MPC852TVR100A

Overview

The MPC852TVR100A is a PowerQUICC processor 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 Fast Ethernet Controller (FEC), Communications Processor Module (CPM) with 8-Kbytes dual-port RAM, PCMCIA interface, and System Integration Unit (SIU).

Feature Summary

• Integrates a 32-bit RISC controller within the CPM supporting serial DMA channels and communication-specific commands.
• Includes a Fast Ethernet Controller for full 10-Mbps operation compliant with IEEE 802.3 standards.
• Features a PCMCIA master socket interface compliant with release 2.1 specifications.

Applications

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

Procurement Notes

Verify the specific suffix VR100A against official NXP documentation to confirm frequency and package details. Confirm RoHS compliance status as datasheets may vary by revision. Ensure power supply sequencing adheres to VDDL and VDDH constraints during procurement validation.

Selection Notes

Select this component for applications requiring integrated communications control and Ethernet connectivity. Evaluate thermal resistance requirements based on the expected junction-to-ambient conditions. Verify that the 1.8-V core and 3.3-V I/O levels match the system design constraints.

Part Context

This part belongs to the MPC860 PowerQUICC family derivatives. It shares architectural similarities with other MPC8xx processors but offers a specific subset of features optimized for controller applications. The device implements the PowerPC architecture with memory management units.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic replacements are not recommended due to specific timing and electrical characteristic differences within the PowerQUICC family.
