MPC850DSLVR50BU

The MPC850DSLVR50BU is a single‑core, 32‑bit microprocessor based on the MPC8xx core, operating at 50 MHz. It integrates a communications-focused architecture with a Communications Processor Module (CPM) and system-level peripherals for cost‑sensitive embedded and networking applications.

Designed for communications and remote‑access use, this device combines on‑chip peripheral processing, DRAM memory controller support, and standard interfaces such as Ethernet and USB to simplify system design and reduce bill‑of‑materials.

Key Features

• Core Single MPC8xx 32‑bit core operating at 50 MHz, suitable for embedded control and communications tasks.
• Communications Processor Module (CPM) Includes an independent RISC communications processor (CP) to off‑load peripheral and protocol handling from the main core.
• Serial and Protocol Interfaces CPM supports multiple serial channels (including SCCs), HDLC/SDLC and USB 1.x, enabling common networking and serial protocol implementations.
• Ethernet One 10 Mbps Ethernet interface for basic network connectivity.
• Memory and Controllers On‑chip support for DRAM controllers and a larger dual‑port RAM architecture (series documentation references an 8‑KB dual‑port RAM).
• Power and I/O 3.3 V I/O voltage compatibility for standard embedded system interfacing.
• Package and Mounting 256‑PBGA package, 23×23 mm footprint; surface‑mount for compact board integration.
• Operating Range Specified for operation from 0 °C to 95 °C, targeting consumer‑grade applications.
• Compliance RoHS compliant.

Typical Applications

• Remote Access and Networking Equipment Provides Ethernet and serial protocol support with CPM off‑load to implement gateways, remote access units, and simple network appliances.
• Telecommunications Controllers Integrated communications processing and HDLC/SDLC interfaces enable protocol handling and line‑side control functions.
• Embedded Communications Devices USB 1.x and serial channels allow device and peripheral connectivity in cost‑sensitive embedded systems.

Unique Advantages

• Integrated Communications Off‑load The CPM includes a dedicated communications processor to handle protocol and peripheral tasks, freeing the main MPC8xx core for application logic.
• Compact Surface‑Mount Package 256‑PBGA (23×23 mm) provides a space‑efficient solution for dense board designs.
• Standard I/O Voltage 3.3 V I/O simplifies interfacing with common peripheral components and memory systems.
• Built‑in Memory Support On‑chip DRAM controller support and series dual‑port RAM simplify system memory architecture and improve data handling between processor and communication subsystems.
• Regulatory‑Friendly RoHS compliance supports modern manufacturing and environmental requirements.
