MPC860DPZQ66D4

The MPC860DPZQ66D4 is a single-core, 32-bit microprocessor in the MPC860 PowerQUICC family, offering a 66 MHz CPU and integrated communications-oriented peripherals. It is designed for embedded and communications controller applications, where integrated I/O and networking interfaces reduce system complexity.

Built around Power Architecture technology, the MPC860 family combines the CPU core with on-chip peripheral resources—including a communications processor module (CPM) and enhanced memory controller—making this device suitable for consumer-grade networking and embedded communications designs.

Key Features

• Core – Single 32-bit MPC8xx core running at 66 MHz, implementing Power Architecture technology for embedded control and communications tasks.
• Memory and MMU – On-chip memory management support and family-level instruction/data cache architecture as described for the MPC860 PowerQUICC family; enhanced memory controller supports DRAM types.
• Co-processor / CPM – Integrated Communications Processor Module (CPM) for communications offload and protocol handling.
• Ethernet – Multiple Ethernet interfaces: two 10 Mbps ports and one 10/100 Mbps port for mixed-speed network connectivity.
• Interfaces – Additional serial protocol support including HDLC/SDLC; PCMCIA socket controller capability is included in the MPC860 family.
• Power / I/O – 3.3 V I/O voltage, suitable for common embedded I/O domains.
• Package and Mounting – 357-pin PBGA package (357-PBGA, 25×25 mm) in a surface-mount form factor.
• Operating Range – Consumer qualification with an operating temperature range of 0 °C to 95 °C.
• Environmental – RoHS compliant.

Typical Applications

• Embedded Networking Equipment – Use the integrated Ethernet ports and CPM to implement packet handling and network control in consumer networking products.
• Communications Controllers – Ideal for controller applications that require a dedicated communications processor and serial protocol support such as HDLC/SDLC.
• PCMCIA-Enabled Designs – Deploy in systems requiring on-board PCMCIA socket control and DRAM support as found in the MPC860 family documentation.
• Consumer Embedded Systems – Suited to consumer-grade products that need compact PBGA packaging, 3.3 V I/O, and operation across typical consumer temperature ranges.

Unique Advantages

• Integrated Communications Subsystem: The on-chip Communications Processor Module (CPM) and serial protocol support reduce external component count and simplify board design for networking applications.
• Multiple Ethernet Interfaces: Two 10 Mbps ports plus one 10/100 Mbps port provide flexible connectivity options for mixed-speed networks without additional PHYs.
• Enhanced Memory Support: Family-level enhancements to the memory controller enable use with DRAM, allowing designers to provision system memory to match application requirements.
• Compact Surface-Mount Package: The 357-PBGA (25×25) package supports high-density PCB layouts while maintaining a robust pin count for peripheral connectivity.
• Industry-Standard I/O Voltage: 3.3 V I/O compatibility aligns with common embedded peripherals and interface standards.
• RoHS Compliant: Conforms to environmental compliance expectations for consumer electronics manufacturing.
