MPC866PVR100A

The MPC866PVR100A is a single‑chip embedded microprocessor based on a single‑issue, 32‑bit PowerPC core. Designed for controller, communications and networking applications, the device integrates processing, memory management and communications peripherals on a single surface‑mount PBGA package to simplify system design.

Key value comes from integrated communications support, on‑chip MMU and caches, and a compact 357‑pin PBGA footprint—offering a balance of performance, integration and board‑level density for consumer and embedded designs.

Key Features

• Core  Single‑issue 32‑bit PowerPC core running at 100 MHz, providing a deterministic embedded processing engine.
• Caches and MMU  On‑chip caches (16 KB instruction, 8 KB data for MPC866P) with cache coherency on 128‑bit blocks, and MMUs with a 32‑entry fully associative instruction and data TLB supporting multiple page sizes.
• Communications Co‑processor (CPM)  Integrated communications co‑processor functionality for handling protocol offload and serial communications tasks.
• Ethernet Interfaces  Multiple Ethernet controllers: four 10 Mbps interfaces and one 10/100 Mbps interface to support varied network topologies.
• Peripheral Interfaces  Built‑in HDLC/SDLC support and other communications peripherals for protocol framing and serial link management.
• Memory Controller  On‑chip DRAM controller for system memory interfacing and streamlined board design.
• Power and I/O  3.3 V I/O signaling for common embedded system compatibility.
• Package and Mounting  357‑pin PBGA (25 × 25 mm) surface‑mount package for compact integration onto high‑density PCBs.
• Operating Range  Qualified for consumer applications with an operating temperature range of 0 °C to 95 °C.
• RoHS Compliance  RoHS‑compliant device suitable for modern environmental requirements.

Typical Applications

• Communications Equipment  Protocol handling, framing and multiple Ethernet interfaces make the MPC866PVR100A suitable for small routers, switches and network appliances.
• Embedded Controllers  Single‑chip integration of CPU, MMU and DRAM controller supports industrial and consumer controller designs that require compact processing and communications capability.
• Networking Appliances  Integrated CPM and HDLC/SDLC interfaces enable offload of serial communications and protocol tasks in networking endpoints and gateway devices.

Unique Advantages

• Integrated Communications Subsystem: On‑chip CPM and HDLC/SDLC support reduce external peripheral count and simplify firmware partitioning for protocol tasks.
• Balanced On‑Chip Memory Architecture: Instruction and data caches plus a 32‑entry MMU TLB provide predictable performance for embedded workloads.
• Multiple Ethernet Ports: Four 10 Mbps and one 10/100 Mbps interfaces support flexible network configurations without added MAC components.
• Compact PBGA Package: 357‑pin PBGA (25 × 25 mm) enables high‑density board layouts while keeping I/O and power routing consolidated.
• Industry‑Standard I/O Voltage: 3.3 V I/O compatibility eases integration with a wide range of peripheral devices and standard board components.
• RoHS‑Compliant: Meets environmental requirements for modern electronic assemblies.
