MPC850DECVR66BU

The MPC850DECVR66BU is a single‑core, 32‑bit microprocessor based on the MPC8xx architecture, running at 66 MHz. It integrates a communications processor module (CPM) and system peripherals to serve embedded communications and networking applications where integration, predictable I/O, and industrial temperature operation matter.

Designed for embedded and telecommunications controller applications, the device combines on‑chip communications channels, a DRAM controller and an 8‑Kbyte dual‑port RAM to simplify system design while supporting a 3.3 V I/O environment and industrial operation from -40 °C to 95 °C.

Key Features

• Core – Embedded single‑issue, 32‑bit MPC8xx core operating at 66 MHz with 32 general‑purpose registers, providing a standard PowerPC‑style execution environment.
• Communications Processor Module (CPM) – Integrated CPM includes a separate RISC communications processor that off‑loads peripheral tasks; the CPM supports up to seven serial channels including SCCs (Ethernet/HDLC), USB, SMCs, I²C and SPI.
• Memory Support – On‑chip DRAM controller plus an 8‑Kbyte dual‑port RAM for high‑efficiency buffer management and shared data handling between host core and CPM.
• Interfaces – Integrated Ethernet (10 Mbps, 1 port), USB 1.x (1 port), HDLC/SDLC and additional serial management channels suitable for communications protocols and serial peripherals.
• Power and I/O – 3.3 V I/O supply for common embedded system compatibility.
• Package and Mounting – 256‑ball PBGA package (23 × 23 mm) for surface mount assembly with compact board area.
• Operating Range and Qualification – Industrial qualification with operating temperature range of -40 °C to 95 °C and RoHS compliance.
• Graphics – No graphics acceleration, focused on communications and control tasks.

Typical Applications

• Telecommunications Access – Implements protocol handling and packet/serial off‑load for remote access and telco interface controllers.
• Embedded Networking Equipment – Acts as a compact communications processor for small routers, gateways and protocol converters that require integrated Ethernet and serial channels.
• Industrial Communications Modules – Performs deterministic I/O and serial protocol handling in industrial control and monitoring systems across wide temperature ranges.
• Peripheral Interface Controllers – Uses on‑chip CPM, USB and serial interfaces to manage multiple peripheral links with reduced host load.

Unique Advantages

• Integrated CPM Off‑load: Reduces host core workload by handling serial protocol tasks independently, simplifying firmware partitioning and improving overall throughput.
• Compact, Surface‑Mount Package: 256‑PBGA (23 × 23 mm) provides high pin density for multiple interfaces while minimizing PCB footprint.
• Industrial Temperature Capability: Rated from -40 °C to 95 °C to suit harsh operating environments and extended‑temperature deployments.
• Broad Interface Set: Built‑in Ethernet, USB 1.x, HDLC/SDLC and serial management channels enable versatile connectivity options without extensive external logic.
• System Memory Features: DRAM controller plus 8‑Kbyte dual‑port RAM support efficient buffering and shared access between core and communications engine.
• Standards‑Friendly I/O Voltage: 3.3 V I/O simplifies integration with common embedded peripherals and transceivers.

Why Choose MPC850DECVR66BU?
