MPC870VR133

Microprocessors Overview

The MPC870VR133 is a PowerQUICC processor featuring an embedded MPC8xx core operating at 133 MHz. It integrates a Communications Processor Module (CPM), System Integration Unit (SIU), and memory controller. The device supports dual Fast Ethernet, USB 2.0 full/low-speed, PCMCIA, and serial interfaces including SCC and SMC. It utilizes a 256-pin PBGA package with 1.8V core and 3.3V I/O voltages.

Microprocessors Feature Summary

• Integrates an embedded MPC8xx core with a separate RISC CPM for communications handling
• Includes dual Fast Ethernet controllers and USB host/device capabilities
• Features on-chip security engine for IPsec and SSL/TLS processing
• Supports PCMCIA interface for wireless module connectivity

Microprocessors Applications

• Low-end routers
• VPN routers with integrated security features
• Home networking equipment
• Cost-effective WLAN access points
• xDSL gateway boxes

Microprocessors Procurement Notes

Verify the specific suffix VR133 against official NXP documentation to confirm the 133 MHz frequency rating and extended temperature range specifications. Ensure compatibility with existing board designs regarding the 256-pin PBGA footprint and power sequencing requirements for the 1.8V core and 3.3V I/O supplies.

Microprocessors Selection Notes

Select this component for applications requiring high integration of networking peripherals within a single chip. The MPC870 lacks the on-chip security engine found in the MPC875 variant; therefore, evaluate if external security solutions are necessary. Consider the 133 MHz core speed relative to the 80 MHz maximum bus frequency when designing system timing constraints.

Microprocessors Part Context

The MPC870 belongs to the MPC885 family of PowerQUICC processors. This family shares a common architecture but varies in peripheral availability. The MPC870 is distinguished by its lack of an on-chip security engine compared to the MPC875, while maintaining similar core performance and communication interface support.

Microprocessors Replacement Considerations

The MPC875 is a pin-compatible alternative within the same family that includes an integrated security engine. Verify functional requirements to determine if the additional security hardware in the MPC875 is necessary or if the MPC870's feature set is sufficient.
