MPC852TVR100

Overview

The MPC852TVR100 is a PowerQUICC integrated communications controller based on the MPC8xx core. It operates at up to 100 MHz with a 66 MHz external bus, utilizing a 1.8 V core and 3.3 V I/O voltage. The device features a 32-bit architecture with 4-Kbyte instruction and data caches, an MMU with a 32-entry TLB, and a Communications Processor Module (CPM). Key peripherals include a Fast Ethernet Controller (FEC), PCMCIA interface, dual serial communication controllers (SCCs), and a serial management channel (SMC).

Feature Summary

• Integrated MPC8xx processor core with hardware memory management units and cache coherency.
• Dedicated Communications Processor Module (CPM) for offloading serial protocol processing.
• Built-in Fast Ethernet Controller supporting 10/100 Mbps operations.
• Supports PCMCIA master interface and multiple serial communication channels.

Applications

• Ethernet routers and hubs
• VoIP clients
• WiFi access points
• Customer Premises Equipment (CPE)

Procurement Notes

Verify the specific suffix VR100 against the manufacturer's current ordering guide to confirm package type and temperature range. Confirm that the component meets the required RoHS compliance standards for your target market. Ensure the datasheet revision matches the design requirements for electrical characteristics and timing specifications.

Selection Notes

Select this component when a low-pin-count solution is required for basic Ethernet connectivity and serial control. It is suitable for applications where high-throughput packet processing is not the primary constraint. Consider the limited cache size and lack of advanced security engines compared to newer generations.

Part Context

This part belongs to the Freescale PowerQUICC family, specifically derived from the MPC860 Quad Integrated Communications Controller. It represents a subset of the broader MPC8xx series, focusing on essential communication interfaces rather than high-end networking performance found in later PowerQUICC III models.

Replacement Considerations

NXP recommends using T1040, T1042, T4080, LS1026, or LS2044 families for new designs as the MPC852T is no longer recommended for new designs.

FAQ
