MPC853TVR66A

The MPC853TVR66A is a single‑core, 32‑bit microprocessor in the MPC8xx family, supplied in a 256‑pin PBGA (23×23) surface‑mount package. It combines a PowerPC‑architecture MPC8xx core running at 66 MHz with integrated communications peripherals targeted at embedded Ethernet and communications control applications.

Designed for consumer‑grade embedded systems, the device delivers integrated I/O, DRAM controller support and a Communications Processor Module (CPM) to simplify board-level design while meeting common temperature and voltage requirements for commercial products.

Key Features

• Core  MPC8xx PowerPC‑architecture core, single 32‑bit processor configured for 66 MHz operation.
• Performance & Memory  Includes instruction and data caches and memory management units (MMUs); integrates DRAM controller support for system memory.
• Communications Processing  On‑chip Communications Processor Module (CPM) and communications DSP functions to support protocol handling and offload.
• Ethernet & Serial Interfaces  Provides a 10 Mbps Ethernet interface (1) and serial protocol support including HDLC/SDLC for common communication links.
• Voltage & I/O  3.3 V I/O operation (Voltage Io: 3.3 V) with core/IO voltage segmentation described in the hardware specification.
• Package & Mounting  256‑PBGA (23×23) package (surface mount) for compact, high‑density board designs.
• Operating Range  Consumer qualification with an operating temperature range of 0 °C to 95 °C.
• Environment  RoHS compliant.

Typical Applications

• Ethernet control equipment  Use the integrated CPM and Ethernet interface for control plane and management functions in Ethernet devices.
• Customer premises equipment (CPE)  Suitable for embedded CPE designs that require on‑chip communications peripherals and DRAM support.
• Routers and hubs  Applied where a compact, single‑chip communications controller with HDLC/SDLC support and Ethernet I/O is needed.
