MPC885VR80

Microprocessors Overview

The MPC885VR80 is a 32-bit microprocessor from the PowerQUICC family, operating at an 80 MHz frequency. It integrates an embedded MPC8xx core with a dedicated Communications Processor Module (CPM) for protocol handling. The device features 8 KB instruction and data caches, dual Fast Ethernet controllers, USB 2.0 support, and a hardware security engine. It utilizes a 1.8 V core voltage with 3.3 V I/O levels and is housed in a 357-pin PBGA package.

Microprocessors Feature Summary

• Dual-processor architecture combining an embedded MPC8xx core with a separate RISC-based CPM for efficient communication task offloading.
• Integrated hardware security engine supporting DES, 3DES, AES, SHA, and MD5 algorithms for IPsec and SSL/TLS processing.
• Enhanced ATM functionality with UTOPIA interface support and simultaneous MII/UTOPIA capability.
• Comprehensive peripheral set including dual Fast Ethernet, USB host/device, PCMCIA, and multiple serial controllers.

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 VR80 against official NXP documentation to confirm the 80 MHz speed grade and lead-free status. Ensure compatibility with existing board designs regarding the 357-pin PBGA footprint and thermal requirements. Confirm that the 1.8V core and 3.3V I/O power sequencing align with system power supply capabilities to prevent reliability issues.

Microprocessors Selection Notes

Select this component when a single-chip solution is required for communications applications needing both general-purpose processing and dedicated protocol handling. The MPC885VR80 is suitable for designs requiring on-chip security acceleration and multiple high-speed interfaces like Ethernet and USB. Consider the 80 MHz performance level relative to higher-frequency variants if cost or power consumption are primary constraints.
