MPC852TCVR50A

Overview

The MPC852TCVR50A is a PowerQUICC™ derivative of the MPC860 family, built on a 0.18-micron process. It features an embedded MPC8xx core operating up to 100 MHz with a maximum external bus frequency of 66 MHz. The device utilizes a 1.8-V core voltage and 3.3-V I/O operation, providing 5-V TTL compatibility for specific pins. It integrates a Fast Ethernet controller (FEC), a Communications Processor Module (CPM) with 8-Kbytes dual-port RAM, and a System Integration Unit (SIU).

Feature Summary

• Embedded MPC8xx processor core with MMUs and instruction/data caches.
• Integrated Communications Processor Module (CPM) supporting serial DMA channels.
• Fast Ethernet Controller (FEC) for 10/100 Mbps network connectivity.
• System Integration Unit (SIU) managing memory controllers and interrupts.

Applications

• Ethernet routers and hubs
• VoIP clients
• WiFi access points
• CPE equipment

Procurement Notes

Verify the complete part number against official NXP documentation to ensure correct speed grade and package configuration. Confirm that the ordering suffix matches the required thermal rating and pinout specifications. Cross-reference the datasheet revision history for any errata or updates relevant to the manufacturing lot.

Selection Notes

Select this component for applications requiring a dedicated communications controller with integrated Ethernet capabilities. Ensure the design supports the specified 1.8-V core and 3.3-V I/O power domains. Verify that the system architecture can accommodate the mandatory reset configurations defined in the hardware specification document.

Part Context
