MPC860DTCZQ50D4

The MPC860DTCZQ50D4 is a single-core 32-bit microprocessor from NXP Semiconductors’ MPC860 PowerQUICC family, provided in a 357‑PBGA (25×25) surface-mount package. It operates at 50 MHz with 3.3 V I/O and is qualified for industrial temperature operation.

Designed as an integrated microprocessor and peripheral solution, the MPC860 combines a Power Architecture™‑based CPU with a communications processor module and enhanced memory controller, targeting communications, networking and embedded industrial applications that require on‑chip I/O and protocol handling.

Key Features

• Core & architecture – MPC8xx 32‑bit core built on Power Architecture™ technology; includes memory management units (MMUs) and instruction/data caches as part of the MPC860 family hardware specifications.
• Clock performance – 50 MHz operating frequency suitable for embedded communications control and system tasks.
• Power & I/O voltage – 3.3 V I/O signaling for compatibility with common embedded interfaces.
• Communications Processor Module (CPM) – Integrated CPM for communications offload and protocol handling, with support for HDLC/SDLC and additional serial interfaces.
• Ethernet connectivity – On‑chip Ethernet support: two 10 Mbps ports and one 10/100 Mbps port for networked applications.
• Memory and expansion – Enhanced memory controller supporting DRAM and on‑chip PCMCIA socket controller functionality (family specification supports up to two PCMCIA sockets).
• Package & mounting – 357‑PBGA (25×25) supplier device package; surface mount for compact board integration.
• Industrial qualification & temperature – Qualified for industrial use with an operating temperature range of −40 °C to 95 °C; RoHS compliant.
• Integrated peripherals – Family documentation notes inclusion of real‑time clock and various bus interfaces to support embedded system requirements.

Typical Applications

• Networking equipment – Use in routers, switches or edge devices that require multiple Ethernet ports and integrated communications handling.
• Communications controllers – Ideal for protocol offload and serial/HDLC link management where the CPM and HDLC/SDLC interfaces reduce host CPU load.
• Industrial control systems – Industrial‑rated operation and wide temperature range make it suitable for automation controllers and field gateways.
• Embedded gateways – Compact PBGA package and on‑chip memory/controller functionality support small form‑factor gateway designs.

Unique Advantages

• Highly integrated communications stack – On‑chip CPM plus Ethernet ports and HDLC/SDLC interfaces reduce external component count and simplify board design.
• Power Architecture-based CPU with MMU and caches – Built-in MMUs and instruction/data caches (per family documentation) support efficient code execution and system performance.
• Industrial-grade reliability – Industrial qualification and −40 °C to 95 °C operating range enable deployment in demanding environments.
• Flexible memory support – Enhanced DRAM controller and PCMCIA socket controller capability provide options for system memory and expansion.
• Compact package for dense designs – 357‑PBGA (25×25) package supports space‑constrained, surface‑mount assemblies.
• Documented hardware specifications – Comprehensive family hardware specifications and published documentation support design, thermal and electrical planning.
