Procurement Notes

Verify the specific ordering suffix against official NXP documentation to confirm package type, speed grade, and temperature range. Confirm current manufacturing status as legacy components may be discontinued or subject to last-time buy restrictions. Ensure compatibility with existing board designs regarding pinout and voltage levels before procurement.

Selection Notes

Select this component for applications requiring a balance of processing performance and integrated communication peripherals. The dual-processor design offloads serial and imaging tasks from the main core. Evaluate memory requirements against the available glueless interfaces for DRAM, SRAM, and Flash. Consider the extensive power management features for battery-operated portable devices.

Part Context

The MPC823 belongs to the Motorola/Freescale/NXP PowerQUICC family of integrated communications processors. It was designed to provide a cost-effective entry point into the embedded PowerPC ecosystem for mobile and communication applications. The device represents a transition period where communication functions were increasingly integrated onto the same die as the central processing unit.

Replacement Considerations
