MPC850DEVR50BU

Overview

The MPC850DEVR50BU 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 supports 3.3V I/O voltage and operates within a temperature range of 0°C to 95°C (TA). Key integrated peripherals include Ethernet support, USB 1.x, HDLC/SDLC, I2C, IrDA, PCMCIA-ATA, TDM, and UART/USART interfaces.

Feature Summary

• Integrates an embedded 32-bit MPC8xx core with Harvard architecture instruction and data caches.
• Includes a Communications Processor Module (CPM) with a dedicated RISC processor to offload peripheral tasks.
• Supports dual-port RAM for efficient data handling between the core and communication modules.
• Features a versatile memory controller compatible with various external memory types.

Applications

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

Procurement Notes

Verify the specific suffix 'DE' indicates two Serial Communications Controllers (SCCs), as opposed to one in the base model. Confirm the 'VR' suffix corresponds to the 50 MHz speed grade and commercial temperature range. Ensure the 'BU' suffix matches the required 256-PBGA package variant. Cross-reference the datasheet revision to confirm compatibility with your system design requirements.

Selection Notes

Select this component when a balance of processing power and integrated communication protocols is required. The inclusion of two SCCs makes it suitable for designs needing multiple serial channels compared to the standard MPC850. Consider the 50 MHz performance limit and the specific interface set including USB and Ethernet when evaluating against other members of the MPC8xx family.

Part Context

This part belongs to the PowerQUICC series, designed for embedded communications processing. It utilizes the PowerPC architecture and integrates system functions like a memory controller and CPM. The MPC850 family targets applications similar to the MPC860 but with enhancements such as USB support and larger dual-port RAM, focusing on cost-effective solutions for networking and telecom.
