divide down frequency from the fundamental. the second stage divider ( only for 25 khz / 2 mhz oscillator) has an input of frequency from t he predivider, and outputs one of seven different frequencies o n connection matrix input lines <27> (out0) and <28> (out1). see figure 66 and figure 67 below for details. there are two modes of the power control pin, (reg<1658> for 25 khz / 2 mhz osc and reg<1657> for 25 mhz osc): ? power down <0> . if pwr control input of oscillator is low, the oscillator wil l be turned on. if pwr control input of oscillator is high the oscill ator will be turne d off and osc divider will reset. ? force on <1> . if pwr control input of oscilla tor is high, the oscillator wi ll be turned on. if pwr control input of oscillator is low the osci llator will be turned off. the pwr control signal has the highest priority. the SLG46537 has a 25 khz / 2 mhz osc fast start-up function re g<1338> (1 C on, 0 C off). it allows the osc to run immediately after power-up this decreases the settling time. no te that when osc fast start-up is on, the current consumption will rise. the user can select two osc powe r modes (reg<1343 for 25 khz / 2 mhz osc and reg<1341> for 25 mhz osc): ?if auto power on <0> is selected, the osc will run when any macrocell that uses osc is powered on. ?if force power on <1> is selected, the osc will run when the sl g46537 is powered on. osc can be turned on by: ? register control (force power on) ? delay mode, when delay requires osc ? cnt/fsm

SLG46537_ds_108 page 128 of 192 SLG46537 17.0 power on reset (por) the SLG46537 has a power-on reset (por) macrocell to ensure cor rect device initialization and operation of all macrocells in the device. the purpose of the por circuit is to have consisten t behavior and predictable results when the vdd power is first ramping to the device, and also while the vdd is falling during power-down. to accomplish this goal, the por drives a defined sequence of internal events that trigger changes to the states of different macrocells inside th e device, and finally to the s tate of the i/o pins. 17.1 general operation to start the por sequence in the SLG46537, the voltage applied on the vdd should be higher than the power_on threshold (see note 1). the full operationa l vdd range for the SLG46537 i s 1.71 v to 5.5 v (1.8 v 5% to 5 v10%). this means that the vdd voltage must ramp up to the operational voltage value, but the por sequence will start earlier, as soon as the vdd voltage rises to the power_on threshold. after the por sequence has sta rted, the SLG46537 will have a typical period of time to go through all the steps in the s equence (noted in the datasheet f or that device), and will be r eady and completely operational a fter the por sequence is complete. the SLG46537 is guaranteed to be powered down and nonoperationa l when the vdd voltage (voltage on vdd) is less than power off threshold (see in electrical characteristics table), but not less than -0.6 v. another essential condition for the c hip to be powered down is that no voltage higher (see note 2) than the vdd voltage is applied to any other pin. for example, if vdd voltage is 0.3 v, applying a voltage higher than 0.3 v to any o ther pin is incorrect, and can lead to incorrect or unexpected device behavior. note 1:the power_on threshold is defined in electrical characteristics table. note 2: there is a 0.6v margin due to forw ard drop voltage of t he esd protection diodes. to power down the chip the vdd voltage should be lower than the operational and to guarantee that chip is powered down it should be less than power off threshold. all pins are in high impedance st ate when the chip is powered d own and while the por sequence is taking place. the last step in the por sequence releases the i/o structures from the high i mpedance state, at which time the device is operational. the pi n configuration at this point in time is defined by the design pr ogrammed into the chip. also as it was mentioned before the vol tage on pins cant be bigger than t he vdd, this rule also applies to the case when the chip is powered on.
SLG46537_ds_108 page 129 of 192 SLG46537 17.2 por sequence the por system generat es a sequence of signa ls that enable cert ain macrocells. the sequence is shown in figure 77 . as can be seen from figure 77 after the vdd has start ramping up and crosses the power_on th reshold, first, the on-chip nvm memory is reset. next the chip reads the data from nvm, and tra nsfers this information to sram registers that serve to configu re each macrocell, and the connection matrix which routes signals between macrocells. the third stage causes the reset of the inp ut pins, and then to enable them. after that, the luts are reset a nd become active. after luts the delay cells, rc osc, dffs, latches and pipe delay are initialized. only after all macrocel ls are initialized internal por s ignal (por macrocell output) g oes from low to high. the last portion of the device to be initiali zed are the output pins, which t ransition from high impedance t o active at this point. the typical time that takes to complete the por sequence varies by device type in the greenpak family. it also depends on many environmental factors, such as: slew rate, vdd value, temperatu re and even will vary from chip to chip (process influence). figure 77. por sequence vdd por_nvm (reset for nvm) nvm_ready_out, i 2 c enable por_gpi (reset for input enable) por_lut (reset for lut output) por_core (reset for dly/rco/dff /latch/pipe dly) por_out (generate low to high to matrix) por_gpo asm enable (reset for output enable) t t t t t t t t input: ignore transition output: initial state (determined by reg<1354:1352>)

SLG46537_ds_108 page 138 of 192 SLG46537 18.4 basic asm timing the basic state transition timi ng from input on matrix connecti on output to output on matrix connection input is shown in figure 86 and figure 87 . the time from a valid input signal to the time that there is a valid change of state and valid signals being available on the state outputs is state machine output delay time (tst_ou t_delay). the minimum and maximum values of tst_out_delay define the differential timing between the shortest state trans ition (input on matrix output an d output on matrix input) and t he longest state transition (input on matrix output and output on matrix input). 18.5 asynchronous state machin es vs. synchronou s state machin es it is important to note that this macrocell is designed for asy nchronous operation, which means the following: 1. no clock source is needed, it reacts only to input signals. 2. the input signals do not have to be synchronized to each othe r, the macrocell will react to t he earliest valid signal for st ate transition. 3. this macrocell does not have traditional set-up and hold time specifications which are relat ed to incoming clock, as this macrocell has no clock source. 4. the macrocell only consumes p ower while in state transition. 18.6 asm power considerations a benefit of the asynchronous nat ure of this macrocell is that it will consume power only during state transitions. shown in figure 86 and figure 88 below, the current consumption of the macrocell will be a frac tion of a a between state transitions, and will rise only during state tran sitions. see section 5.7 idd estimator to find average current during state transitions. figure 86. state transition figure 87. state transition timing figure 88. state transition a state 0 state 1 input signal (a) tst_out_delay state outputs state 0 state 1 a state 0 state 1
SLG46537_ds_108 page 139 of 192 SLG46537 18.7 asm logical vs. physical design a successful design with the asm macrocell must include both th e logic level design as well as the physical level design. the gpak designer development software support user designs for the asm macrocell at both the logic level and physical level. the logic level design of the user defined state machine takes plac e inside the asm editor. in the asm editor, the user can select and name states, define and name allo wed state transitions, define the initial / reset state and define the output values for the 8 outputs in the output ram matri x. the physical level design tak es place in the general gpak designer window, and here the user makes connections for the sources for asm input signals, a s well as making connections f or destinations for asm output signals. 18.8 asm special case timing considerations 18.8.1 state transition pulse input timing all inputs to the asm macrocell are level sensitive. if the inp ut to the state machine macroce ll for a state transition is a p ulse, there is a minimum pulse width on the input to the state machin e macrocell (as measured at the matrix input to the macrocell) which is guaranteed to result in a state transition shown in figure 90 and figure 91 . this pulse width is defined by the state machine input pulse acceptance time (tst_pulse). if a pulse wid th that is shorter than tst_pulse is input to the state machine macrocell, it is indeterminate whether the state transition wil l happen or not. if a pulse that is rejected (invalid due to th e pulse width being narrower than the gu aranteed minimum of tst_pulse), this will not stop a valid pulse on another state transition i nput that does meet minimum pulse width. figure 89. state transition timing and power consumption figure 90. state transition figure 91. state transition pulse input timing input signal (a) tst_out_delay state outputs state 0 state 1 asm power consumption average active asm power sub ? a inactive asm power consumption a state 0 state 1 input signal (a) ts t _ p u l s e state outputs tst_pulse tst_out_delay state 0 state 1
SLG46537_ds_108 page 140 of 192 SLG46537 18.8.2 state transition competing input timing there will be situations where two input signals can be valid i nputs that will drive two different state transitions from a gi ven state. in that sense, the two signals are competing (signals a and b in figure 92 ), and the signal that arrives sooner should drive the state transition that will win, or drive the state transition . if one signal arrives tst_comp before the other one, it is gu aranteed to win, and the state transition that it codes for will be taken, as shown in figure 93 . if the two signals arrive within tst_comp of each other, it will be indeterminate which state transition will win , but one of the transitions will take place as long as the win ning signal satisfies the pulse width crite ria described in the paragraph a bove, as shown in figure 94 . figure 92. state transition - competing inputs figure 93. state transition timing - competing inputs indetermin ate figure 94. state transition timin g - competing inputs determinab le a state 0 state 2 state 1 b input signal (b) tst_out_delay state outputs state 0 state 1 or state 2 input signal (a) ts t _ c o m p input signal (b) tst_out_delay state outputs state 0 state 1 input signal (a) ts t _ c o m p
