MPC855TVR50D4

The MPC855TVR50D4 is a single‑core, 32‑bit MPC8xx microprocessor operating at 50 MHz, designed for cost‑sensitive networking and embedded communications applications. It integrates an MPC8xx core, an on‑chip Communications Processor Module (CPM), and a dedicated 10/100-Mbps Fast Ethernet controller to consolidate control and connectivity functions in a compact package.

Targeted use cases include small office/home office (SOHO) routers, ADSL and cable modem controllers, and other general purpose networking devices where integration, predictable interface support, and low system cost are priorities.

Key Features

• Core – Single MPC8xx 32‑bit core running at 50 MHz for general‑purpose application processing.
• Communications Processor Module (CPM) – Embedded RISC communications processor for offloading protocol and channel processing tasks, including support for HDLC/SDLC and multichannel protocols.
• Ethernet Connectivity – Integrated 10/100‑Mbps Fast Ethernet controller with on‑chip FIFOs and bursting DMA; supports multiple physical interfaces including MII and 7‑wire 10‑Mbps interface and operates full‑duplex 100‑Mbps at the 50 MHz system clock.
• Multichannel & Protocol Support – CPM and QMC protocol support enable multichannel protocol processing, with documented capability to handle time‑division‑multiplexed channels for protocol processing at 50 MHz.
• Memory Controller – Integrated DRAM controller and provision for on‑chip dual‑port RAM to support communications buffering and shared memory between core and CPM.
• Interfaces – Additional interface support includes HDLC/SDLC and a communications‑oriented peripheral set appropriate for networking applications.
• Package & Mounting – 357‑PBGA (25 × 25 mm) surface‑mount package for compact board implementation.
• Power & Voltage – 3.3 V I/O voltage for common embedded system compatibility.
• Operating Range & Qualification – Consumer qualification with an operating temperature range of 0 °C to 95 °C; RoHS compliant.

Typical Applications

• SOHO Routers – Use the integrated Ethernet controller and CPM to handle packet processing, offload protocol tasks, and simplify board design for small network gateways.
• ADSL and Cable Modems – Integrated communications processing and DRAM controller support modem front‑end buffering and multichannel protocol handling in access network devices.
• Cost‑Sensitive Networking Equipment – Consolidate control, protocol processing, and Ethernet MAC functions in a single device to reduce BOM and board complexity for entry‑level networking products.
• Telecommunications Controllers – Leverage CPM multichannel and HDLC/SDLC support for channelized protocol processing and telecom interface tasks.

Unique Advantages

• Integrated Communications Subsystem: On‑chip CPM plus the MPC8xx core provides dedicated resources for protocol processing and application tasks, reducing the need for external processors.
• Built‑in 10/100 Mbps Ethernet MAC: Fast Ethernet controller with FIFOs and DMA enables high‑throughput connectivity without taxing the main core.
• Multichannel Protocol Support: CPM and QMC protocol capabilities enable TDM channel processing and HDLC/SDLC handling suitable for multiport and telecom applications.
• Compact PBGA Package: 357‑PBGA (25×25) surface‑mount package allows a small PCB footprint for space‑constrained designs.
• Consumer‑Grade Temperature & Compliance: 0 °C to 95 °C operating range and RoHS compliance meet common requirements for consumer networking products.
• 3.3 V I/O Compatibility: Standard 3.3 V I/O simplifies integration with common peripherals and PHY devices.
