MPC870VR66

Microprocessors Overview

The KMPC870CVR66 is a PowerQUICC microprocessor IC from the MPC8xx series, manufactured by NXP USA Inc. It features a single 32-bit core operating at 66 MHz within a 256-pin PBGA package (23x23 mm). The device integrates dual Fast Ethernet controllers supporting 10/100 Mbps speeds and includes USB 2.0 compatibility. Key interfaces include I2C, PCMCIA, SPI, TDM, and UART. Operating temperatures range from -40°C to 100°C with 3.3V I/O voltage.

Microprocessors Feature Summary

• Integrates an embedded MPC8xx core with a separate Communications Processor Module (CPM) for efficient communications handling
• Supports dual Fast Ethernet ports via MII/RMII interfaces and USB 2.0 full/low-speed host/device functionality
• Includes on-chip memory controllers for DRAM, SRAM, and Flash EPROMs with glueless interface capabilities
• Provides extensive serial communication options including SCC, SMC, SPI, I2C, and PCMCIA master interfaces

Microprocessors Applications

• Low-end routers and VPN routers with integrated security features
• Home networking equipment and cost-effective WLAN access points
• xDSL gateway boxes and small enterprise gateways
• Communications controller applications requiring ATM or HDLC support

Microprocessors Procurement Notes

Verify component authenticity through authorized distributors as this part is marked obsolete. Confirm RoHS3 compliance status and check for available engineering samples if production quantities are required. Ensure supply chain stability due to end-of-life status and consider long-term availability agreements with NXP. Validate pinout compatibility during replacement planning.

Microprocessors Selection Notes

Select this processor for applications requiring high integration of networking peripherals on a single chip. Consider the 66 MHz operating speed and 256-pin BGA package constraints for PCB layout. Evaluate thermal management requirements given the junction-to-ambient resistance values. Compare against MPC875 if security engine features like DES/AES hardware acceleration are needed, as the MPC870 lacks these specific cryptographic units.

Microprocessors Part Context

This component belongs to the MPC885 family of PowerQUICC processors, which also includes the MPC875, MPC880, and MPC885. These devices share the same Power Architecture-based core and system integration unit but differ in peripheral sets such as Ethernet count and security engines. The MPC870 specifically omits the security engine found in the MPC875 variant while retaining dual Ethernet and USB capabilities.
