KMPC885CZP133

Microprocessors Overview

The KMPC885CZP133 is a 32-bit microprocessor from the MPC8xx series, manufactured by NXP USA Inc. It operates at a CPU frequency of 133 MHz and utilizes a 357-pin PBGA package with dimensions of 25x25 mm. The device integrates an embedded PowerPC core and a Communications Processor Module (CPM). It supports dual Fast Ethernet ports, USB 2.0 full/low-speed compatibility, PCMCIA, UART, HDLC, ATM, I2C, IrDA, SPI, TDM, and timers. The processor features 8 KB instruction cache and 8 KB data cache, along with on-chip security engines supporting AES, DES/3DES, SHA, MD5, and HMAC. It functions with a 1.8V core voltage and 3.3V I/O levels, operating within a temperature range of -40°C to 100°C.

Microprocessors Feature Summary

• Integrates an embedded 8xx core with a separate RISC processor CPM for efficient communications handling
• Includes on-chip security engine supporting standard cryptographic algorithms such as AES, DES/3DES, SHA, and MD5
• Provides dual Fast Ethernet ports alongside USB host/device capabilities and PCMCIA support

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 'CZP133' against official NXP documentation to confirm pinout, voltage, and temperature grade alignment. Confirm current availability status as older MPC8xx components may be discontinued or require alternative sourcing strategies. Ensure design-in compatibility with existing PCB footprints for the 357-pin PBGA package.

Microprocessors Selection Notes

Select this component when a single-chip solution combining general-purpose processing with dedicated communications offloading is required. The integration of the CPM allows the main core to focus on control tasks while handling network protocols. Consider the 133 MHz speed and available peripheral set for applications needing robust connectivity without external protocol controllers.
