MPC850DECVR50BU

Overview

The MPC850DECVR50BU is a microprocessor IC from the MPC8xx family, manufactured by NXP USA Inc. It features a single 32-bit core operating at 50 MHz within a 256-pin PBGA package measuring 23x23 mm. The device integrates an embedded PowerPC architecture core with 2-Kbyte instruction cache and 1-Kbyte data cache. Key peripherals include two serial communications controllers (SCCs), USB support, PCMCIA interface, and a Communications Processor Module (CPM) with up to 8 Kbytes of dual-port RAM.

Feature Summary

• Integrates a high-performance embedded MPC8xx core with Harvard architecture caches and memory management units.
• Includes a dedicated Communications Processor Module (CPM) with a scalar RISC processor to offload peripheral tasks.
• Supports multiple communication protocols including Ethernet, HDLC, SDLC, UART, and IrDA via SCCs and SMCs.
• Features universal serial bus (USB) controller supporting host and slave modes.

Applications

• Cost-sensitive remote-access networking products
• Telecommunications applications
• Controller applications requiring integrated communications

Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete. Confirm datasheet revision matches design requirements. Check for moisture sensitivity level compliance during storage and handling. Ensure voltage levels align with system specifications before integration.

Selection Notes

Select this model when dual serial communications controllers are required alongside USB functionality. Compare against MPC850 variants lacking specific protocol support or additional SCCs. Evaluate thermal characteristics and power dissipation limits for the target application environment.

Part Context

This component belongs to the MPC8xx series of PowerQUICC integrated communications processors. It shares architectural similarities with the MPC860 but offers specific enhancements such as USB support and increased dual-port RAM capacity. The device is designed for high integration in embedded systems.

Replacement Considerations

Consult official documentation for direct substitutes. Verify pin compatibility and feature parity if considering alternative MPC8xx family members.
