MPC875VR80 - 80MHz 32-Bit PowerQUICC MPU | NXP
部品番号: MPC875VR80 ✗ 生産終了MPC875VR80 概要
A communications processor or MPU is a semiconductor category that combines a processor core, memory-management hardware, interfaces, and communication peripherals in one integrated device. The MPC875 belongs to the PowerQUICC communications-processor hierarchy, which combines the Power Architecture core with communications-oriented peripherals. This architecture is intended for embedded networking, industrial communication, and data-processing systems that need more peripheral integration than a general-purpose microcontroller provides.
Key verified features include a 32-bit data bus, a maximum clock frequency of 80 MHz, and a 0.18 µm process generation. The processor includes memory-management units and instruction and data caches according to the NXP MPC875/MPC870 hardware specification. Its MPC8xx communications role allows networking functions to share a single device with real-time control workloads while reducing component count compared with a discrete processor-plus-interface design.
The MPC875 architecture combines a 32-bit Power Architecture core with the MPC8xx communications peripheral set. Its caches support faster access to frequently used instructions and data, while the memory-management units provide the address translation and protection needed by modern embedded operating systems. The exact cache sizes, bus timing values, memory-interface details, and operating-current figures require the complete NXP hardware specification and are therefore not inferred from distributor summaries.
Typical applications include industrial routers, communication line cards, network bridges, protocol converters, embedded gateways, and control systems that process serial data alongside network traffic. In these systems, the processor can manage communication tasks and peripheral data movement while providing a single-chip implementation of communications-oriented control. The exact hardware interfaces and supported protocols must be confirmed against the complete manufacturer datasheet before schematic capture.
The most important design consideration is package and software continuity. The MPC875VR80 uses a 256-ball PBGA footprint with fine-pitch routing, so PCB layout, assembly capability, thermal management, and BGA inspection must be planned early. Designers should also verify the required firmware, driver, toolchain, and operating-system support because software compatibility can be as restrictive as electrical compatibility when replacing an older communications processor.
This page consolidates the verified NXP device identity, distributor availability context, package information, lifecycle caveats, and engineering-focused comparison guidance. It also distinguishes documented drop-in candidates from broader functional alternatives, helping procurement and design teams evaluate PCB, software, and supply risks without treating every similar communications processor as interchangeable.

主な用途
MPC875VR80 の用途: 6 件s: Industrial Communication Gateway, Network Router and Line Card Control, Protocol Converter, Embedded Network Control System, Data Acquisition and Serial Processing Unit, Legacy Communication Equipment Controller.
Industrial Communication Gateway
The MPC875VR80 fits an industrial communication gateway that must coordinate protocol processing, serial-data handling, and real-time control from one processor. Its 32-bit Power Architecture core operates at up to 80 MHz, providing more arithmetic capacity than an 8-bit MCU while integrating the communications-oriented features associated with the MPC8xx family. The device can sit between physical network interfaces and an application processor or supervisory controller. This integration reduces board partitioning, but engineers must confirm the required serial, Ethernet, memory, and DMA resources in the NXP hardware specification. The 256-ball PBGA also requires a PCB and assembly process capable of handling fine-pitch BGA routing and inspection.
おすすめ
Network Router and Line Card Control
The MPC875VR80 is appropriate for a router, bridge, or communication line card that needs an 80 MHz 32-bit processor for packet-oriented control and communications tasks. The MPC8xx communications-processor positioning supports embedded networking designs where deterministic control, memory management, caches, and multiple peripherals must operate together. Compared with a simple microcontroller, the processor provides a wider 32-bit computational path and a larger integration opportunity. Actual Ethernet or serial interface selection remains design-specific and must be checked against the complete NXP document. Validate protocol firmware, driver availability, memory timing, and thermal performance before committing the legacy BGA package to a new production design.
おすすめ
Protocol Converter
A protocol converter can use the MPC875VR80 to translate traffic between equipment interfaces while buffering and routing data through an embedded operating-system or real-time control environment. Its 80 MHz clock and 32-bit Power Architecture core suit communication-intensive workloads that require more processing headroom than a basic control MCU. The processor also supports memory management and instruction and data caches, which are useful when running modular gateway software. Because exact protocol engines and bus interfaces are not exposed in the retrieved excerpts, the complete datasheet must be consulted to confirm that every required interface is native. Software porting effort should be evaluated alongside pin and clock compatibility.
おすすめ
Embedded Network Control System
The MPC875VR80 can serve as the central controller in an embedded network system that combines communications handling, supervisory logic, and real-time I/O control. The 3.3 V device and 0°C to 95°C stated operating range permit use in controlled industrial environments, although the system must provide suitable power regulation and thermal design. The 32-bit data bus and 80 MHz clock are more than sufficient for many supervisory tasks, provided the external memory interface and I/O requirements are confirmed. Designers should also verify device identity, boot behavior, firmware support, and peripheral mappings before treating an MPC8xx ordering variant as a functional replacement.
おすすめ
Data Acquisition and Serial Processing Unit
The MPC875VR80 is suited to a data-acquisition unit that must process serialized sensor or equipment data while handling communications and control tasks in parallel. Its single-core, 32-bit architecture at up to 80 MHz provides a practical balance of processing capability and integration for legacy embedded equipment. Memory-management units and instruction and data caches can support larger firmware environments than a small microcontroller. The exact bus widths, cache capacities, DMA behavior, and electrical timing are not included in the verified excerpts and must not be inferred. System planning should include sustained processing load, BGA assembly yield, thermal rise, and long-term software-maintenance requirements.
おすすめ
Legacy Communication Equipment Controller
The MPC875VR80 can be retained in legacy communication equipment where established PowerQUICC firmware, board layouts, and peripheral assignments already exist. Its 80 MHz 32-bit Power Architecture core is specifically associated with the MPC8xx communications-processor generation, making it a practical continuity choice for systems originally designed around this device family. The 256-ball PBGA footprint limits straightforward migration because few modern boards offer that land pattern. Replacement work must compare ball assignments, power pins, reset behavior, clock requirements, memory interfaces, and software configuration. Inventory provenance, date codes, and long-term supply plans should be addressed before this legacy architecture is extended into a new deployment.

設計ノート
Treat the 256-ball PBGA as a constrained fine-pitch layout rather than a generic BGA footprint. Preserve the ball map, power distribution, and escape routing from the approved NXP reference design, and confirm the PCB fabricator's BGA capability, pad definition, solder-mask policy, and inspection method before layout release. A visually similar package is not sufficient evidence of drop-in compatibility.
Use the complete NXP hardware specification to establish supply voltage tolerance, sequencing, input impedance, and current limits. The verified data confirms a 3.3 V device but does not expose operating-current or absolute-maximum values, so regulator selection and power estimation must not rely on the distributor summaries. Decouple each applicable supply group according to the manufacturer recommendation and validate steady-state and transient behavior on hardware.
The processor is specified from 0°C to 95°C, but that range is environmental and does not establish safe internal die temperature. Measure or calculate junction rise using the actual board construction, airflow, processor activity, and supply voltage. Because the verified excerpts omit thermal resistance and current limits, use the complete manufacturer electrical specification rather than estimating dissipation from processor frequency alone.
Do not assume that an MPC8xx family member with the same 256-ball package is electrically and software interchangeable. Compare the device ID, clock maximum, ordering suffix, temperature grade, supply pins, reset behavior, memory and communications interfaces, and boot configuration. Also validate compiler, debugger, operating-system, and driver availability because legacy software support can prevent an otherwise credible hardware substitution.
