MPC860DPZQ66D4

Overview

The MPC860DPZQ66D4 is a microprocessor belonging to the PowerQUICC family, manufactured by NXP Semiconductors. It features a single-core PowerPC architecture 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 16 kB of L1 instruction cache and 8 kB of L1 data cache. It functions on a 3.3 V supply voltage and supports interfaces such as Ethernet, I2C, SPI, and UART. The component is rated for an operating temperature range from 0°C to +95°C and includes four timers and a watchdog timer.

Feature Summary

• Integrates a high-performance PowerPC core within the PowerQUICC embedded processor family.
• Provides integrated communication peripherals including Ethernet controllers and serial interfaces.
• Features on-chip L1 instruction and data caches for efficient code execution.

Applications

• Network infrastructure equipment
• Industrial control systems
• Embedded communications gateways

Procurement Notes

Verify the specific suffix 'Z' against official NXP documentation to confirm lead-free status and RoHS compliance details. Confirm current lifecycle status as this series may be discontinued or subject to obsolescence notices. Ensure compatibility with existing PCB footprints for the PBGA-357 package before procurement.

Selection Notes

Select this component when a dedicated PowerQUICC solution with integrated Ethernet and standard serial interfaces is required. Compare L1 cache sizes and thermal specifications against similar models like the MPC860ENVR66D4 to ensure suitability for the target application's performance and environmental constraints.

Part Context

This part is a member of the broader PowerQUICC II family of communications processors. It shares architectural similarities with other devices in the series but is distinguished by its specific clock speed, package type, and cache configuration. It serves as a specialized microprocessor for embedded networking tasks.

Replacement Considerations

Consult official substitution guides for equivalent parts within the MPC860 series. Verify pin-to-pin compatibility and electrical characteristics if replacing with variants such as the MPC860DPVR80D4 or MPC860ENVR66D4.
