MPC860PZQ66D4

MPC860PZQ66D4 - 66MHz PowerQUICC MPU, 357-BGA | NXP

The NXP MPC860PZQ66D4 is a 32-bit PowerQUICC microprocessor from the MPC8xx family, integrating a PowerPC core with a communications processor module (CPM) for networking and telecom applications. It runs at 66 MHz, operates from a 3.3 V supply, and is housed in a 357-ball plastic BGA (PBGA, 25x25 mm) package. The 'P' designator identifies the full-featured PowerQUICC configuration with both Ethernet and HDLC/serial support, while 'ZQ' denotes the 357-PBGA package and '66' the 66 MHz CPU clock. The trailing 'D4' indicates the silicon revision and operating temperature grade. Background Knowledge: A microprocessor (MPU) is an integrated circuit that contains the central processing unit of a computer system, executing instructions fetched from external memory. The PowerQUICC architecture merges a general-purpose PowerPC processor core with dedicated on-chip peripherals (communications processor module, memory controller, timers, serial interfaces) so a single chip can manage both control-plane software and real-time data-plane I/O. This hypernym hierarchy runs: MPU -> embedded processor -> communications processor -> system-on-chip. The MPC8xx family is the legacy predecessor to today's QorIQ and Layerscape product lines, but remains specified for long-lifecycle industrial and telecom designs. Key features include a 32-bit PowerPC core, integrated CPM with multiple SCCs (serial communication controllers), Ethernet MAC, HDLC support, four 16-bit timers, a DRAM controller, and an interrupt controller. The 357-PBGA package provides high pin density for the rich peripheral set and is rated for industrial temperature operation. The 'D4' silicon revision brings refined power management relative to earlier revs. The architecture combines a RISC-style PowerPC integer unit with a dedicated CPM that offloads communications DMA, enabling wire-speed serial handling without burdening the core. The 3.3 V I/O and internal logic simplify mixed-voltage designs in legacy 3.3 V systems, though level shifters are required for 5 V peripherals. Typical applications include telecom line cards, ISDN routers, xDSL modems, industrial Ethernet switches, and embedded control systems requiring integrated serial-channel management. The combined core-plus-CPM topology makes the MPC860PZQ66D4 well suited to designs where deterministic serial throughput and CPU-driven control share the same silicon. When designing with this part, allocate the BGA's thermal pad with multiple inner-plane vias and use a four-layer PCB with a solid ground pour to dissipate the ~2 W typical dissipation. Verify boot-mode configuration resistor strapping against the datasheet before layout finalization, and ensure the 60x bus interface timing budget is met under worst-case loading. Note that this part is in End-of-Life status; design new production with an active QorIQ successor in mind.

MPC860PZQ66D4-FR - 66MHz PowerQUICC MPU, 357-PBGA | NXP
MPC860PZQ66D4-FR

MPC860PZQ66D4-FR - 66MHz PowerQUICC MPU, 357-PBGA | NXP

The NXP MPC860PZQ66D4-FR is a PowerQUICC MPC8xx family 32-bit microprocessor running at 66 MHz, integrating a PowerPC core with a communications processor module (CPM) for high-performance networking and telecom controller applications. Housed in a 357-ball PBGA (25x25 mm) package and supplied from a 3.3 V rail, the device combines a RISC CPU, dual UART, SCC/SMC serial channels, I2C, SPI, and a 10/100 Ethernet MAC into a single chip. The part ships in tray packaging with lead-free ("FR") solder finish. A PowerQUICC (pronounced "power-quick") is a family of integrated communications processors that fuses a PowerPC integer unit with a specialized RISC-based Communications Processor Module. This dual-engine architecture lets the CPM handle low-level serial framing, DMA, and protocol termination while the CPU runs the application and control plane. PowerQUICC devices belong to the broader category of embedded microprocessors (MPU), sitting above general microcontrollers (MCU) in integration level because they include dedicated communications peripherals, memory controllers, and external bus interfaces rather than relying solely on internal flash. Key features of the MPC860PZQ66D4-FR include a 32-bit PowerPC core with separate instruction and data caches, four baud-rate generators, a 10/100 Mbps Fast Ethernet controller, support for up to eight SCC (Serial Communications Controller) channels, four SMC (Serial Management Controller) channels, an I2C controller, an SPI interface, a PCMCIA interface, and a 32-bit external bus interface. The CPM off-loads DMA and protocol handling from the CPU, freeing the core for routing, control, and management tasks. Architecture depth: the MPC860 uses a 0.32 micron CMOS process and integrates an integer PowerPC unit with an embedded RISC controller inside the CPM. This dual-core topology delivers deterministic serial performance while keeping CPU load low - critical for router, bridge, and DSLAM designs where throughput and latency matter more than raw clock speed. The part supports both single- and multi-PHY Ethernet configurations through its Media Independent Interface. Typical applications include ISDN router and remote access server designs, DSLAM line cards, Ethernet-to-Serial bridge gateways, industrial protocol converters, and legacy telecom equipment. The wide CPM peripheral set also suits SCADA concentrators, factory-floor protocol routers, and PBX interface cards. Designers usually pair the MPU with external SDRAM, Flash, and PHY devices. When designing with this part, pay close attention to power sequencing: 3.3 V I/O must come up before or simultaneous with the 2.5 V core voltage, and the HRESET must remain asserted until both rails stabilize. PCB layout requires a minimum of 4 PCB layers with continuous ground and power planes directly under the PBGA to keep impedance-controlled traces for the address/data bus clean.

It integrates a PowerPC embedded core with a system integration unit, communications processor module (CPM), and a full peripheral set including Ethernet, serial, and PCMCIA controllers. A PowerQUICC microprocessor (often abbreviated MPU or comms processor) is a specialized integrated processor that combines a general-purpose embedded CPU with a dedicated communications engine on a single die. Within the broader taxonomy it is a microprocessor -> embedded processor -> integrated communications controller -> PowerQUICC family -> MPC8xx sub-family. The CPM offloads serial, ATM, and Ethernet processing from the main core, freeing CPU cycles for protocol stacks such as TCP/IP, HDLC, and PPP, which made the PowerQUICC architecture a workhorse for routers, switches, and telecom equipment in the late 1990s and 2000s. Key differentiating specifications include the 80 MHz core clock, the integrated 10/100 Mbps Ethernet MAC (Fast Ethernet), dual serial communications controllers (SCCs) plus four serial management controllers (SMCs), a PCMCIA host adapter, and the 357-ball PBGA package. The device operates from a 3.3 V supply with a typical internal core voltage of approximately 2.2 V generated by an on-chip regulator. An external bus can address up to 8 MB of memory-mapped space per memory controller, and the part supports 8-, 16-, and 32-bit ROM/Flash/SRAM peripherals. Architecturally the MPC860PZQ80D4 uses a 0.32 micrometer CMOS process and pairs the embedded PowerPC core with the CPM (Communications Processor Module). The CPM contains its own microsequencer, dedicated serial channels, and time-division multiplexing support, achieving wire-speed handling of multiple serial protocols without CPU intervention. The 357 PBGA provides ample thermal headroom and signal integrity for industrial temperature (-40C to +95C) operation. Typical applications for the MPC860PZQ80D4 include enterprise and industrial routers, remote-access concentrators, ISDN modem banks, telecom control planes, and legacy networking line cards where the integrated CPM replaces external ASICs. It is also used in industrial serial-protocol gateways and in long-lifecycle defense and aerospace programs that require a stable, mature embedded communications controller. When designing with this part, verify supply availability early: NXP has formally classified this product family as End of Life and offers recommended replacement guidance on the NXP product page. Original PBGA layout, BIOS/firmware, and JTAG tooling should be retained for any board that may need to be re-qualified with a successor device.

It is the PowerQUICC I family member targeted at communications and networking controller designs. A PowerQUICC device is a system-on-chip that pairs a Power Architecture RISC microprocessor with a dedicated communications processor module. Within the semiconductor hierarchy it sits under embedded microprocessors, under 32-bit SoCs, under integrated circuits. The CPM offloads serial communications (SCCs, SMCs, SPI, I2C) from the core, which is why the MPC860 family became a standard building block for routers, bridges and industrial gateways. Key features include an 80 MHz PowerPC core with 4 KB instruction and 4 KB data caches, an integrated memory controller supporting DRAM, SRAM and ROM, a 32-bit data bus, and multiple serial communication channels. The device integrates Ethernet, ATM and HDLC protocol engines plus a PCMCIA interface, reducing external glue logic in networking designs. The MPC860 uses a dual-processor architecture: the embedded PowerPC core executes application code while the CPM handles protocol processing in parallel. This partitioning delivers deterministic communications throughput without burdening the core, a design pattern still used in modern network SoCs. Typical applications include industrial network routers and protocol converters, telecom line cards and remote access servers, and legacy industrial control gateways that require HDLC or ATM connectivity. The 357-pin PBGA package and 0 to 95 C temperature range suit board-level designs in controlled environments. When designing with this device, verify power sequencing and decoupling for the core and I/O rails, and confirm the exact part-number suffix because the MPC860 family spans multiple speed, temperature and revision variants that are not always interchangeable. This page synthesizes distributor availability, drop-in family alternatives, and practical design notes that are not consolidated in the manufacturer hardware specification, helping engineers evaluate the MPC860PZQ80D4557 for legacy and maintenance designs.

Technically, the device achieves its 80MHz core clock from an external oscillator multiplied by an on-chip PLL, and integrates 4KB of instruction cache and data cache, plus a separate CPM RISC engine for protocol acceleration. The CPM offloads protocol processing from the main core, enabling simultaneous Ethernet, HDLC, and ATM traffic without CPU saturation. The 357-pin PBGA package exposes a full 32-bit external address/data bus plus dedicated communications and memory controller pins. Typical applications include ISDN router control planes, xDSL modem CPE platforms, T1/E1 multiplexer control, industrial serial-to-Ethernet gateways, factory-floor protocol converters, and legacy telecom line-card management. The integrated CPM and Ethernet make the MPC860PZQ80D4R2518 well-suited for designs where a single IC must handle both packet processing and supervisory control. When designing with this part, allocate generous PCB area around the 357-pin PBGA for fanout, place a 4-layer minimum stackup with dedicated power and ground planes, and follow NXP AN-2120 layout guidance for PowerQUICC BGA thermal management. The device requires a 3.3V core supply plus 5V I/O and a low-jitter system clock for Ethernet PHY synchronization.

It operates at a 66 MHz core clock and is housed in a 357-pin PBGA (25x25 mm) package with a 3.3 V supply rail. A microprocessor (MPU) is a single-chip CPU that fetches, decodes, and executes instructions from external memory, serving as the central processing unit of an embedded system. The MPC8xx family is a 32-bit RISC microprocessor family integrating on-chip peripherals (SCC, FCC, SMC, SPI, I2C, timers) and a CPM, placing it within the broader hierarchy: microprocessor -> embedded processor -> communications controller -> power management controller -> semiconductor. This high level of integration is what made the PowerQUICC platform the de-facto controller for routers, DSLAMs, and base stations in the late 1990s and early 2000s. Key specifications include a 66 MHz CPU clock, 3.3 V I/O and core voltage, on-chip CPM with multiple serial channels, a 32-bit PowerPC core with MMU and unified caches, and a 357-ball plastic BGA package in a 25x25 mm footprint. The device integrates Ethernet (10/100), HDLC/SDLC, transparent and synchronous UART, and ATM support through the CPM, eliminating the need for an external protocol-handling ASIC. Technically, the MPC860SRCVR66D4 separates processing between the PowerPC core and the CPM, which handles DMA-driven peripheral traffic autonomously; the core is interrupted only when protocol-level frames are reassembled. The 0.32 um CMOS process delivers the low power dissipation that embedded telecom designs required at the time, and the 32-bit PowerPC ISA delivers predictable performance for RTOS workloads such as VxWorks, pSOS, and Linux derivatives. Typical applications include enterprise routers and access multiplexers, ISDN/DSL modem banks, telecom switching control boards, industrial serial-to-Ethernet gateways, and legacy SCADA controllers. Designers chose the MPC860SRCVR66D4 for its combination of deterministic CPM behaviour, mature toolchain support, and long-life revision control in industrial programs. Design considerations include careful BGA fan-out on a multi-layer PCB, decoupling on all VDD/VSS pairs, JTAG boundary-scan support for production test, and operating temperature choice tied to system airflow. For new designs consider the MPC8309 or LS1021 - the MPC860SRCVR66D4 is now in NRND / End-of-Life and should be qualified against the PCN before long-term production.

MPC860SRVR66D4 - 66MHz PowerQUICC MPU, 357-BGA | NXP

The NXP MPC860SRVR66D4 is a 32-bit PowerQUICC microprocessor from the MPC8xx family, integrating a PowerPC core with a communications processor module (CPM) and running at 66 MHz. Housed in a 357-ball plastic BGA (PBGA, 25 mm x 25 mm), this MPU targets embedded telecom, industrial control, and networking applications where deterministic I/O and on-chip peripheral integration reduce system BOM. Operating voltage is 3.3 V with 5 V tolerant I/O on selected interfaces per the NXP MPC860 family datasheet. An MPU (Microprocessor Unit) in the PowerQUICC family combines a general-purpose processor core with dedicated communication peripherals on a single die, eliminating the need for a companion ASIC or coprocessor. The MPC8xx sits in the broader taxonomy as a 32-bit embedded microprocessor -> embedded MPU -> PowerPC architecture -> communication-centric SoC. By co-integrating fast communication controllers (FCC, SCC, SMC, SPI, I2C), the MPC860 enables designs such as ISDN modems, routers, and protocol converters at lower system cost than discrete-ASIC solutions. Key features include 4 Kbytes of instruction cache, 4 Kbytes of data cache, a multiply-accumulate (MAC) unit for DSP-like operations, a memory management unit (MMU), and a system integration module (SIU). The CPM provides independent RISC-driven serial channels, supporting HDLC, transparent, and UART modes. An IEEE 1149.1 JTAG interface and on-chip debug port simplify boundary-scan test and in-system software development. Industrial-grade temperature range (-40C to +95C ambient) and a 0.32-micron CMOS process suit thermally constrained enclosures.

MPC860SRZQ66D4557 - PowerQUICC 32-bit MPU, 66 MHz | NXP

The NXP (formerly Freescale/Motorola) MPC860SRZQ66D4557 is a 32-bit PowerQUICC integrated communications controller microprocessor running at 66 MHz, housed in a 357-ball BGA package (ZQ suffix). It integrates a PowerPC core with the CPM (Communications Processor Module), making it a single-chip solution for embedded networking and telecom designs. A PowerQUICC processor is a specialized microprocessor that combines a PowerPC CPU core with dedicated communications peripherals on a single die. It sits in the embedded MPU hierarchy as: microprocessor -> 32-bit embedded processor -> communications controller. PowerQUICC parts are widely deployed in legacy telecom, industrial control, and networking equipment where deterministic communications processing is required. Key features include a 66 MHz core clock, 4 KB instruction cache and 4 KB data cache, dual UART, dual SCC (Serial Communication Controller) channels for HDLC/PPP/ATM, I2C and SPI interfaces, a 10/100 Ethernet MAC, and on-chip DRAM controller. The integrated CPM offloads protocol processing from the CPU, freeing the core for application-level tasks. Architecturally, the MPC860 uses a Harvard-style cache, separate instruction and data buses, and a dedicated peripheral bus for the CPM. The 66 MHz 'SR' speed grade is one tier below the 80 MHz 'VR' grade but offers equivalent peripheral set, providing a cost-optimized option for designs that do not require maximum throughput. Typical applications include industrial routers, ISDN terminal adapters, set-top box controllers, factory automation bridges, and legacy telecom line cards. The wide operating temperature range (0 to 95 C) and integrated peripherals simplify board design and reduce BOM cost for these embedded systems. When designing with this part, note that the 357-ball BGA requires careful PCB layout with via-in-pad recommended for thermal dissipation. Designers should also verify errata documents from NXP, as the MPC860 family has several documented silicon revisions (D4557 masks). Use the Freescale/NXP development toolchain (CodeWarrior) for firmware development. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers sourcing legacy PowerQUICC parts evaluate the MPC860SRZQ66D4557 against modern alternatives.

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.

The NXP MPC862PVR100B is a 32-bit PowerQUICC microprocessor from the MPC8xx family, integrating a PowerPC core with a Communications Processor Module (CPM) on a single die. It operates at 100 MHz, runs from a 3.3 V supply, and is housed in a 357-pin PBGA package measuring 25 mm x 25 mm. The device is fabricated on a 0.32 um CMOS process and is offered in tray packaging for industrial production lines. A PowerQUICC microprocessor is a system-on-chip that combines a high-performance PowerPC integer unit with a RISC-based communications processor module. The architecture is designed for embedded networking and telecom applications where deterministic I/O handling, multi-protocol serial support, and ATM/HDLC processing must coexist with a general-purpose control plane. MPC8xx family members occupy a position in the broader Power Architecture hierarchy: PowerPC embedded CPU -> PowerQUICC family -> MPC8xx generation -> communications processor class. Key features of the MPC862PVR100B include 100 MHz core frequency, on-chip CPM with support for Fast Ethernet, HDLC, UART, I2C, IrDA, and SPI peripherals, dual 10/100 Ethernet MACs, and a 32-bit address/data bus.

The integrated CPM offloads protocol processing from the core, allowing the PowerPC CPU to run application code while dedicated RISC engines handle DMA channels, serial protocols, and packet routing. This dual-engine approach is what historically distinguished the MPC8xx family from simpler single-core microcontrollers and made it popular in routers, DSLAMs, and industrial control equipment throughout the 2000s. Typical applications include SOHO routers, integrated access devices, ISDN terminal adapters, industrial serial gateways, and legacy telecom infrastructure where ATM, HDLC, and multi-channel UART handling are required. The wide peripheral integration reduces external chip count and PCB area. When designing with this part, ensure proper thermal management because the 357-pin PBGA package concentrates dissipation in a relatively small die. Decouple each power pin with 0.1 uF ceramic capacitors and use a 4-layer PCB with continuous power and ground planes. The 3.3 V supply must remain within the 3.135 V to 3.465 V window under all transient conditions. This page synthesizes distributor pricing, drop-in same-package alternatives, and design notes derived from the MPC862/857T/857DSL family datasheet that are not compiled on any single distributor listing.

MPC862PVR66B - PowerQUICC MPC862 MPU 66MHz 357-PBGA | NXP

The NXP MPC862PVR66B is a PowerQUICC communications processor from the MPC8xx family, integrating a 32-bit PowerPC core running at 66 MHz with on-chip communications peripherals in a 357-ball PBGA (25x25 mm) package. It is a 1-core, 32-bit RISC microprocessor built on a 0.32 micrometer CMOS process, designed for embedded networking and telecom equipment that require deterministic communications performance. A PowerQUICC processor is a PowerPC-based microprocessor family that combines a PowerPC core with integrated communications engine modules (CPM), serial interfaces, and memory controllers, targeting routers, switches, and remote-access equipment. Within the broader taxonomy it sits as: PowerPC -> 32-bit embedded MPU -> PowerQUICC -> communications processor -> integrated circuit. The MPC8xx line historically served as the workhorse MPU for telecom-grade WAN interfaces (T1/E1, Ethernet, HDLC) before the architecture transitioned to PowerQUICC II/III and QorIQ families. Key features of the MPC862PVR66B include a 66 MHz core frequency, an integrated CPM (Communications Processor Module), dual 10/100 Mbps Ethernet MACs, multi-channel HDLC, and a 32-bit data path. The 357-PBGA package provides a robust ball-grid-array footprint with dedicated power/ground balls to support industrial thermal envelopes. The "PVR66B" suffix encodes the package (PBGA), the 66 MHz speed grade, and a NXP/Freescale designator; the lead-free "B" suffix indicates lead-free (Pb-free) termination. Typical applications include branch-office routers, DSLAM line cards, industrial serial concentrators, and protocol-conversion gateways where deterministic HDLC and Ethernet MAC integration simplify BOM. When laying out the 357-PBGA footprint, follow NXP's recommended 1.27 mm pitch ball pattern with matched-length impedance-controlled Ethernet and TDM traces; provide at least four dedicated ground balls stitched to an internal ground plane to maintain signal integrity at full Ethernet throughput.
