MPC850SRVR80BU

The MPC850SRVR80BU is a member of the MPC850 family: a single‑core, 32‑bit microprocessor based on the MPC8xx core running at 80 MHz. It integrates a Communications Processor Module (CPM) and system peripherals targeted at communications, remote‑access and telecommunications applications where integration and peripheral off‑load are important.

Designed for cost‑sensitive embedded and networking products, the device provides on‑chip memory support, serial interfaces and industry standard I/O levels, delivering a compact, surface‑mount solution in a 256‑pin PBGA (23×23) package.

Key Features

• Core – Embedded single‑issue MPC8xx core, 32‑bit architecture running at 80 MHz for deterministic embedded processing.
• Communications Processor Module (CPM) – Integrated CPM with a dedicated RISC communications processor (CP) that off‑loads peripheral tasks from the main core.
• Serial Channel Support – CPM supports up to seven serial channels including SCCs (for Ethernet, ATM, HDLC/SDLC), USB, two SMCs, I2C and SPI.
• Ethernet and USB – On‑chip Ethernet support (10 Mbps) and one USB 1.x channel for networked and peripheral connectivity.
• Memory and DRAM Controller – Integrated DRAM controller and an 8‑Kbyte dual‑port RAM to support system buffering and shared memory tasks.
• Interfaces – Additional protocols include HDLC/SDLC and support for serial management controllers for diverse communications needs.
• Power and I/O – 3.3 V I/O signaling compatible with common embedded system voltages.
• Package and Mounting – 256‑PBGA (23×23) surface‑mount package for compact board integration.
• Temperature and Qualification – Consumer‑grade qualification with an operating temperature range of 0 °C to 95 °C.

Typical Applications

• Communications and Networking Equipment – Ideal for routers, access gateways and network appliances that require integrated Ethernet, HDLC and serial channel support.
• Remote‑Access and Telecommunications Devices – Suited for remote‑access controllers and telecom equipment where CPM off‑load and USB connectivity simplify design.
• Embedded Control Systems – Useful in cost‑sensitive embedded controllers that need a compact, single‑chip solution with on‑chip DRAM support and multiple serial interfaces.

Unique Advantages

• Integrated Communications Off‑load: The CPM with a dedicated communications processor reduces CPU overhead for protocol handling and serial traffic management.
• Consolidated Peripherals: On‑chip Ethernet, USB 1.x, HDLC/SDLC and multiple serial controllers reduce external component count and simplify BOM.
• Shared Buffering: Built‑in 8‑Kbyte dual‑port RAM supports efficient data exchange between the core and CPM for real‑time communications tasks.
• Compact Surface‑Mount Package: 256‑pin PBGA (23×23) delivers a small footprint for dense board layouts and space‑constrained designs.
• Standard 3.3 V I/O: Compatible I/O voltage simplifies integration with common embedded peripherals and board power domains.
• Designed for Cost‑Sensitive Designs: Feature set and integration are targeted toward systems where minimizing components and board complexity matters.
