6 (ae2.0e) mb82dbs04163c -70l preliminary  functional description this device supports asynchronous page read & normal write operation and synchronous burst read & burst write operation for faster memory access and features three kinds of power down modes for power saving as user configurable option. power-up it is required to follow the power-up timing to start executing proper device operation. refer to power-up timing. after power-up, the device defaults to asynchronous page read & normal write operation mode with sleep power down feature. configuration register the configuration register (cr) is used to configure the type of device function among optional features. each selection of features is set through cr set sequence after power-up. if cr set sequence is not performed after power-up, the device is configured for asynchr onous operation with sleep power down feature as default configuration cr set sequence the cr set requires total 6 read/write operations with unique address. between each read/write operation requires that device being in standby mode. following table shows the detail sequence. the first cycle is to read from most significant address (msb). the second and third cycle are to write to msb. if the se cond or third cycle is writt en into the different address, the cr set is cancelled. and the data written by the second or third cycle is valid as a normal write operation. it is recommended to write back the data (rda) read by first cycle to msb in order to secure the data. the forth and fifth cycle is to write to msb. the data of forth and fifth cycle is don?t-care. if the forth or fifth cycle is written into different address, the cr set is also cancelled but write data may not be written as normal write operation. the last cycle is to read from specific address key for mode selection. and read data (rdb) is invalid. once this cr set sequence is performed from an initial cr set to the other new cr set, the written data stored in memory cell array may be lost. so, cr set sequence should be performed prior to regular read/write operation if necessary to change from default configuration. cycle # operation address data 1st read 3fffffh (msb) read data (rda) 2nd write 3fffffh rda 3rd write 3fffffh rda 4th write 3fffffh x 5th write 3fffffh x 6th read address key read data (rdb)

8 (ae2.0e) mb82dbs04163c -70l preliminary  functional description (continued) power down the power down is low power idle state controlled by ce2. ce2 low drives the device in power down mode and maintains low power idle state as long as ce2 is kept low. ce2 high resume the device from power down mode. this device has three power down modes, sleep, 8m partial, and 16m partial. the selection of power down mode is set through cr set sequence. each mode has following data retention features. the default state is sleep mode and it is the lowest power consumption but all data will be lost once ce2 is brought to low for power down. it is not required to perform cr set sequence to set to sleep mode after power- up in case of asynchronous operation. when rp=0, power down comprehends a function to reset the device to default configuration (asyncronous mode). after resuming from power down mode, the device is back in default configurations. this is effective only when ps is set on sleep mode. when partial mode is selected, rp=0 is not effective. mode data retention size retention address sleep [default] no n/a 8m partial 8m bit 000000h to 07ffffh 16m partial 16m bit 000000h to 0fffffh
9 (ae2.0e) mb82dbs04163c -70l preliminary  functional description (continued) burst read/write operation synchronous burst read/write operation provides faster memory access that synchronized to microcontroller or system bus frequency. configuration register set is requi red to perform burst read & write operation after power- up. once cr set sequence is performed to select synchronous burst mode, the device is configured to synchronous burst read/write operation mode with corresponding rl and bl that is set through cr set sequence together with operation mode. in order to perform sync hronous burst read & write operation, it is required to control new signals, clk, adv and wait that low power srams don?t have. address adv clk dq valid ce 1 oe wait high-z high-z rl bl q 2 q bl q 1 we high address adv clk dq valid ce 1 oe wait high-z high-z rl-1 bl d 2 d bl d 1 we high burst read operation burst write operation
10 (ae2.0e) mb82dbs04163c -70l preliminary  functional description (continued) clk input function the clk is input signal to synchronize memory to microcontroller or system bus frequency during synchronous burst read & write operation. the clk input increments device internal address counter and the valid edge of clk is referred for latency counts from address latch, burst write data latch, and burst read data out. during synchronous operation mode, clk input must be supplied except for standby state and power down state. clk is don?t care during asynchronous operation. adv input function the adv is input signal to indicate valid address presence on address inputs. it is applicable to synchronous operation as well as asynchronous operation. adv input is active during ce 1=l and ce 1=h disables adv input. all addresses are determined on the positive edge of adv . during synchronous burst read/write operation, adv =h disables all address inputs. once adv is brought to high after valid address latch, it is inhibited to bring adv low until the end of burst or until burst operation is terminated. adv low pulse is mandatory for synchronous burst read/write operation mode to latch the valid address input. during asynchronous operation, adv =h also disables all address inputs. adv can be tied to low during asynchronous operation and it is not necessary to control adv to high. wait output function the wait is output signal to indicate data bus status when the device is operating in synchronous burst mode. during burst read operation, wait output is enabled after specified time duration from oe =l or ce 1=l whichever occurs last. wait output low indicates data out at next clock cycle is invalid, and wait output becomes high one clock cycle prior to valid data out. during oe read suspend, wait output doesn?t indicate data bus status but carries the same level from previous clock cycle (kept high) except for burst read suspend on the final data output. if final read data out is suspended, wait output become high impedance after specified time duration from oe =h. during burst write operation, wait output is valid to high level after specified time duration from we =l or ce 1=l whichever occurs last and kept high for entire write cycles including we write suspend. the actual write data latching starts on the appropriate clock edge with respect to valid clock edge, read latency and burst length. during we write suspend, wait output doesn?t indicate data bus status but carries the same level from previous clock cycle (kept high) except for write suspend on the final data input. if final write data in is suspended, wait output become high impedance after specified time duration from we =h. this device doesn?t incur additional delay against crossing device-row boundary or internal refresh operation. therefore, the burst operation is always started after fixed latency with respect to read latency. and there is no waiting cycle asserted in the middle of burst operation except for burst read or write suspend by oe brought to high or we brought to high. thus, once wait output is enabled and brought to high, wait output keep high level until the end of burst or until the burst operation is terminated. when the device is operating in asynchronous mode, wait output is always in high impedance.
11 (ae2.0e) mb82dbs04163c -70l preliminary  functional description (continued) latency read latency (rl) is the number of clock cycles betw een the address being latched and first read data becoming available during synchronous burst read operation. it is set through cr set sequence after power-up. once specific rl is set through cr set sequence, write latency, that is the number of clock cycles between address being latched and first write data being latched, is automatically set to rl-1.the burst operation is always started after fixed latency with respect to read latency set in cr. address adv clk valid q1 q2 q3 d1 d2 d3 d4 0 12 345 rl=3 q4 d5 dq [out] dq [in] ce 1 oe or we wait wait 6 q5 d5 q1 q2 d1 d2 d3 rl=4 q3 d4 dq [out] dq [in] wait wait q4 d5 q1 d1 d2 rl=5 q2 d3 dq [out] dq [in] wait wait q3 d4 high-z high-z high-z high-z high-z high-z d1 rl=6 q1 d2 dq [out] dq [in] wait wait q2 d3 high-z high-z
12 (ae2.0e) mb82dbs04163c -70l preliminary  functional description (continued) address latch by adv the adv indicates valid address presence on address inputs. during synchronous burst read/write operation mode, all the address are determined on the positive edge of adv when ce 1=l. the specified minimum value of adv =l setup time and hold time against valid edge of clock where rl count begin must be satisfied for appropriate rl counts. valid address must be determined with specified setup time against either the negative edge of adv or negative edge of ce 1 whichever comes late. and the determined valid address must not be changed during adv =l period. burst length burst length is the number of word to be read or writ e during synchronous burst read/write operation as the result of a single address latch cycle. it can be set on 8, 16 words boundary or continuous for entire address through cr set sequence. the burst type is sequential that is incremental decoding scheme within a boundary address. starting from initial address being latched, device internal address counter assign +1 to the previous address until reaching the end of boundary address and then wrap round to least significant address (=0). after completing read data out or write data latch for the set burst length, operation automatically ended except for continuous burst length. when continuous burst length is set, read/write is endless unless it is terminated by the positive edge of ce 1. single write single write is synchronous write operation with burst length =1. the device can be configured either to "burst read & single write" or to "burst read & burst write" through cr set sequence. once the device is configured to "burst read & single write" mode, the burst length for synchronous write operation is always fixed 1 regardless of bl values set in cr, while burst length for read is in accordance with bl values set in cr. write control the device has two types of we signal control method, "we level control" and "we single clock pulse control", for synchronous write operation. it is configured through cr set sequence. address adv clk valid 0 12 345 ce 1 we 6 d1 d2 rl=5 d3 dq [in] wait d4 we d1 d2 d3 dq [in] wait d4 high-z t wld high-z t wsck t ckwh t wlth t wlth we level control we single clock pulse control t clth
13 (ae2.0e) mb82dbs04163c -70l preliminary  functional description (continued) burst read suspend burst read operation can be suspended by oe high pulse. during burst read operation, oe brought to high suspends burst read operation. once oe is brought to high with the specified set up time against clock where the data being suspended, the device internal counter is suspended, and the data output become high impedance after specified time duration. it is inhibited to suspend the first data out at the beginning of burst read. oe brought to low resumes burst read operation. once oe is brought to low, data output become valid after specified time duration, and internal address counter is reactivated. the last data out being suspended as the result of oe =h and first data out as the result of oe =l are from the same address. in order to guarantee to output last data before suspension and first data after resumption, the specified minimum value of oe =l hold time and setup time against clock edge must be satisfied respectively. burst write suspend burst write operation can be suspended by we high pulse. during burst write operation, we brought to high suspends burst write operation. once we is brought to high with the specified set up time against clock where the data being suspended, device internal counter is suspended, data input is ignored. it is inhibited to suspend the first data input at the beginning of burst write. we brought to low resumes burst write operation. once we is brought to low, data input become valid after specified time duration, and internal address counter is reactivated. the write address of the cycle where data being suspended and the first write address as the result of we =l are the same address. in order to guarantee to latch the last data input before suspension and first data input after resumption, the specified minimum value of we =l hold time and setup time against clock edge must be satisfied respectively. burst write suspend function is available when the device is operating in we level controlled burst write only. q 2 dq oe clk q 1 t ac t ckqx t olz t ac q 2 t ckqx t ac q 3 t ckqx t ac t ckoh t osck t ckoh t osck t ohz wait t cktv q 4 dq we d 1 t dhck t dsck t dsck d 2 t dhck t dsck t dsck d 3 t dhck t dsck t dsck t ckwh t wsck t ckwh t wsck d 2 d 4 wait high clk
