MPC850CZQ50BUR2

Overview

The MPC850CZQ50BUR2 is a PowerQUICC integrated communications processor featuring an embedded single-issue, 32-bit MPC8xx core implementing the PowerPC architecture. It includes a 32-bit RISC Communications Processor Module (CPM) with up to 8-Kbyte dual-port RAM and supports Ethernet, USB, HDLC, and ATM protocols. The device operates at frequencies up to 80 MHz with a maximum bus speed of 50 MHz. It utilizes a BGA package and supports 3.3-V operation with 5-V TTL compatibility on general-purpose I/O pins.

Feature Summary

• Integrated 32-bit RISC Communications Processor Module (CPM) offloads peripheral tasks from the main core
• Supports multiple serial channels including Ethernet, USB, SCCs, SMCs, SPI, and I2C
• Features advanced on-chip emulation debug mode with watchpoints and breakpoints
• Provides low-power support modes including Doze, Sleep, Deep Sleep, and Low-power stop

Applications

• Cost-sensitive remote-access applications
• Telecommunications products
• Networking products
• Controller applications requiring Ethernet and USB support

Procurement Notes

Verify that the specific suffix ZQ50BUR2 corresponds to the required frequency rating, package type, and temperature range as defined in the official datasheet. Confirm that the ordering information matches the exact part number variant intended for your design requirements before finalizing procurement.

Selection Notes

Select this component when a versatile, one-chip solution combining a high-performance embedded MPC8xx core with a dedicated communications processor module is required. It is suitable for designs needing integrated Ethernet, USB, and flexible memory controller interfaces within a single package.

Part Context

The MPC850 belongs to the Freescale Semiconductor PowerQUICC family, which was later acquired by NXP Semiconductors. This series provides integrated microprocessor and peripheral combinations designed for cost-sensitive networking and telecommunications markets.

Replacement Considerations

The MPC860 offers similar functions but lacks the universal serial bus (USB) support and larger dual-port RAM found in the MPC850.
