MPC855TCVR50D4R2

The MPC855TCVR50D4R2 is a single-core, 32-bit microprocessor from the MPC8xx family, specified at 50 MHz and designed for embedded communications and industrial applications. It integrates communications co-processing, DRAM control and Ethernet interfaces to deliver a compact, industrial-grade processing building block for networked and embedded systems.

Key Features

• Core  Single 32-bit MPC8xx core running at 50 MHz, suitable for deterministic embedded processing tasks.
• Communications Co-processor (CPM)  Integrated CPM for offloading communications and protocol processing, enhancing system-level throughput for protocol-heavy applications.
• Memory Controller  Built-in DRAM controller to support external memory configurations required by embedded operating environments.
• Ethernet Interfaces  Provides one 10 Mbps and one 10/100 Mbps Ethernet interface for network connectivity and varied PHY link speeds.
• Serial Protocol Support  Additional interfaces including HDLC/SDLC support for synchronous serial communications.
• Power and I/O  3.3 V I/O voltage for compatibility with common embedded peripherals and interface components.
• Package and Mounting  Surface-mount 357-pin PBGA in a 25×25 mm footprint for compact board-level integration.
• Industrial Temperature Range  Rated for −40 °C to 95 °C operation to meet demanding environmental requirements.
• Regulatory  RoHS compliant, supporting environmental and manufacturing requirements.

Typical Applications

• Embedded Communications Equipment  Use as the processing core in routers, gateways or protocol converters where integrated CPM and Ethernet interfaces are required.
• Industrial Control Systems  Suitable for PLCs, motor controllers or remote I/O where the industrial temperature rating and DRAM controller are important.
• Networked Monitoring and Telemetry  Ideal for data acquisition nodes and telemetry devices that need deterministic processing and both 10 Mbps and 10/100 Mbps connectivity.
• Legacy and Protocol-Specific Devices  Appropriate for designs that require HDLC/SDLC support and dedicated communications offload.

Unique Advantages

• Integrated Communications Processing: On-chip CPM co-processor reduces host CPU load for protocol handling and communications tasks.
• Dual Ethernet Capability: Combines a 10 Mbps and a 10/100 Mbps Ethernet interface to support mixed network link requirements.
• Industrial Qualification: −40 °C to 95 °C operating range enables deployment in harsh or temperature-variable environments.
• Compact PBGA Package: 357-pin PBGA (25×25 mm) minimizes PCB area while exposing rich I/O and memory interfaces.
• Standard 3.3 V I/O: Simplifies integration with common embedded peripherals and reduces the need for level translation.
• RoHS Compliant: Meets lead-free manufacturing and environmental compliance requirements.
