MPC852TCVR100A

Overview

The MPC852TCVR100A is a microprocessor based on the PowerPC architecture, featuring an embedded MPC8xx core operating up to 100 MHz with a 66-MHz external bus. It utilizes a 1.8-V core voltage and 3.3-V I/O operation with 5-V TTL compatibility. The device integrates a Communications Processor Module (CPM) with 8-Kbytes of dual-port RAM, a Fast Ethernet Controller (FEC), and a System Integration Unit (SIU). Key interfaces include PCMCIA, SPI, UART, and two Serial Communication Controllers (SCCs).

Feature Summary

• Integrates a single-issue 32-bit MPC8xx core with instruction and data caches.
• Includes a Communications Processor Module (CPM) for serial communication management.
• Features a Fast Ethernet Controller (FEC) supporting 10-Mbps operations.
• Provides a PCMCIA interface compliant with release 2.1 specifications.

Applications

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

Procurement Notes

Verify the specific suffix 'CVR100A' against official NXP documentation to confirm package type, temperature range, and lead-free status. Confirm current availability as older MPC852T variants may be discontinued or subject to end-of-life notices. Ensure power sequencing requirements for VDDL and VDDH are met during procurement validation.

Selection Notes

Select this component for applications requiring integrated Ethernet control and serial communication processing within a compact footprint. Consider the 1.8-V core and 3.3-V I/O levels when designing power rails. Verify that the 100 MHz core speed and 66 MHz bus frequency meet system timing requirements. Evaluate thermal dissipation capabilities if operating in high-load scenarios.

Part Context

The MPC852T belongs to the PowerQUICC family, derived from the MPC860 Quad Integrated Communications Controller. It implements the embedded category of the Power Architecture technology. This family combines system-level support for industry-standard interfaces with processors designed for networking and telecommunications infrastructure applications.
