The MPC850, which includes support for Ethernet, is specifically designed for cost-sensitive, remote-access, and telecommunications applications. It is provides functions similar to the MPC860, with system enhancements such as universal serial bus (USB) support and a larger (8-Kbyte) dual-port RAM. In addition to a high-performance embedded MPC8xx core, the MPC850 integrates system functions, such as a versatile memory controller and a communications processor module (CPM) that incorporates a specialized, independent RISC communications processor (referred to as the CP). This separate processor off-loads peripheral tasks from the embedded MPC8xx core. © Freescale Semiconductor, Inc., 2005. All rights reserved. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.

Electrical and Thermal Characteristics This section provides the AC and DC electrical specifications and thermal characteristics for the MPC850. Table 2 provides the maximum ratings. Table 2. Maximum Ratings (GND = 0V) Rating Supply voltage Symbol Value Unit VDDH -0.3 to 4.0 V VDDL -0.3 to 4.0 V KAPWR -0.3 to 4.0 V VDDSYN -0.3 to 4.0 V Input voltage 1 Vin GND-0.3 to VDDH + 2.5 V V Junction temperature 2 Tj 0 to 95 (standard) -40 to 95 (extended) °C Storage temperature range Tstg -55 to +150 °C 1 Functional operating conditions are provided with the DC electrical specifications in Table 5. Absolute maximum ratings are stress ratings only; functional operation at the maxima is not guaranteed. Stress beyond those listed may affect device reliability or cause permanent damage to the device. CAUTION: All inputs that tolerate 5 V cannot be more than 2.5 V greater than the supply voltage. This restriction applies to power-up and normal operation (that is, if the MPC850 is unpowered, voltage greater than 2.5 V must not be applied to its inputs). 2 The MPC850, a high-frequency device in a BGA package, does not provide a guaranteed maximum ambient temperature. Only maximum junction temperature is guaranteed. It is the responsibility of the user to consider power dissipation and thermal management. Junction temperature ratings are the same regardless of frequency rating of the device. This device contains circuitry protecting against damage due to high-static voltage or electrical fields; however, it is advised that normal precautions be taken to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (for example, either GND or VCC).

Due to the nature of the Clkout output buffer, IOH and IOL for Clkout should be extracted from the IBIS model at any output voltage level. 5 Power Considerations The average chip-junction temperature, TJ, in °C can be obtained from the equation: TJ = TA + (PD • θJA)(1) where TA = Ambient temperature, °C MPC850 PowerQUICC™ Integrated Communications Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 9 Bus Signal Timing θJA = Package thermal resistance, junction to ambient, °C/W PD = PINT + PI/O PINT = IDD x VDD, watts—chip internal power PI/O = Power dissipation on input and output pins—user determined For most applications PI/O < 0.3 • PINT and can be neglected. If PI/O is neglected, an approximate relationship between PD and TJ is: PD = K ÷ (TJ + 273°C)(2) Solving equations (1) and (2) for K gives: 2 K = PD • (TA + 273°C) + θJA • PD (3) where K is a constant pertaining to the particular part. K can be determined from equation (3) by measuring PD (at equilibrium) for a known TA. Using this value of K, the values of PD and TJ can be obtained by solving equations (1) and (2) iteratively for any value of TA. 5.1 Layout Practices Each VCC pin on the MPC850 should be provided with a low-impedance path to the board’s supply. Each GND pin should likewise be provided with a low-impedance path to ground. The power supply pins drive distinct groups of logic on chip. The VCC power supply should be bypassed to ground using at least four 0.1 µF by-pass capacitors located as close as possible to the four sides of the package. The capacitor leads and associated printed circuit traces connecting to chip VCC 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 VCC and GND planes. All output pins on the MPC850 have fast rise and fall times. Printed circuit (PC) 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 PC trace lengths of six inches are recommended. Capacitance calculations should consider all device loads as well as parasitic capacitances due to the PC 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 VCC 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. 6 Bus Signal Timing Table 6 provides the bus operation timing for the MPC850 at 50 MHz, 66 MHz, and 80 MHz. Timing information for other bus speeds can be interpolated by equation using the MPC850 Electrical Specifications Spreadsheet found at http://www.mot.com/netcomm. The maximum bus speed supported by the MPC850 is 50 MHz. Higher-speed parts must be operated in half-speed bus mode (for example, an MPC850 used at 66 MHz must be configured for a 33 MHz bus). The timing for the MPC850 bus shown assumes a 50-pF load. This timing can be derated by 1 ns per 10 pF. Derating calculations can also be performed using the MPC850 Electrical Specifications Spreadsheet.

For frequencies not marked on the part, new bus timing must be calculated for all frequency-dependent AC parameters. Frequency-dependent AC parameters are those with an entry in the FFactor column. AC parameters without an FFactor entry do not need to be calculated and can be taken directly from the frequency column corresponding to the frequency marked on the part. The following equations should be used in these calculations. For a frequency F, the following equations should be applied to each one of the above parameters: For minima: FFACTOR x 1000 (D50 - 20 x FFACTOR) D= + F For maxima: FFACTOR x 1000 (D50 -20 x FFACTOR) D= + F 1ns(CAP LOAD - 50) / 10 + where: D is the parameter value to the frequency required in ns F is the operation frequency in MHz D50 is the parameter value defined for 50 MHz CAP LOAD is the capacitance load on the signal in question. FFACTOR is the one defined for each of the parameters in the table. 2 Phase and frequency jitter performance results are valid only if the input jitter is less than the prescribed value. 3 If the rate of change of the frequency of EXTAL is slow (i.e. it does not jump between the minimum and maximum values in one cycle) or the frequency of the jitter is fast (i.e., it does not stay at an extreme value for a long time) then the maximum allowed jitter on EXTAL can be up to 2%. 4 The timing for BR output is relevant when the MPC850 is selected to work with external bus arbiter. The timing for BG output is relevant when the MPC850 is selected to work with internal bus arbiter. 5 The setup times required for TA, TEA, and BI are relevant only when they are supplied by an external device (and not when the memory controller or the PCMCIA interface drives them). 6 The timing required for BR input is relevant when the MPC850 is selected to work with the internal bus arbiter. The timing for BG input is relevant when the MPC850 is selected to work with the external bus arbiter. 7 The D[0–31] and DP[0–3] input timings B20 and B21 refer to the rising edge of the CLKOUT in which the TA input signal is asserted. 8 The D[0:31] and DP[0:3] input timings B20 and B21 refer to the falling edge of CLKOUT. This timing is valid only for read accesses controlled by chip-selects controlled by the UPM in the memory controller, for data beats where DLT3 = 1 in the UPM RAM words. (This is only the case where data is latched on the falling edge of CLKOUT. 9 The timing B30 refers to CS when ACS = '00' and to WE[0:3] when CSNT = '0'. 10 The signal UPWAIT is considered asynchronous to CLKOUT and synchronized internally. The timings specified in B37 and B38 are specified to enable the freeze of the UPM output signals. 11 The AS signal is considered asynchronous to CLKOUT.
