MPC862PCZQ80B

The MPC862PCZQ80B is a single‑core, 32‑bit microprocessor in the MPC8xx family built around a PowerPC™ architecture core running at 80 MHz. Designed for embedded and communications applications, the device integrates processor, memory controller and communications co‑processing features to support networking and controller systems.

This device targets embedded control and communications markets, offering on‑chip connectivity options and DRAM controller support while operating with 3.3 V I/O and a compact 357‑PBGA (25 × 25 mm) surface‑mount package.

Key Features

• Core: Embedded single‑issue 32‑bit MPC8xx PowerPC core operating at 80 MHz, providing standard PowerPC architectural features for embedded processing.
• Caches and MMU (MPC862P variant): Family documentation indicates the MPC862P variant includes a 16‑Kbyte instruction cache and an 8‑Kbyte data cache, with MMUs that provide 32‑entry fully associative instruction and data TLBs and multiple supported page sizes.
• Communications Co‑processor (CPM): Integrated communications processing capabilities suitable for offloading protocol and I/O tasks in networking and telecom designs.
• Memory Controller: On‑chip DRAM controller support to simplify external memory interfacing for embedded applications.
• Ethernet Connectivity: Multiport Ethernet support as indicated for the family: four 10 Mbps ports and one 10/100 Mbps port, enabling diverse networking topologies.
• Voltage and Mounting: 3.3 V I/O signaling and surface‑mount 357‑PBGA (25 × 25 mm) package for compact board integration; supplied in tray packaging.
• Integration for Networking: Family features include enhanced ATM functionality and a range of peripheral timing and bus interfaces described in the MPC862 family documentation.

Typical Applications

• Networking Equipment: Suitable for routers, switches and edge devices where integrated Ethernet ports and communications co‑processing reduce external controller load.
• Telecommunications Systems: Applicable in telecom endpoints and access equipment leveraging the family’s enhanced ATM and communications processing capabilities.
• Embedded Controllers: Useful in general embedded controller roles requiring a PowerPC core, DRAM support and integrated peripheral handling.
• Industrial Networking: Fits industrial networking nodes that require deterministic control and multiple Ethernet interfaces in a compact package.

Unique Advantages

• Integrated PowerPC Core: A single 32‑bit MPC8xx PowerPC core provides a familiar architecture for embedded developers and toolchains.
• On‑Chip Communications Offload: The CPM communications co‑processor reduces host CPU overhead for protocol processing, simplifying real‑time networking tasks.
• Multiple Ethernet Interfaces: Built‑in support for multiple Ethernet ports enables direct connection to network links without extensive external logic.
• DRAM Controller Included: Integrated DRAM controller streamlines memory subsystem design and reduces BOM complexity.
• Compact Surface‑Mount Package: 357‑PBGA (25 × 25 mm) package allows dense board layouts while maintaining necessary I/O and thermal considerations.
