MPC860TVR66D4

Microprocessors Overview

The MPC860TVR66D4 is a PowerQUICC microprocessor from NXP Semiconductors, built on the PowerPC core architecture. It features a single core with a 32-bit data bus width and operates at a maximum clock frequency of 66 MHz. The device utilizes a PBGA-357 package for surface mount installation. Internal memory includes a 4 kB instruction cache and a 4 kB data cache. It functions at a supply voltage of 3.3 V and supports an operating temperature range from 0°C to +95°C. Key interfaces include Ethernet, I2C, SPI, and UART.

Microprocessors Feature Summary

• Integrated Communications Processor Module (CPM) supporting multiple serial communication controllers and management channels
• Full static design capability allowing operation down to 0 MHz for flexible power management
• Supports dynamic bus sizing across 8, 16, and 32-bit configurations for optimized memory interfacing

Microprocessors Applications

• Network controller applications requiring integrated processing and peripheral solutions
• Communications systems utilizing Ethernet and serial interface protocols
• Industrial control environments demanding wide commercial temperature operation ranges

Microprocessors Procurement Notes

Verify component authenticity through authorized distribution channels due to legacy status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Ensure ESD handling procedures are strictly followed during assembly given the BGA package type. Validate that the 3.3V I/O voltage levels align with target system logic standards before integration.

Microprocessors Selection Notes

Select this variant when a 66 MHz clock speed is required within the commercial temperature range. The PBGA-357 package offers high pin count density suitable for complex peripheral integration. Consider the 4 kB cache configuration sufficient for specific firmware footprints compared to larger cache variants in the family.
