MPC850DSLZQ50BU

Overview

The MPC850DSLZQ50BU is a PowerQUICC integrated communications processor manufactured by NXP USA Inc. It features an embedded single-issue, 32-bit MPC8xx core operating at 50 MHz within a 256-pin PBGA (23x23) package. The device integrates a Communications Processor Module (CPM) with two Serial Communications Controllers (SCCs), a USB controller, and dual UTOPIA ports for ATM support. It includes a versatile memory controller supporting DRAM and SRAM, along with PCMCIA-ATA interfaces.

Feature Summary

• Integrates a high-performance embedded MPC8xx core with a separate 32-bit RISC Communications Processor to off-load peripheral tasks
• Supports Ethernet, HDLC/SDLC, and ATM protocols via dual SCCs and dedicated UTOPIA ports
• Includes a universal serial bus (USB) controller compatible with USB 1.x specifications
• Features a versatile memory controller capable of interfacing with various memory types including DRAM and SRAM

Applications

• Cost-sensitive remote-access networking equipment
• Telecommunications applications requiring protocol processing
• Controller applications utilizing Ethernet and ATM connectivity

Procurement Notes

Verify the specific suffix ZQ50BU against official documentation to confirm pinout and thermal characteristics. Confirm RoHS compliance status as datasheets may indicate non-compliance for older revisions. Ensure the obsolete part status is acceptable for the intended design lifecycle before procurement.

Selection Notes

Select this component when a solution combining PowerPC architecture with dedicated hardware protocol handling is required. The integration of the CPM allows the main core to focus on control plane tasks while the CP handles data plane operations. Verify that the 50 MHz speed and 256-pin BGA package fit the system constraints.
