Procurement Notes

Verify the specific suffix 'D4' against official NXP documentation to confirm mask revision and temperature range details. Confirm that the component meets RoHS compliance requirements for your region. Check for obsolescence status as this part may be discontinued or recommended against new designs. Ensure supply chain sources are authorized distributors to avoid counterfeit parts.

Selection Notes

Select this processor for applications requiring high integration of communication protocols. Consider the CPM capabilities for handling complex serial data streams. Evaluate thermal management needs due to power dissipation characteristics. Compare cache sizes and peripheral counts with other MPC860 variants like the MPC860P or MPC860T if different memory or interface configurations are required.

Part Context

The MPC860 belongs to the PowerQUICC family of microprocessors designed by NXP Semiconductors (formerly Freescale). These processors are optimized for networking and communications control. The MPC860DTCVR66D4 is a specific variant within this family, offering a balance of processing power and communication peripherals suitable for embedded network nodes.

Replacement Considerations

Consult NXP's product transition notices for officially recommended replacements. Verify pinout and register compatibility before substituting with other MPC860 family members or newer architectures.
