MPC860TCVR50D4 - 50MHz 32-Bit PowerQUICC MPU | NXP

The NXP Semiconductors MPC860TCVR50D4 is a 32-bit, single-core PowerQUICC microprocessor operating at 50 MHz in a 357-pin PBGA package. It is designed for communications and networking controller applications and is identified by the verified distributor data as an MPC8xx MPU with a 25 x 25 mm package, 3.3 V supply, and tray packaging. The MPC860 belongs to the PowerQUICC processor family, combining a RISC-oriented embedded processor core with communications-oriented peripherals in one integrated device. This category of processor is used when a system needs more control, memory access, and protocol flexibility than a small microcontroller provides, while retaining a dedicated communications architecture. The part is therefore positioned between basic microcontrollers and higher-end application processors for embedded infrastructure, control, and gateway equipment. Key verified attributes include a 50 MHz operating speed, 32-bit processor architecture, 0.32 micrometer process information listed in distributor data, and a 357-BBGA package. The available product records identify the part as an MPC8xx PowerQUICC processor and state that NXP describes it as delivering higher performance, greater integration, and lower power consumption than traditional architectures. Those statements are manufacturer descriptions, not independent benchmark results, and should be validated against the complete datasheet and application requirements. Typical design contexts include communications controllers, networking equipment, protocol conversion systems, embedded routers, gateways, and industrial communications platforms. The integrated processor and peripheral approach reduces the need for separate interface logic when the firmware is designed around the MPC860 architecture. Buyers should confirm memory interfaces, peripheral availability, electrical limits, package ball assignments, and software support against the specific product revision before committing to a design. A critical procurement consideration is lifecycle status. The NXP product page labels this part as End of Life, so new production availability should not be assumed. Engineers should check authorized distributor inventory, last-time-buy status, and any approved sourcing routes. For a replacement, require a detailed pin, electrical, firmware, and timing review rather than relying only on a distributor similarity label. This page consolidates verified distributor and manufacturer information, identifies package and sourcing risks, and separates confirmed values from parameters that still require datasheet confirmation for production design and procurement.

Architecturally, the device separates control-plane work (PowerPC core) from data-plane communication work (CPM), enabling concurrent protocol handling without burdening the main CPU. The CPM uses microcoded RISC engines (CP) and serial-interface controllers (SCC/SMC) to offload framing, CRC, and HDLC bit-stuffing tasks from the host CPU, reducing interrupt load in router/bridge/DSLAM designs. Typical applications include WAN routers, ISDN/ADSL modems, Ethernet bridges, industrial control and HMI controllers, and legacy telecom line cards. The PowerQUICC family is well documented in NXP/Freescale reference designs and the Green Hills INTEGRITY, VxWorks, and Linux (pre-2020 LTS) BSP ecosystems. When designing with this part, note that the device is now End-of-Life per NXP, with last-time-buy window passed. New designs should consider the PowerQUICC II (MPC82xx) or QorIQ families for forward compatibility, while existing hardware can be maintained with the part itself or with verified stock held by franchise distributors. This page aggregates distributor pricing (DigiKey 2026-10-16), drop-in alternative families from the MPC8xx product line, and practical design notes not consolidated in the original PowerQUICC hardware specifications manual.

MPC862PVR80B

MPC862PVR80B - 80MHz PowerQUICC MPC8xx MPU | NXP | BGA-357

The NXP (formerly Freescale/Motorola) MPC862PVR80B is a 32-bit PowerQUICC integrated communications processor (MPC8xx family) operating at 80 MHz, housed in a 357-ball PBGA package measuring 25 x 25 mm. It integrates a PowerPC core with the CPM (Communications Processor Module) and is fabricated on a 0.32 micrometer CMOS process with a 3.3 V core I/O supply. An MPU (Microprocessor Unit) in the PowerQUICC family combines a general-purpose PowerPC integer core with dedicated on-chip peripherals designed for networking and telecom equipment. The MPC8xx sits in the hierarchy above single-core MCUs and below higher-end PowerQUICC II/III devices, and it typically serves as the central controller in routers, bridges, and remote-access equipment where both RISC processing and serial-protocol offload are required. Key features include the 80 MHz core frequency, integrated CPM with support for multiple HDLC/SCC channels, 32-bit PowerPC architecture, and the 357-PBGA surface-mount package. The device integrates a 4-channel DMA controller, timers, a memory-management unit, and a 60x-compatible bus for external memory interfacing. Power consumption is dominated by the 3.3 V supply rail and scales with clock and CPM activity. Architecturally, the MPC862PVR80B separates control-plane processing from data-plane protocol handling: the PowerPC core runs the application stack while the CPM handles serial-channel DMA, HDLC framing, and ATM SAR. The 0.32 micrometer process gives reasonable static leakage for an embedded device of its era, and the 357-PBGA footprint provides ample ground/thermal balls for board-level dissipation. Typical applications include integrated access devices, LAN/WAN routers, frame-relay access equipment, xDSL modems, and industrial serial-control gateways. The combination of an embedded CPU plus the CPM makes it well suited to multi-protocol bridging tasks where a discrete CPU + ASIC solution would be too large. When designing with this MPU, plan the PCB for the 25 x 25 mm BGA land pattern with at least 6 layers to route the 60x bus cleanly, and pay attention to the 3.3 V supply decoupling near each power ball. Because the part is mature, source through franchised distributors or authorized aftermarket partners to mitigate counterfeit risk.

MPC862PZQ66B - 66MHz PowerQUICC MPU, 357-PBGA | NXP Semiconductors

The NXP Semiconductors MPC862PZQ66B is a 32-bit PowerQUICC microprocessor IC from the MPC8xx family, operating at a 66 MHz core clock speed and housed in a 357-ball Plastic Ball Grid Array (PBGA) measuring 25 x 25 mm. It integrates a single MPC8xx core with on-chip peripherals including a communications processor module (CPM), system integration functions, and memory controllers, all targeted at networking and telecom equipment that require deterministic multi-protocol serial handling on a single chip. A PowerQUICC (a portmanteau of PowerPC plus QUICC, where QUICC stands for Quad Integrated Communications Controller) is a category of embedded PowerPC microprocessors that pair a general-purpose CPU with a dedicated RISC-based communications processor. This dual-processor architecture offloads serial protocol handling (Ethernet, HDLC, ATM, UART, I2C, SPI) from the main CPU, enabling wire-speed data plane performance without over-provisioning the host core. Within the power management hierarchy, the MPU sits above voltage regulators and below the system-level integration logic. Key specifications include a 66 MHz maximum core frequency, 3.3 V typical I/O supply voltage, a 32-bit data path, and packaging compatible with industrial-grade operating ranges. The device is supplied in tray form, ships in a 357-ball PBGA (25 x 25 mm) footprint, and is qualified to NXP's standard product specifications for embedded networking applications. Architecturally, the MPC862PZQ66B couples a PowerPC core with the CPM, a separate RISC engine for serial channel management. This split allows the host CPU to run control-plane stacks while the CPM executes bit-level protocol work, achieving wire-rate multi-channel performance that single-core MPUs cannot match at the same clock. Memory interfaces support DRAM, SRAM, and Flash via a 32-bit system bus. Typical applications include ISDN terminal adapters, DSL access multiplexers, router control planes, industrial protocol bridges, and legacy telecom line cards. The integrated CPM makes it especially well-suited to multi-protocol serial aggregation where a smaller MCU plus discrete PHY would otherwise require additional glue logic. When designing with this device, allocate adequate PCB area for the 357-ball PBGA - the 1.27 mm (or finer) pitch requires 4-layer or higher stack-ups with microvia capability. Decouple the 3.3 V core/IO rails with bulk plus high-frequency ceramics within 5 mm of the ball array, and follow NXP's routing rules for the system bus to avoid signal-integrity violations on parallel memory interfaces.

MPC866TZP133A - MPC8xx PowerQUICC 133MHz BGA Processor | NXP

The NXP (formerly Freescale/Motorola) MPC866TZP133A is a PowerQUICC communications processor from the MPC8xx family, integrating a 32-bit Power Architecture core running at 133 MHz with a dedicated Communications Processor Module (CPM) in a 357-pin PBGA (25x25 mm) package. It features a 0.18 µm CMOS process, a 1.8 V core supply, 3.3 V I/O with 5 V TTL tolerance, and a 66 MHz external bus. The MPC866 is a 0.18 µm shrink of the proven MPC862 PowerQUICC architecture, adding Enhanced SAR (ESAR) ATM support. What is a PowerQUICC processor? PowerQUICC is a family of integrated communications processors that combine a Power Architecture CPU core with a dedicated Communications Processor Module (CPM) for protocol handling. The hierarchy is: PowerQUICC -> communications processor -> microprocessor (MPU) -> integrated circuit -> semiconductor. By offloading bit-level protocol work (Ethernet, ATM, HDLC, UART) into the CPM, the core is freed for control-plane software, which is why PowerQUICC parts dominated telecom routers, DSLAMs, and PBX equipment. The MPC866 family adds several differentiating capabilities over the MPC860/862. Enhanced SAR (ESAR) mode provides improved ATM Operation, Administration and Maintenance (OAM) support, OAM Performance Monitoring, and multiple APC priority levels for QoS-aware traffic shaping. Four 10/100 Mbps Ethernet interfaces, two 10 Mbps Ethernet MACs, serial ATM, HDLC, transparent, and UART channels are supported by the CPM, enabling multi-port bridge/router designs without external PHY/mac ASICs. The part operates from a 1.8 V core and 3.3 V I/O supply, with 5 V TTL-tolerant inputs on peripheral pins, easing migration from legacy 5 V logic. Memory controller hardware supports DRAM (up to 16 banks), SRAM, EPROM, Flash, and a 32-bit data bus with parity, allowing direct attachment of external program and packet memory. The device is specified over 0 °C to 95 °C ambient (commercial grade), making it suitable for controlled-environment networking and industrial platforms. Typical applications include multi-port 10/100 Ethernet routers, xDSL CPE/DSLAM line cards, ISDN PRI/BRI gateways, T1/E1 channel banks, industrial control with serial networking, and legacy telecom backplane processor boards. The integrated CPM dramatically reduces bill-of-materials cost versus a CPU + external MAC/PHY approach. When designing with the MPC866TZP133A, pay close attention to the 357-ball PBGA escape routing: the 1.0 mm ball pitch demands 4-layer or better PCBs with microvia stackups, and a solid GND plus split 1.8 V/3.3 V power plane is required. Decouple each Vdd/Vss pair with 0.1 µF and 10 µF capacitors placed within 3 mm of the balls. For new designs, also evaluate the MPC8360/MPC8313 successors and verify longevity/support status, as MPC8xx is in long-term support rather than active release.

A PowerQUICC processor is a system-on-chip communications controller that integrates a Power Architecture CPU with flexible peripheral interfaces such as serial, Fast Ethernet, ATM, and time-division multiplexed channels. Historically, the MPC8xx family was the first PowerQUICC generation, designed to consolidate the CPU, memory controller, and communication peripherals into a single IC, reducing BOM cost and board area in routers, DSLAM line cards, and industrial control platforms. The MPC87x series specifically targets low-cost, low-power communications designs that need Power Architecture performance without the higher clock speeds of the MPC860/MPC866 family. Key features of the MPC870VR66-FR include the 32-bit Power Architecture core running at 66 MHz, an integrated memory controller supporting DRAM, SRAM, ROM, and Flash, a communications processor module (CPM) that offloads serial and networking tasks from the CPU, and a flexible bus architecture with 16 KB of internal cache. The 256-PBGA package supports the wide address and data buses plus the CPM peripheral pins while remaining surface-mountable on standard 1.27 mm-pitch PCB land patterns. Typical applications include integrated access devices (IADs), residential gateways, SOHO routers, industrial serial-to-Ethernet bridges, and legacy telecom line cards where Power Architecture code compatibility is required. The part is also used in renewable energy inverter controllers, building automation, and factory-floor protocol converters that benefit from its deterministic interrupt response and on-chip peripherals. When designing with this device, pay close attention to the dual-voltage power tree (3.3 V I/O and 1.8 V core), provide proper decoupling on every supply pin pair, and ensure PCB layout follows BGA escape routing best practices with matched impedance on the address and data bus groups. The internal CPM can be used to run HDLC, UART, or Fast Ethernet MAC protocols, freeing the core for higher-layer processing.
