Microprocessors Procurement Notes

Verify the specific suffix 'ZQ' corresponds to the required package thickness and lead form factor against the mechanical data sheet. Confirm the operating temperature range meets system requirements, as standard variants typically cover 0°C to 95°C. Ensure compatibility with existing PCB footprints for the 357-pin BGA configuration before finalizing procurement.

Microprocessors Selection Notes

Select this component when a single-chip solution combining a PowerPC processor with extensive serial communication peripherals is required. Consider the 66 MHz clock speed and cache sizes relative to application processing demands. Evaluate the need for ATM or Ethernet support, noting that specific interface availability may vary within the MPC860 family subtypes.
