MPC850 PowerQUICC™ Integrated Communications Processor Hardware Specifications, Rev. 2

Freescale Semiconductor

Electrical and Thermal Characteristics

— Separate power supply input to operate internal logic at 2.2 V when operating at or below

25 MHz

— Can be dynamically shifted between high frequency (3.3 V internal) and low frequency (2.2 V

internal) operation

•

Debug interface

— Eight comparators: four operate on instruction address, two operate on data address, and two

operate on data

— The MPC850 can compare using the =,

≠, <, and > conditions to generate watchpoints

— Each watchpoint can generate a breakpoint internally

•

3.3-V operation with 5-V TTL compatibility on all general purpose I/O pins.

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.

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). Table 3 provides

the package thermal characteristics for the MPC850.

Input voltage 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).

Junction temperature 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.
