17 pc107a [preliminary] 2137c?hirel?03/04 thermal management information an estimation of the chip junction temperature, t j , can be obtained from the equation: t j = t a + (r ja p d ) where t a = ambient temperature for the package ( c) r ja = junction-to-ambient thermal resistance ( c/w) p d = power dissipation in the package (w) the junction-to-ambient thermal resistance is an industry-standard value that provides a quick and easy estimation of thermal performance. table 4 has four junction-to-ambient thermal resistances (r ja or r jma ). two test boards are used: single-signal-layer (1s) and four-layer boards with two internal planes (2s2p). which value is closer to the appli- cation depends on the system board thermal resistance and the density of other high- power dissipation components. to illustrate the process, determine the junction temperature based on the values pro- vided in table 4 for an pc107 that is mounted on a board with many internal planes using arbitrary values. if the pc107 is doing most of the power dissipation, use r jma of 26 c/w given in table 4. the ambient temperature near the device is 45 c. suppose the total typical power dissipation at 100 mhz core frequency is 2.1w (see table 6). the junction temperature is: t j = 45 + (2.1 26) = 100 c. if this value is less than the maximum junction temperature noted in table 2, the pc107 will not need a heat sink. if th e ambient temperature is hig her or the power dissipation is higher because of faster bus speed, th e device will probably need a heat sink. the pc107 may need a heat sink depending on the system. this section provides ther- mal management information for the flip chip plastic ball grid array (fc-pbga) package for air-cooled applications. proper thermal control design is primarily dependent on the system-level design?the heat sink, airflow, and thermal interface material. to reduce the die-junction temperature, heat sinks may be attached to the package by several meth- ods?spring clip to holes in the printed-circuit board or package, and mounting clip and screw assembly (see figure 7); however, due to the potential large mass of the heat sink, attachment through the printed-circuit board is suggested. the force of the heat sink on the die should not exceed 6 lb. the heat sink surface must be flat without protrusions and must be parallel with the die as the heat sink is brought into contact to avoid chipping the edges of the die and the heat sink. because of the small contact area of the heat sink, it is suggested that the mounting force be centered over the die.

42 pc107a [preliminary] 2137c?hirel?03/04 system design information pll power supply filtering the av dd and lav dd power signals are provided on the pc107a to provide power to the peripheral logic/memory bus pll and the sdram clock delay-locked loop (dll), respectively. to ensure stability of the in ternal clocks, the power supplied to the av dd and lav dd input signals should be filtered of any noise in the 500 khz to 10 mhz reso- nant frequency range of the plls. a separate circuit similar to the one shown in figure 30 using surface mount capacitors with minimum effective series inductance (esl) is recommended for each of the av dd and lav dd power signal pins. consistent with the recommendations of dr. howard johnson in high speed digital design: a handbook of black magic (prentice hall, 1993), multiple small capacitors of equal value are recom- mended over using multiple values. the circuits should be placed as close as poss ible to the respective input signal pins to minimize noise coupled from nearby circuits. routing directly as possible from the capacitors to the input signal pins with mini mal inductance of vias is important but pro- portionately less cr itical for the lav dd pin. figure 30. pll power supply filter circuit power supply voltage sequencing the notes in table 3 on page 12 contain c autions illustrated in figure 3 on page 13 about the sequencing of the external bus voltages and internal voltages of the pc107a. these cautions are necessary for the long term reliability of the part. if they are violated, the electrostatic discharge (esd) protection diodes will be forward biased and excessive current can flow through these diodes. figure 3 shows a typical ramping voltage sequence where the dc power sources (voltage regulators and/or power supplies) are connected as shown in figure 31. the volta ge regulator delay shown in figure 3 can be zero if the various dc voltage levels are all applied to the target board at the same time. the ramping voltage sequence shows a scenario in which the v dd /av dd /lav dd power plane is not loaded as much as the ov dd /gv dd power plane and thus v dd /av dd /lav dd ramps at a faster rate than ov dd /gv dd . if the system power supply design does not control the voltage sequencing, the circuit of figure 31 can be added to meet these requirements. the mur420 diodes of figure 31 control the maximum potential difference between the 3.3 bus and internal voltages on power-up and the 1n5820 schottky diodes regul ate the maximum potential difference on power-down. vdd avdd or lavdd 10 ? 2.2 f 2.2 f gnd low esl surface mount capacitors
43 pc107a [preliminary] 2137c?hirel?03/04 figure 31. example voltage sequencing circuits decoupling recommendations due to the pc107a?s dynamic power management feature, large address and data buses, and high operating frequencies, the pc107a can generate transient power surges and high frequency noise in its power supply, especially while driving large capacitive loads. this noise must be prevented from reaching other components in the pc107a system, and the pc107a itself requires a clean, tightly regulated source of power. therefore, it is recommended that the system designer plac e at least one decou- pling capacitor at each v dd , ov dd , gv dd , and lv dd pin of the pc107a. it is also recommended that these decoupling capacitors receive their power from separate v dd , ov dd , gv dd , and gnd power planes in the pcb, ut ilizing short traces to minimize induc- tance. these capacitors should have a value of 0.1 f. only ceramic smt (surface mount technology) capacitors should be used to minimize lead inductance, preferably 0508 or 0603, oriented such that connections are made along the length of the part. in addition, it is recommended that there be several bulk storage capacitors distributed around the pcb, feeding the v dd , ov dd , gv dd , bv dd , and lv dd planes, to enable quick recharging of the smaller chip capacitors. these bulk capacitors should have a low esr (equivalent series resistance ) rating to ensure the quick response time necessary. they should also be connected to the power and gr ound planes through two vias to minimize inductance. suggeste d bulk capacitors-100 ? 330 f (avx tps tantalum or sanyo oscon). connection recommendations to ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal level. unused active low inputs should be tied to ov dd . unused active high inputs should be connected to gnd. all nc (no-connect) signals must remain unconnected. power and ground connections must be made to all external v dd , ov dd , gv dd , lv dd , bv dd , and gnd pins of the pc107a. the pci_sync_out signal is intended to be routed halfway out to the pci devices and then returned to the pci_sync_in input of the pc107a. the sdram_sync_out signal is intended to be routed halfway out to the sdram devices and then returned to the sdram_sync_in input of the pc107a. the trace length may be used to skew or adjust the timing window as needed. see motorola appli- cation note "an1794/d" for more information on this topic. the trst signal must be asserted during reset to ensure proper initialization and oper- ation of the pc107a. it is recommended that the trst signal be connected to the system hreset signal or pulled down with a 100 ? - 1 k ? resistor. + 5v source + 3.3v source 5v 3.3v 3.3v mur420 mur420 in5820 in5820 2.5v 2.5v + 2.5v source
44 pc107a [preliminary] 2137c?hirel?03/04 pull-up/pull-down resistor requirements the data bus input receivers are normally turned off when no read operation is in progress; therefore, they do not require pull-up resistors on the bus. the processor data bus signals are: dh[0 ? 31], dl[0 ? 31], and par[0 ? 7]. the memory data bus signals are: mdh[0 ? 31], mdl[0 ? 31], and par/ar[0 ? 7]. if the 32-bit data bus mode is selected, the input receivers of the unused data and parity bits (dl[0 ? 31], dp[4 ? 7], mdl[0 ? 31], and par[4 ? 7]) will be disabled, and their outputs will drive logic zeros when they would otherwise normally be driven. for this mode, these pins do not require pull-up resistors, and should be left unconnected by the sys- tem to minimize possible output switching. it is recommended that artry , ta , and ts have weak pull-up resistors (2 k ? ? 10 k ? ) connected to bv dd . it is recommended that mtp[1 ? 2] and test2 have weak pull-up resistor (2 k ? ? 10 k ? ) connected to gv dd . it is recommended that the following signals be pulled up to ov dd with weak pull-up resistors (2 k ? ? 10 k ? ): sda, scl, test1 , and ftp[3 ? 3]. it is recommended that the following pci control signals be pulled up to lv dd with weak pull-up resistors (2 k ? ? 10 k ? ): devsel , frame , irdy , lock , perr , serr , stop , trdy and inta . the resistor values may need to be adjusted stronger to reduce induced noise on specific board designs. the following pins have internal pull-up resistors enabled at all times: req [06 ? 4], tck, tdi, tms, and trst , br1 , hreset_cpu , mcp , qack , sreset , test and trig_out . see table 1, ?pc107a pinout listing,? on page 5 for more information. the following pins have internal pull-up re sistors enabled only while device is in the reset state: mdl0, foe , rcs0 , sdras , sdcas , cke, sdbao, and sdma[10 ? 1]. see table 1, ?pc107a pinout listing,? on page 5 for more information. the following pins are reset configuration pins: mdl0, foe , rcs0 , sdbao, sdma[10 ? 1], and pll_cfg[0 ? 3]. these pins are sampled during reset to configure the device. any other unused active low input pins should be tied to a logic one level via weak pull- up resistors (2 k ? ? 10 k ? ) to the appropriate power supply listed in table 3 on page 12. unused active high input pins should be tied to gnd via weak pull-down resistors (2 k ? ? 10 k ? ).
