MPC850SRVR50BU

The MPC850SRVR50BU is an integrated microprocessor IC from NXP Semiconductors featuring a single 32-bit MPC8xx core running at 50 MHz. Designed for communications and embedded controller applications, the device combines a PowerPC-based core with a Communications Processor Module (CPM) and integrated system functions to address cost-sensitive remote-access and telecommunications applications.

This device provides on-chip peripheral support including Ethernet, USB 1.x, HDLC/SDLC and DRAM memory control, packaged in a 256‑PBGA (23×23) surface-mount package and specified for operation from 0 °C to 95 °C. The part is RoHS compliant and carries a consumer qualification level.

Key Features

• Core  Embedded single-issue, 32‑bit MPC8xx core (one core) delivering deterministic control for embedded communications tasks.
• Performance  50 MHz core clock suitable for cost-sensitive controller applications.
• Communications Processor Module (CPM)  Integrated CPM includes a separate RISC communications processor to off-load peripheral tasks and supports up to seven serial channels.
• Serial and Peripheral Interfaces  Single USB 1.x channel, single 10 Mbps Ethernet interface, HDLC/SDLC support, two serial management controllers, SPI and I²C as part of the CPM feature set.
• Memory and Bus  On-chip support for DRAM controllers and an 8‑Kbyte dual-port RAM (as documented for the MPC850 family) to assist data buffering and inter-processor communication.
• Package and Mounting  256‑PBGA (23×23) / 256‑BBGA surface-mount package for high-density board designs.
• Electrical  3.3 V I/O supply level for common embedded system compatibility.
• Operating Range & Compliance  Rated for operation from 0 °C to 95 °C and RoHS compliant; consumer qualification level.
• Integration for Networking  Built-in CPM serial controllers and support for Ethernet and USB reduce external component requirements for communication-focused designs.
• Graphics  No dedicated graphics acceleration; focus is on communications and control functionality.

Typical Applications

• Remote-access and Telecommunications Equipment  Use the integrated CPM, Ethernet and HDLC/SDLC support to implement remote-access controllers and telecom interfaces in cost-sensitive systems.
• Embedded Networking Appliances  Single-core MPC8xx performance with on-chip USB and Ethernet makes the part suitable for compact networking or management nodes.
• Controller and Gateway Devices  DRAM controller support and the CPM’s serial channels allow use as a gateway or protocol converter in embedded networks.

Unique Advantages

• Integrated Communications Off-load: The CPM’s dedicated communications processor off-loads peripheral and serial protocol handling from the main MPC8xx core, simplifying real-time design.
• Compact Packaging: 256‑PBGA (23×23) surface-mount package enables a high-density board footprint for space-constrained embedded systems.
• Well-documented Hardware: The MPC850 family is supported by published hardware specifications and datasheet content that detail power, timing and interfacing characteristics.
• Common I/O Voltage: 3.3 V I/O simplifies integration with standard embedded components and memory interfaces.
• Focused Feature Set for Cost-sensitive Designs: A balanced mix of core performance, CPM-based communications and on-chip DRAM support reduces external BOM for networking-centric products.
• RoHS Compliant: Environmentally compliant construction suitable for current procurement and manufacturing requirements.
