MPC852TVR50A

Overview

The MPC852TVR50A is a derivative of the MPC860 PowerQUICC family, featuring an embedded MPC8xx core operating up to 100 MHz with a 66-MHz external bus. It utilizes a 1.8-V core and 3.3-V I/O operation with 5-V TTL compatibility. The device integrates a Fast Ethernet controller (FEC), System Integration Unit (SIU), and Communications Processor Module (CPM) with 8-Kbytes of dual-port RAM.

Feature Summary

• Embedded MPC8xx core with MMUs and instruction/data caches
• Integrated Fast Ethernet controller supporting 10-Mbps operation
• Communications processor module with serial DMA channels
• PCMCIA interface compliant with release 2.1

Applications

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

Procurement Notes

Verify the specific suffix 'VR50A' against official NXP documentation to confirm frequency grade and package details. Ensure power supply sequencing adheres to the requirement that VDDL must not exceed VDDH during power-on reset or power down. Confirm thermal management strategies align with the specified junction-to-ambient resistance values for the target application environment.

Selection Notes

Select this component for applications requiring integrated communications control and Ethernet connectivity within a PowerPC architecture framework. Consider the 1.8-V core voltage requirements and the need for appropriate level shifting if interfacing with 5-V logic systems. Evaluate the available memory controllers and serial communication interfaces against system bandwidth needs.

Part Context

This part belongs to the MPC860 PowerQUICC family, designed as a versatile one-chip integrated microprocessor and peripheral combination. It serves as a subset of the Quad Integrated Communications Controller series, targeting controller applications that demand efficient data handling and network processing capabilities.

Replacement Considerations

Consult the MPC852T product summary page for published errata or updates. Verify functional compatibility with existing designs when considering alternative members of the MPC8xx or MPC860 families.
