MPC860TZQ50D4

The MPC860TZQ50D4 is a single-core, 32-bit microprocessor from NXP Semiconductors’ MPC860 PowerQUICC family, operating at 50 MHz. It implements Power Architecture technology and integrates communications-oriented peripherals to address embedded controller and networking applications.

Designed for communications and controller use, the device combines a Power Architecture CPU with a Communications Processor Module (CPM), DRAM interfacing, multiple Ethernet ports and common serial protocols to simplify system-level integration.

Key Features

• Core – Single 32-bit MPC8xx core operating at 50 MHz with memory management units and instruction/data caches as part of the MPC860 family architecture.
• Memory and Controllers – Integrated DRAM controller to support external memory; MMU and instruction/data caches for efficient code and data handling.
• Communications & CPM – Communications co-processor (CPM) for protocol handling; series documentation notes inclusion of an inter-integrated controller (I2C) channel and support for communications processing.
• Serial Protocols – Additional interfaces include HDLC/SDLC for serial link framing and protocol support.
• Ethernet – Multi-port Ethernet capability: four 10 Mbps ports and one 10/100 Mbps port, suitable for embedded networking tasks.
• Package and Mounting – 357-ball PBGA package (357-PBGA, 25×25) in a surface-mount form factor.
• Power and I/O – I/O voltage at 3.3 V to match common embedded system power rails.
• Operating Conditions & Qualification – Consumer-qualified device with an operating temperature range of 0 °C to 95 °C.
• Environmental Compliance – RoHS compliant.

Typical Applications

• Communications and Networking Equipment – Suitable for embedded gateways, controllers and networked appliances requiring integrated Ethernet and protocol processing.
• Embedded Controller Systems – Single-core 32-bit processing with DRAM support and MMU/cache makes it applicable to control-oriented embedded designs.
• PCMCIA and Card-Based Interfaces – MPC860 series documentation indicates PCMCIA socket controller support, enabling use in systems that require removable-card connectivity.

Unique Advantages

• Highly integrated communications support: CPM plus HDLC/SDLC interfaces and multiple Ethernet ports reduce external protocol hardware and simplify board-level design.
• Power Architecture processing with MMU and caches: On-chip MMU and instruction/data caches improve software execution efficiency for embedded workloads.
• Flexible memory interfacing: Built-in DRAM controller supports a range of memory types to match system performance and capacity needs.
• Compact PBGA footprint: 357-PBGA (25×25) surface-mount package enables dense PCB layouts for space-constrained designs.
• RoHS compliant and consumer qualified: Meets environmental compliance requirements and is specified for consumer-grade operating conditions.
