MPC859PVR133A

The MPC859PVR133A is a single‑core, 32‑bit microprocessor in the MPC8xx family, delivering a 133 MHz PowerPC™‑based core optimized for embedded controller and communications systems. It integrates a communications co‑processor (CPM) and peripheral subsystems to support networking and controller applications where integration, deterministic I/O and legacy communications protocols matter.

Designed for surface‑mount deployment in a 357‑pin PBGA (25×25) package and qualified for consumer applications, the device targets embedded networking, communications and control designs requiring a compact, RoHS‑compliant processor solution with broad I/O and memory controller support.

Key Features

• Core & Architecture  Embedded single‑issue, 32‑bit PowerPC core with thirty‑two 32‑bit general purpose registers and branch prediction with conditional prefetch as documented for the MPC866/859 family.
• Cache & MMU  Implements a 16 KB instruction cache (four‑way set‑associative) and an 8 KB data cache (two‑way set‑associative) for the MPC859P variant; includes MMUs with a 32‑entry TLB and support for multiple page sizes (4, 16 and 512 KB).
• Communications Processor (CPM)  Integrated communications co‑processor functionality for offload of protocol handling and serial communications tasks (listed as Communications; CPM in device specifications).
• Networking Interfaces  Two Ethernet interfaces: one 10 Mbps port and one 10/100 Mbps port, plus HDLC/SDLC support for framed serial data links.
• Memory Controller  On‑chip DRAM controller support to interface with external system memory.
• Power & I/O  3.3 V I/O signaling for compatibility with common embedded peripherals and board designs.
• Package & Mounting  357‑PBGA (25×25) supplier device package; surface mount package suitable for compact board layouts.
• Operating Range & Qualification  Rated for an operating temperature range of 0 °C to 95 °C and qualified to consumer product standards. RoHS compliant.

Typical Applications

• Communications Equipment  Suitable for controller and networking elements that require integrated Ethernet ports and CPM‑based protocol handling.
• Embedded Controllers  Use in dedicated controller applications where a compact single‑core PowerPC processor with DRAM controller is required.
• Networking Appliances  Ideal for small networking appliances and gateways that need 10/100 Mbps Ethernet plus legacy 10 Mbps connectivity and HDLC/SDLC support.

Unique Advantages

• Integrated Communications Offload: Built‑in CPM/co‑processor support reduces software overhead for protocol processing and serial communications.
• Balanced On‑Chip Memory Architecture: Combined instruction and data caches with MMU and TLB support improve deterministic performance for embedded workloads.
• Versatile Ethernet Configuration: Dual Ethernet ports (10 Mbps and 10/100 Mbps) provide flexible connectivity options for mixed‑speed network deployments.
• Compact Surface‑Mount Package: 357‑PBGA (25×25) packaging enables dense board layouts while maintaining the I/O and memory interfaces needed by embedded systems.
• RoHS Compliant: Environmentally compliant design supports regulatory requirements for modern electronics manufacturing.
