msc8101 technical data, rev. 16 freescale semiconductor 4-1 design considerations 4 this chapter includes design and layout guidelines for manufacturing boards using the msc8102. 4.1 thermal design considerations the average chip-junction temperature , t j , in c can be obtained from the following: t j = t a + (p d ? ja ) equation 1 where t a = ambient temperature c ja = package thermal resistance , junction to ambient , c/w p d = p int + p i/o in w p int = i dd v dd in w?chip internal power p i/o = power dissipation on output pins in w?user determined the user should set t a and p d such that t j does not exceed the maximum operating conditions. in case t j is too high, the user should either lower the ambient temperature or the power dissipation of the chip. 4.2 electrical design considerations the input voltage must not exceed the i/o supply v ddh by more than 2.5 v at any time, including during power-on reset. in turn, v ddh can exceed v dd / v ccsyn by more than 3.3 v during power-on reset, but for no more than 100 ms. v ddh should not exceed v dd / v ccsyn by more than 2.1 v during normal operation. v dd / v ccsyn must not exceed v ddh by more than 0.4 v at any time, including during power-on reset. therefore the recommendation is to use ?bootstrap? diodes between the power rails, as shown in figure 4-1 . figure 4-1. bootstrap diodes for power-up sequencing i/o power core/pll supply mur420 mur420 mur420 mur420 3.3 v (v ddh ) 1.6 v (v dd /v ccsyn )
msc8101 technical data, rev. 16 4-2 freescale semiconductor design considerations select the bootstrap diodes such that a nominal v dd /v ccsyn is sourced from the v ddh power supply until the v dd / v ccsyn power supply becomes active. in figure 4-1 , four mur420 schottky barrier diodes are connected in series; each has a forward voltage (v f ) of 0.6 v at high currents, so these diodes provide a 2.4 v drop, maintaining 0.9 v on the 1.6 v power line. once the core/pll power supply stabilizes at 1.6 v, the bootstrap diodes will be reverse biased with negligible leakage current. the v f should be effective at the current levels required by the processor. do not use diodes with a nominal v f that drops too low at high current. 4.3 power considerations the internal power dissipation consists of three components: p int = p core + p siu + p cpm power dissipation depends on the operating frequency of the different portions of the chip. table 2-5 provides typical power values at the specified operating frequencies. to determine the typical power dissipation for a given set of frequencies, use the following equations: p core (f) = ((p core ? p lco )/f core ) f corea + p lco p cpm (f) = ((p cpm ? p lcp )/f cpm ) f cpma + p lcp p siu (f) = ((p siu ? p lsi )/f siu ) f siua + p lsi where: f core is the core frequency, f siu is the siu frequency, and f cpm is the cpm frequency specified in ta b l e 2 -5 in mhz f corea is the actual core frequency, f siua is the actual siu frequency, and f cpma is the actual cpm fre- quency in mhz p lco , p lsi , and p lcp are the leakage power values specified in table 2-5 all power numbers are in mw power consumption is assumed to be linear with frequency. the first part of each equation computes a mw/mhz value that is then scaled based on the actual frequency used. to determine a total power dissipation in a specific application, you must add the power values derived from the above set of equations to the value derived for i/o power consumption using the following equation for each output pin: p = c v ddh 2 f 10 ?3 equation 2 where: p = power in mw, c = load capacitance in pf, f = output switching frequency in mhz. for an application in which external data memory is used in a 32-bit single bus mode and no other outputs are active, the core runs at 200 mhz, the cpm runs at 100 mhz and the siu runs at 50 mhz, power dissipation is calculated as follows: assumptions: external data memory is accessed every second cycle with 10% of address pins switching. external data memory writes occurs once every eight cycles with 50% of data pins switching. each address and data pin has a 30 pf total load at the pin. the application operates at v ddh = 3.3 v.
layout practices msc8101 technical data, rev. 16 freescale semiconductor 4-3 since the address pins switch once at every second cycle, the address pins frequency is a quarter of the bus frequency (that is, 25 mhz). for the same reason the data pins frequency is 3.125 mhz. calculating internal power (from ta b l e 2 -5 values): p core (200) = ((p core ? p lco )/300) 200 + p lco =((450 ? 3) / 300 200 + 3 = 301 p cpm (100) = ((p cpm ? p lcp ) / 200) 100 + p lcp = ((320 ? 6) / 200) 100 + 6 = 163 p siu (50) = ((p siu ? p lsi ) / 100) 50 + p lsi = ((80 ? 2) / 100) 50 + 2 = 41 p int = p core (200) + p cpm (100) + p siu (50) = 301 + 163 + 41 = 505 p d = p int + p i/o = 505 + 67 = 572 maximum allowed ambient temperature is: t a = t j ? (pd ja ) 4.4 layout practices each v cc and v dd pin on the msc8101 should be provided with a low-impedance path to the board?s power supply. similarly, each gnd pin should be provided with a low-impedance path to ground. the power supply pins drive distinct groups of logic on the chip. the v cc power supply should be bypassed to ground using at least four 0.1 f by-pass capacitors located as closely as possible to the four sides of the package. the capacitor leads and associated printed circuit traces connecting to chip v cc , v dd , and gnd should be kept to less than half an inch per capacitor lead. a four-layer board is recommended, employing two inner layers as v cc and gnd planes. all output pins on the msc8101 have fast rise and fall times. printed circuit board (pcb) trace interconnection length should be minimized in order to minimize undershoot and reflections caused by these fast output switching times. this recommendation particularly applies to the address and data busses. maximum pcb trace lengths of six inches are recommended. capacitance calculations should consider all device loads as well as parasitic capacitances due to the pcb traces. attention to proper pcb layout and bypassing becomes especially critical in systems with higher capacitive loads because these loads create higher transient currents in the v cc , v dd , and gnd circuits. pull up all unused inputs or signals that will be inputs during reset. special care should be taken to minimize the noise levels on the pll supply pins. there are 2 pairs of pll supply pins: v ccsyn - gnd syn and v ccsyn1 - gnd syn1 . each pair supplies one pll. to ensure internal clock stability, filter the power to the v ccsyn and v ccsyn1 inputs with a circuit similar to the one in figure 0-1. . to filter as much noise as possible, place the circuit as close as possible to v ccsyn and v ccsyn1 . the 0.01-f capacitor should be closest to v ccsyn and v ccsyn1 , followed by the 10-f capacitor, the 10-nh inductor, and finally the 10- ? resistor to v dd . these traces should be kept short and direct. table 4-1. power dissipation pins number of pins switching c v ddh 2 f 10 ?3 power in mw address data, hrd , hrw clkout 4 34 1 30 30 30 3.3 2 3.3 2 3.3 2 12.5 10 ?3 3. 125 10 ?3 50 10 ?3 16.25 34.75 16 total p i/o 67
