MPC850SRVR80BU

Overview

The MPC850SRVR80BU is a PowerQUICC integrated communications processor featuring an embedded 32-bit MPC8xx core. It supports Ethernet, ATM, USB, and multi-channel HDLC protocols. The device includes two Serial Communications Controllers (SCCs), a Communications Processor Module (CPM) with up to 8-Kbyte dual-port RAM, and a single PCMCIA slot. Operating at 80 MHz, it utilizes a BGA package and supports 3.3-V logic with 5-V TTL compatibility.

Feature Summary

• Integrated 32-bit RISC Communications Processor (CP) offloads peripheral tasks from the main core.
• Supports Ethernet, ATM, USB, and multi-channel HDLC via dedicated controllers.
• Features a completely static design allowing operation down to 0 MHz.
• Includes advanced on-chip emulation debug mode with hardware breakpoints.

Applications

• Cost-sensitive remote-access networking equipment
• Telecommunications controller applications
• Ethernet and ATM based communication products

Procurement Notes

Verify the specific suffix 'R80BU' against official NXP documentation to confirm pinout, temperature range, and packaging details. Ensure the source document explicitly defines this suffix variant, as ordering codes may dictate specific mechanical or electrical constraints not covered by the base part number.

Selection Notes

Select this component for designs requiring high integration of serial interfaces and network protocols in a single chip. It is suitable for applications needing USB host/slave capabilities alongside Ethernet and ATM support. Consider the 80 MHz operating speed and BGA package constraints during PCB layout.

Part Context

This part belongs to the Freescale Semiconductor MPC850 family, which was later acquired by NXP Semiconductors. The MPC850 series provides a versatile microprocessor and peripheral combination designed for cost-sensitive communications and networking products, offering functions similar to the MPC860 with added USB support.
