MPC850DSLCVR50BU

Overview

The MPC850DSLCVR50BU is a PowerQUICC integrated communications processor featuring an embedded 32-bit MPC8xx core operating at 50 MHz. It includes a Communications Processor Module (CPM) with two Serial Communications Controllers (SCCs), USB support, and ATM capability. The device utilizes a 256-pin PBGA package and operates on 3.3V I/O voltage.

Feature Summary

• Integrates a high-performance embedded MPC8xx core with a separate RISC Communications Processor Module to offload peripheral tasks.
• Supports Ethernet, ATM, HDLC, and Universal Serial Bus protocols via dedicated controllers within the CPM.
• Features a versatile memory controller supporting DRAM, SRAM, and flash interfaces with glueless SIMM compatibility.

Applications

• Cost-sensitive remote-access networking equipment
• Telecommunications controller applications
• Integrated communications processors requiring protocol handling

Procurement Notes
