MPC860DTVR50D4

Overview

The MPC860DTVR50D4 is a microprocessor from the NXP PowerQUICC family, built on the Power Architecture core. It features a single 32-bit core with a 4 KB instruction cache and 4 KB data cache. The device supports up to 50 MHz operation and includes an integrated Communications Processor Module (CPM). Connectivity options include Ethernet and ATM support via UTOPIA. It operates at 3.3 V and utilizes a 357-pin PBGA package.

Feature Summary

• Integrated Communications Processor Module (CPM) for offloading serial communication tasks
• Support for Ethernet and Asynchronous Transfer Mode (ATM) protocols
• Dynamic bus sizing capability for flexible memory interface configurations
• Comprehensive low-power modes including Doze, Sleep, and Deep Sleep

Applications

• Networking controller applications
• Communications systems requiring protocol processing
• Industrial control systems with serial interfaces

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm the specific revision level matches system requirements. Check for moisture sensitivity handling instructions prior to assembly. Ensure compatibility with existing PCB footprints and thermal management designs.

Selection Notes

Select this component when a dedicated communications processor is needed alongside a general-purpose CPU. The MPC860DT variant specifically offers two Serial Communication Controllers (SCCs) and ATM support. Evaluate power consumption profiles against available cooling solutions given the BGA package constraints.

Part Context

This part belongs to the MPC860 PowerQUICC family, which integrates a RISC processor with specialized communication peripherals. The 'DT' suffix indicates specific peripheral configurations compared to other family members like the MPC860T or MPC860P. The 'VR' suffix denotes the specific package type and temperature range.

Replacement Considerations

Direct replacements within the same family include MPC860TVR50D4 or MPC860ENVR50D4R2, depending on required peripheral counts such as SCCs and ATM support.
