MPC850DSLVR50BU

Overview

The MPC850DSLVR50BU is a PowerQUICC integrated communications processor manufactured by NXP USA Inc. It features a single-core, 32-bit MPC8xx processor core operating at 50 MHz within a 256-pin PBGA package measuring 23x23 mm. The device supports 3.3V I/O voltage and operates within a temperature range of 0°C to 95°C. Key interfaces include Ethernet (10 Mbps), USB 1.x, PCMCIA-ATA, HDLC/SDLC, I2C, IrDA, TDM, and UART/USART. It incorporates a Communications Processor Module (CPM) with DRAM controller capabilities.

Feature Summary

• Integrates an embedded MPC8xx core with a dedicated Communications Processor Module (CPM) for offloading peripheral tasks
• Supports multiple serial communication protocols including Ethernet, HDLC, SDLC, and ATM via Serial Communications Controllers
• Includes a Universal Serial Bus (USB) controller supporting host and slave modes
• Features a versatile memory controller compatible with various memory types such as DRAM and SRAM

Applications

• Cost-sensitive remote-access applications
• Telecommunications products
• Controller applications in networking environments

Procurement Notes

Verify the specific suffix 'DSLVR50BU' against official NXP documentation to confirm pinout, speed grade, and package variations. Confirm RoHS compliance status and check for obsolescence notices, as this component may be part of a legacy portfolio. Ensure thermal management solutions align with the specified junction temperature ratings during system design.

Selection Notes

Select this component for designs requiring a high-performance RISC core combined with extensive on-chip communication peripherals. The integration of the CPM reduces external logic requirements. Consider the 50 MHz operational frequency and 256-pin BGA package constraints for PCB layout and cooling when evaluating suitability for space-constrained or thermally sensitive enclosures.

Part Context

This part belongs to the MPC850 family within the PowerQUICC series, designed for embedded communications processing. It shares architectural similarities with the MPC860 but adds USB support and enhanced dual-port RAM. The DSL variant specifically includes ATM support alongside Ethernet and HDLC capabilities, targeting advanced telecommunications controller needs.

Replacement Considerations

Consult official NXP substitution guides for verified alternatives. Generic cross-references are not supported due to specific peripheral configurations like the DSL interface set.
