MPC852TCVR66A

Overview

The MPC852TCVR66A is a PowerQUICC III derivative processor based on the MPC8xx core, operating at up to 100 MHz with a 66 MHz external bus. It features a 32-bit architecture with 4-Kbyte instruction and data caches, MMUs, and an integrated Communications Processor Module (CPM). The device supports Fast Ethernet, PCMCIA, and multiple serial interfaces. It utilizes a 1.8 V core voltage and 3.3 V I/O operation with 5-V TTL compatibility.

Feature Summary

• Integrated MPC8xx core with embedded memory management units and dual 4-Kbyte caches
• Communications Processor Module (CPM) providing flexible serial communication capabilities
• Fast Ethernet Controller (FEC) supporting 10-Mbps operations
• PCMCIA interface compliant with release 2.1 standards

Applications

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

Procurement Notes

Verify the specific suffix 'CVR66A' against official NXP documentation to confirm frequency and package details. Ensure power supply sequencing adheres to the requirement that VDDL does not exceed VDDH during reset. 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 high integration of communications controllers within a single chip. It is suitable for designs needing robust Ethernet control and flexible serial peripheral support. Consider the 1.8 V core and 3.3 V I/O requirements when designing the power delivery network. Evaluate the thermal characteristics if operating in extended temperature ranges or high-load scenarios.

Part Context

The MPC852T belongs to the PowerQUICC III family, derived from the MPC860 Quad Integrated Communications Controller. It is designed for controller applications, particularly excelling in Ethernet control tasks. The processor combines a PowerPC architecture-based CPU with system integration and communication modules on a single die.

Replacement Considerations

Consult NXP documentation for direct substitutes within the MPC85xx series. Verify pinout and feature compatibility before replacing.
