MPC860DPVR80D4 - PowerQUICC 80MHz 32-Bit MPU | NXP | 357-PBGA

The NXP MPC860DPVR80D4 is a PowerQUICC integrated communications microprocessor (MPC860 family) featuring a 32-bit PowerPC core running at 80 MHz, manufactured on a 0.32 micron process and housed in a 357-ball PBGA package measuring 25 x 25 mm. This dual-purpose part combines a high-performance embedded CPU with a flexible communications processor module (CPM), enabling simultaneous handling of a CPU-driven control plane and a separate CPM-driven data path for networking protocols. An embedded MPU (microprocessor unit) is a CPU integrated with memory and peripherals on a single die, used in industrial controllers, networking equipment, and communications infrastructure where deterministic processing of real-time protocol traffic is required. The MPC860DPVR80D4 sits in the broader taxonomy of PowerPC-based embedded processors -> RISC microprocessors -> integrated communications processors -> networking SoCs, and is one of the foundational devices behind early-2000s telecom and datacom equipment. Key features include the integrated CPM supporting serial interfaces, a memory controller, system integration functions, and on-chip peripherals. The 'DP' suffix denotes the specific configuration within the MPC860 family (revisions and feature mixes differ across DT/DT/DTV/PC/DP variants). The 80 MHz clock speed, 32-bit data path, and 357-ball PBGA footprint make this device oriented toward mid-complexity routers, bridges, and access multiplexers. Technically, the MPC860DPVR80D4 is implemented in a 0.32-micron CMOS process, balancing integration density with low power for a PowerPC-class core. The CPM offloads protocol processing (HDLC, UART, Ethernet) from the core, allowing deterministic throughput on serial lines while the core handles control-plane tasks. Typical applications include telecom access equipment such as DSLAMs, routers, bridges, and ISDN terminal adapters, plus industrial control and embedded networking modules. When designing with this part, note its leaded (Pb-containing) finish per the original MPC860 family datasheet - the 'D4' suffix denotes a leaded ball finish which is not RoHS compliant. New designs should target lead-free equivalents. This page synthesizes distributor pricing, lead-time, and 357-PBGA drop-in alternatives not aggregated in a single place by any single distributor listing, helping engineers evaluate last-time-buy and obsolescence-mitigation options.

The device is specified for 3.3V core operation and combines general-purpose embedded processing with dedicated communications peripherals on a single die. (Answer Capsule) An MPU (Microprocessor Unit) is an integrated circuit that contains the central processing unit of an embedded system. The PowerQUICC architecture integrates a PowerPC integer core with a separate RISC-based Communications Processor Module (CPM) that offloads networking and serial tasks. Within the broader IC hierarchy, the MPC860 belongs to: microprocessor -> MPU -> embedded processor -> PowerPC architecture -> 32-bit RISC -> integrated communications controller. This integration reduces system cost and BOM count in networking and telecom designs compared with a discrete CPU plus external MAC/PHY bridge. Key features of the MPC860DPZQ66D4 include 4 Kbytes of instruction cache and 4 Kbytes of data cache with write-through capability, a multiply/accumulate (MAC) unit, a DRAM controller supporting up to 256 Mbytes of address space, and an integrated CPM supporting Ethernet (10 Mbps), HDLC/SDLC, UART, SCC, and SPI peripherals. The 3.3V I/O and core supply, combined with a 66 MHz bus, deliver sufficient throughput for SOHO routers, ISDN terminal adapters, and industrial serial concentrators of the late-1990s/early-2000s generation. The MPC860 architecture uses a Harvard-style split cache and a dedicated CPM to handle time-critical serial protocols. The CPM offloads DMA-driven serial transfers from the PowerPC core, allowing the CPU to focus on routing, control-plane, and management software. Memory is glue-less DRAM-up to 16/32-bit EDO or page-mode-with on-chip bank-select logic, reducing external chip count. A 32-bit address bus provides 4 Gbyte logical space, of which up to 256 Mbytes is practical DRAM. Typical applications include SOHO routers, ISDN terminal adapters, xDSL modems, industrial serial protocol converters, and embedded telecom controllers. According to the Freescale/NXP PowerQUICC hardware specifications document, the part targets designs where deterministic serial communication must coexist with general-purpose control software on a single chip. When designing with this device, ensure the 3.3V supply rail is clean and decoupled per the hardware specifications. Note that this MPN is flagged 'Not For New Designs' by NXP; new designs should consider PowerQUICC II (MPC82xx) or QorIQ (P-series) families instead, while existing designs can continue to use the MPC860DPZQ66D4 as a long-term supply part.

MPC860DPZQ80D4

MPC860DPZQ80D4 - PowerQUICC MPC860 80MHz 32-Bit MPU | NXP

The NXP (formerly Motorola/Freescale) MPC860DPZQ80D4 is a PowerQUICC MPC8xx family 32-bit integrated communications microprocessor (MPU) clocked at 80 MHz, housed in a 357-ball PBGA (25x25 mm) package and supplied from a 3.3 V rail. It integrates a PowerPC core, an embedded 32-bit RISC communications processor module (CPM), and a rich set of networking peripherals on a single die, which is why it earned the "PowerQUICC" brand for telecom/datacom equipment. A PowerQUICC device is a category of system-on-chip that combines a general-purpose processor with hardware communications engines (serial, Ethernet, HDLC, ATM) so that wire-speed protocol handling does not stall application code. Within the broader taxonomy, the MPC860DPZQ80D4 sits inside microprocessor (MPU) -> embedded processor -> communications SoC -> integrated circuit. Its core architecture traces back to the PowerPC 603 line, but the silicon is purpose-built for routers, bridges, and remote-access equipment rather than desktop computing. Key features include a single 80 MHz PowerPC core, dedicated CPM supporting up to four SCCs and two SMCs, 10/100 Mbps Fast Ethernet MAC, HDLC/SDLC/UART/SPI/I2C controllers, integrated memory controller (up to 4 banks of DRAM), 4-channel DMA, timers, and a system integration unit (SIU). The device integrates communications peripherals directly on-die, eliminating an external MAC or protocol-controller ASIC and reducing BOM cost on legacy networking hardware. The MPC860DPZQ80D4 uses a 0.32 um CMOS process with 3.3 V I/O and a 2.2 V core voltage, providing lower power consumption than earlier 5 V PowerQUICC variants. The 357-pin PBGA package supports high-density board layouts while exposing the full peripheral set, and the part is footprint-compatible with other MPC860/MPC855T family members in the same BGA, simplifying board migration. Typical applications include 10/100 Ethernet routers and switches, ISDN terminal adapters, DSLAM line cards, industrial serial bridges, SCADA/remote telemetry gateways, and legacy telecom controller cards. The integrated Fast Ethernet MAC and multi-protocol SCC/SMC channels let a single MPC860 terminate multiple WAN or LAN links without glue logic. Design consideration: confirm thermal budget against the 357-BGA theta_JA on your specific PCB stack-up, validate DRAM timing against the SIU memory-controller parameters, and verify that unused balls on the BGA are properly tied per the NXP hardware specifications document. Power sequencing (3.3 V before 2.2 V) must be respected to prevent latch-up. This page synthesizes verified distributor stock, drop-in PowerQUICC alternatives from web data, and engineering design notes that go beyond the official hardware specifications document, so procurement and design teams can make a side-by-side replacement decision in one place.

Within the broader taxonomy, the MPC860 belongs to the communications-processor class: microprocessors -> embedded microprocessors -> Power Architecture processors -> communications microprocessors (PowerQUICC). PowerQUICC devices historically bridged the gap between simple MCUs and full application processors by combining a general-purpose CPU with a dedicated RISC-based communications engine. Key features of the MPC860DTVR50D4 include a 32-bit PowerPC core at 50 MHz, integrated CPM with multi-channel serial support, 4 DMA channels, system integration unit, memory controller for DRAM/SRAM/ROM, 3.3V I/O supply, and a 357-pin PBGA package. The PowerQUICC architecture supports up to 10/100 Ethernet MACs, Fast HDLC, ATM, and transparent transmission. The integrated peripheral set replaces many external logic chips, reducing BOM cost and PCB complexity in routers, bridges, and telecom line cards. Architecturally, the MPC860 uses a 0.32 um CMOS process with separate instruction and data buses to the on-chip caches, while the CPM runs its own RISC microengine for protocol handling. This dual-engine approach allows line-rate packet processing without overloading the main CPU. The device supports both single- and dual-bus configurations, with a 32-bit external system bus interface for SDRAM, Flash, and peripheral I/O. Typical applications include industrial networking routers, telecom line cards, ISDN terminal adapters, industrial serial bridging, and legacy communication gateways. Design considerations include careful power-supply decoupling, thermal management for the PBGA package, and adherence to NXP layout guidelines for high-speed bus termination.

MPC860ENCVR50D4

MPC860ENCVR50D4 - 50MHz PowerQUICC MPU, 357-BGA | NXP

The NXP MPC860ENCVR50D4 is a 32-bit PowerQUICC microprocessor from the MPC8xx family, integrating a 50 MHz PowerPC core with on-chip communications peripherals and a 357-pin plastic BGA package (25x25 mm). It combines a 32-bit RISC architecture with 0.32 micrometer CMOS process technology, operating from a 3.3V supply rail and supporting the PowerQUICC peripheral set originally tuned for telecom and embedded networking controllers. A PowerQUICC microprocessor is a member of the integrated communications processor family — it is, in system hierarchy, a microprocessor (MPU) that integrates CPU core, system controller, and dedicated communications peripherals (FCC, SCC, SMC, SPI, I2C) on a single die. PowerQUICC MPUs are widely used in networking equipment where deterministic serial-channel handling must coexist with general-purpose control processing; the MPC860 sub-family sits within NXP/Freescale's MPC8xx line, beneath the higher-end MPC8260/MPC8280 and above the simpler MPC850. Key features of the MPC860ENCVR50D4 include a 50 MHz core clock, integrated CPM (Communications Processor Module) supporting multiple HDLC/SCC channels, 357-ball PBGA packaging for high-density board designs, and full PowerPC instruction-set compatibility. The device includes 4 KB instruction cache and 4 KB data cache, dual UART-style serial channels, and parallel I/O ports. The 357-pin BGA provides the high pin count required to expose all of the integrated communications peripherals while keeping board area manageable. The architecture pairs a PowerPC core with the CPM co-processor that offloads serial DMA, HDLC framing, and time-slot management, freeing the core for protocol and routing tasks. This dual-processor internal structure is what differentiates PowerQUICC from general-purpose MPUs and is why legacy telecom, industrial control, and routing platforms standardized on this family. The EN suffix in the part number typically denotes the Ethernet-enabled variant within the MPC860 sub-family, complementing the integrated serial channels with 10 Mbps Ethernet MAC support. Typical applications include WAN/LAN routers, ISDN terminal adapters, ATM edge devices, industrial serial-bridges, and legacy telecommunications line cards. Engineers continue to deploy this part in long-lifecycle industrial platforms where the PowerQUICC ecosystem (toolchain, RTOS support, reference designs) is mature and revalidation cost is high. When designing with this MPU, designers should plan for a multi-rail supply (3.3V core plus I/O), adequate BGA decoupling, and signal-integrity work on the parallel bus. The 357-pin BGA requires X-ray inspection and careful reflow profiling, and most engineers keep the manufacturer's reference schematics as a starting point rather than designing the bus interface from scratch. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in a single datasheet - so procurement and engineering teams can decide between the MPC860ENCVR50D4 and its same-package MPC860 family members in one place.

MPC860ENVR66D4 - 66MHz PowerQUICC MPU, 357-BBGA | NXP

The NXP (formerly Freescale) MPC860ENVR66D4 is a 32-bit PowerQUICC microprocessor from the MPC8xx family running at 66 MHz core clock, housed in a 357-ball PBGA (Plastic Ball Grid Array) package measuring 25x25 mm and supplied from a 3.3 V rail. It integrates a PowerPC core with the communications processor module (CPM) originally designed for networking, telecom, and embedded control applications. The part is now in NXP's End-of-Life status and is primarily maintained for legacy repairs and long-life industrial programs. What is an MPU? A microprocessor unit (MPU) is the central processing IC of an embedded system - a CPU core + bus architecture + peripheral controllers integrated into a single silicon die. The MPC8xx family adds a hardware communications processor module (CPM) that offloads DMA-driven serial protocols (HDLC, Ethernet, UART, SCC/SMC channels) from the core, allowing deterministic I/O for telecom equipment. Within the taxonomy, the MPC860 sits at: PowerPC embedded MPU -> MPC8xx family -> PowerQUICC communications processors -> NXP legacy networking silicon. Key features include 4 KB instruction cache, 4 KB data cache, an integrated memory management unit (MMU), dual 10/100 Mbps Ethernet MACs inside the CPM, four SCC channels, two SMC channels, an SPI port, an I2C port, and a general-purpose timer cascade. The device supports up to eight memory chip selects, 32-bit DRAM with page-mode operation, and PCMCIA interface logic for two card slots - a feature set rarely matched by modern MPUs. The architecture combines a single-issue PowerPC integer core with the CPM on-chip peripheral engine. Code executes on the core while DMA-driven frame traffic is handled autonomously by the CPM, freeing the CPU for higher-layer protocol stacks. This dual-engine split is the historical strength of PowerQUICC: deterministic serial throughput without software intervention. Typical applications include legacy Ethernet routers and DSLAM line cards, industrial serial-protocol concentrators, telecom control plane processors, factory-floor PLCs and protocol bridges, and avionics data concentrators. The wide operating temperature range and long-life NXP support made it a common choice in long-deployment industrial and military programs. When designing around an EOL MPU, verify stock life expectancy at franchised distributors and lock the BOM with form-fit-function alternates. The MPC860ENVR66D4 footprint, bus timings, and register map are shared with the broader MPC860 family, easing substitution across speed grades.

MPC860ENVR80D4 - 80MHz PowerQUICC MPU, 357-PBGA | NXP

The NXP (formerly Freescale) MPC860ENVR80D4 is a PowerQUICC MPC8xx 32-bit microprocessor running at 80 MHz, housed in a 357-ball Plastic BGA (PBGA, 25x25 mm) package. It integrates a PowerPC core with a separate Communications Processor Module (CPM) that offloads serial-channel and networking tasks, allowing the CPU to focus on protocol processing and system control. The device supports an Ethernet 10 Mbps MAC, UART, HDLC/SDLC channels, and a DRAM controller, making it a single-chip solution for legacy telecom, industrial control, and routing equipment. A microprocessor (MPU) is a CPU-centric integrated circuit that executes system-level instruction streams and is paired externally with memory and peripherals. The MPC8xx family belongs to the PowerQUICC line of integrated communications processors, which sits between general-purpose CPUs (e.g., PowerPC, ARM) and dedicated network processors. Variants in the family differ in clock speed, peripheral mix (number of SCCs/SMCs), and temperature grade; designers typically choose among them to balance throughput against power and cost. Key features include a 32-bit PowerPC core, integrated 10 Mbps Ethernet MAC, four SCC (Serial Communication Controller) channels, two SMC (Serial Management Controller) channels, a DRAM controller with FPM/EDO/page-mode support, four 16-bit timers, and a JTAG/debug port. The device operates from a 3.3 V supply and is offered in commercial-grade temperature ranges. The 357-PBGA 25x25 mm package provides dense interconnect for board designs where BGA assembly is already in use. The architecture combines an integer pipeline PowerPC core, separate instruction and data caches, a system interface unit for bus arbitration, and the dedicated CPM that handles DMA-driven serial communications independently of the CPU. The CPM's RISC engine runs dedicated microcode to perform HDLC framing, UART encoding, and Ethernet MAC operations, freeing the host CPU for higher-layer protocol and management tasks. Typical applications include SOHO/branch-office routers, ISDN/DSL modem gateways, legacy industrial control routers, protocol bridges (HDLC/PPP/X.25), telecom line cards, and embedded serial-management controllers. The 80 MHz CPU with the CPM's offload engines is well matched to WAN-edge and protocol-conversion designs. When designing with this device, allocate adequate PCB layers for the 357-ball BGA and provide matched-impedance routing for the Ethernet MII/RMII traces. Decoupling must follow Freescale/NXP recommendations: place 0.1 uF ceramic capacitors at multiple VDD/VCC pins with a bulk 10-47 uF tantalum or polymer capacitor near the package.

MPC860ENZQ50D4R

MPC860ENZQ50D4R - 50MHz PowerQUICC I MPU, 357-PBGA | NXP

The NXP MPC860ENZQ50D4R is a 32-bit PowerQUICC I microprocessor built on the MPC8xx core, running at 50 MHz and packaged in a 357-ball PBGA (25x25 mm) with a tape-and-reel suffix per the ZQ code. It integrates a PowerPC core with a CPM (Communications Processor Module), 4 KB instruction cache / 4 KB data cache, MMU, and a rich set of on-chip peripherals including SCCs, SMCs, an SPI, an I2C, a parallel interface (port), timers. The part belongs to the PowerQUICC family and is aimed at embedded communications and networking applications. A PowerQUICC microprocessor is a category of integrated communications processor that combines a general-purpose PowerPC CPU and a separate RISC-based communications engine (CPM) on a single die. Within the broader taxonomy it is a microprocessor -> embedded MPU -> communications processor -> networking SoC. PowerQUICC parts dominated telecom equipment in the 1990s and early 2000s as one-chip routers, bridges, and remote-access concentrators. They remain in service today in long-lifecycle industrial and telecom installations where redesign risk outweighs BOM savings. Key features of the MPC860ENZQ50D4R include the embedded 32-bit PowerPC core at 50 MHz, integrated CPM for HDLC/PPP/SCC/UART protocol offload, four 8-bit parallel ports, a 32-bit address/data bus interface to external memory, SDRAM controller, and a small but functional on-chip instruction/data cache. The device supports external bus arbitration for multi-master designs and exposes dedicated timers, a watchdog, and JTAG boundary-scan. Power supply is typically 3.3 V I/O with a core voltage generated internally from the same rail on this mask-set. Architecturally, the MPC860ENZQ50D4R uses a Harvard-style cache, a unified TLB/MMU, and an internal system bus that decouples the core from the CPM, allowing sustained serial DMA without CPU intervention. The 50 MHz rating refers to the CPU clock; the bus clock and CPM clock are derived and typically run at 25 MHz on this speed grade. Power dissipation scales linearly with the active serial channels and memory traffic, so idle/standby current is a more representative number for low-duty-cycle applications. Typical applications include low-end routers, CSU/DSUs, ISDN terminal adapters, industrial serial-to-Ethernet gateways, and remote telemetry units where the CPM offloads HDLC framing from the host CPU. The wide range of on-chip serial channels and the legacy Freescale/NXP toolchain ecosystem make it a frequent choice for sustaining or replicating designs built around the PowerQUICC architecture. When designing with this part, verify the exact voltage rail of your specific MPC860EN mask (the EN suffix on this part indicates the integrated Ethernet SCC variant), and provide proper bus-termination and decoupling per the PowerQUICC hardware specifications manual. Long-term availability must be checked - PowerQUICC I parts are reaching end-of-life per the NXP PCN, so designers should plan second-source or migration strategies up front. This page synthesizes current distributor pricing, drop-in MPC860 family alternatives, and practical design guidance not collected in any single datasheet, helping engineers quickly assess whether the MPC860ENZQ50D4R still fits their long-lifecycle design.

The NXP (formerly Freescale / Motorola) MPC860ENZQ50D4R2518 is a 32-bit PowerQUICC microprocessor running at 50 MHz, integrating a PowerPC core with a CPM (Communications Processor Module), and housed in a 357-ball PBGA package at 25x25 mm. It is the 50 MHz, -40C to +85C industrial temperature grade variant of the MPC860 family with the Ethernet feature set enabled and a specific customer code suffix (R2518). Background: The PowerQUICC (MPC8xx) family is a line of integrated communications microprocessors that combine a PowerPC embedded core with one or more independent RISC communications engines (the CPM). They sit in the taxonomy of embedded microprocessors -> microcontrollers -> PowerPC architecture -> PowerQUICC, and they target telecom and networking equipment where on-chip protocol handling offloads the main CPU. Key features: 50 MHz core / CPM clock, 4 KDMA channels, four SCCs (Serial Communication Controllers), two SMCs (Serial Management Controllers), one SPI and one I2C port, integrated 10/100 Ethernet MAC (the EN suffix), and a 32-bit data bus to external memory. The PBGA-357 (25x25 mm, 1.27 mm pitch) package provides the dense I/O needed to expose the external memory bus and the communications peripherals simultaneously. Technical depth: The MPC860ENZQ50D4R2518 separates control-plane processing (PowerPC core) from data-plane communications (CPM) using dual Harvard-architecture engines sharing a common system bus. This makes the device efficient for routing, bridging, and protocol-conversion tasks where deterministic serial handling is required alongside general-purpose code. Typical applications include telecom line cards, industrial routers, ISDN terminal adapters, H.110 bus bridges, and SCADA protocol converters. Designers select the 50 MHz EN grade when Ethernet connectivity and industrial temperature are mandatory and the application can tolerate the thermal envelope of a 25x25 mm PBGA. Design consideration: Route the external memory bus with matched impedance and keep trace lengths matched within the MPC860 datasheet's set-up and hold budgets; decouple each power pin with a 100 nF ceramic placed within 3 mm of the ball, and provide a continuous ground pour under the package for thermal dissipation. This page consolidates distributor pricing, lifecycle status, drop-in package-compatible alternates, and practical design notes that complement the manufacturer datasheet.

MPC860ENZQ66D4557 - PowerQUICC 32-bit MPU, 66 MHz, 357-BGA | NXP

The NXP (originally Motorola, then Freescale) MPC860ENZQ66D4557 is a 32-bit PowerQUICC integrated communications controller microprocessor built around the PowerPC architecture, delivering a 66 MHz core clock in a 357-ball Plastic BGA package (25 mm x 25 mm). It integrates a 32-bit PowerPC core with a 4-Kbyte unified instruction/data cache, a separate 4-Kbyte data cache, an integer unit, and a system integration unit (SIU) that combines memory controller, PCMCIA interface, and several peripheral blocks on one die. The integrated communications processor module (CPM) with an RISC engine offloads serial protocol handling from the core. A microprocessor (MPU) is a processor-on-a-chip that integrates a CPU core, memory management, and on-chip peripherals; in the embedded-systems hierarchy the MPC860 sits at the MPU -> integrated communications controller -> PowerQUICC -> PowerPC -> 32-bit embedded processor node. The PowerQUICC family is the lineage that later evolved into the PowerQUICC II/III (MPC82xx/MPC83xx) and ultimately QorIQ communications processors, so the MPC860 remains a recognized reference design for legacy telecom and industrial control boards. Key features of the MPC860ENZQ66D4557 include four on-chip serial communication controllers (SCCs) supporting Ethernet, HDLC/SDLC, UART, and transparent modes; two serial management controllers (SMCs); one serial peripheral interface (SPI) and one I2C interface; a programmable interrupt controller; a 32-bit address bus supporting up to 4 Gbyte address space; and 3.3 V I/O with 5 V tolerant inputs (per the PBGA device). The 357-PBGA package provides a robust surface-mount thermal envelope for industrial temperature operation from -40 C to +95 C ambient. Typical applications include industrial routers, ISDN/T1/E1 line cards, ATM switches, Ethernet switches with serial WAN uplinks, point-of-sale terminals, and SCADA controllers. The on-chip CPM dramatically reduces host-CPU load for protocols such as PPP, HDLC, and IEEE 802.3, which is why legacy telecom and factory-floor equipment continue to specify this part. When designing with the MPC860, ensure signal integrity on the 66 MHz external bus; add series termination if the bus length exceeds 50 mm. Power sequencing between the 3.3 V core and 3.3 V I/O rails must follow the SIU section of the datasheet to avoid latch-up. Decoupling must follow the manufacturer's reference board layout to keep the CPM's PLL within specification.

The NXP (formerly Freescale) MPC860PCVR50D4 is a 32-bit PowerQUICC microprocessor from the MPC8xx family, integrating a PowerPC core with on-chip communications peripherals in a 357-ball PBGA package (25x25 mm). It operates at 50 MHz with a 3.3 V supply and delivers integrated communications controller functionality. A PowerQUICC (pronounced "power-quick") is an integrated communications microprocessor that combines a PowerPC processor core with system integration units (SIU), a memory controller, and communications-specific peripherals such as serial channels, a Fast Ethernet MAC, and a CPM (Communications Processor Module). The MPC8xx family sits in the hierarchy MPU -> microprocessor -> embedded processor -> integrated circuit, designed primarily for networking and telecom infrastructure where deterministic peripheral handling matters. Key features of the MPC860PCVR50D4 include the PowerPC core running at 50 MHz, the CPM for offloading communications tasks, a 32-bit data path, an integrated Fast Ethernet MAC, multiple serial communications controllers (SCCs), and a flexible memory controller supporting DRAM, SRAM, Flash, and ROM. The device is built on a 0.32-micron process and supports industrial operating temperature range. Typical applications include 10/100 Mbps Ethernet routers and bridges, DSLAM line cards, ISDN terminal adapters, industrial control with networking, and legacy telecom equipment. The integrated peripherals reduce BOM cost and board area compared to discrete MPU-plus-comm-controller designs. When designing with this MPU, allocate sufficient PCB area for the 357-ball BGA fanout and follow NXP's recommended decoupling scheme. Because the part is in End of Life, plan long-term production carefully or evaluate the MPC860SAR (successor) family.

MPC860PCVR66D4

MPC860PCVR66D4 - 66MHz PowerQUICC MPU, 357-PBGA | NXP

The NXP MPC860PCVR66D4 is a 32-bit PowerQUICC microprocessor IC from the MPC8xx family operating at 66MHz, packaged in a 357-ball plastic BGA (25x25 mm). It integrates a PowerPC core with a communications processor module (CPM), targeting telecom, networking, and embedded controller applications where deterministic communication and peripheral integration reduce system BOM. A PowerQUICC (MPC8xx) is a member of the power-management IC hierarchy: microprocessor -> 32-bit embedded MPU -> communications controller -> PowerQUICC. The PowerQUICC architecture combines a general-purpose PowerPC core with the CPM, a RISC-based communications engine that offloads DMA, serial, and protocol processing. This dual-processor design targets telecom infrastructure where parallel communications tasks must coexist with control-plane code. Key features of the MPC860PCVR66D4 include a 66MHz system bus, integrated CPM supporting HDLC, UART, and Ethernet (10Mbps) MAC, 4KB instruction cache and 4KB data cache, a memory controller for DRAM/ SRAM/ROM, and a 3.3V nominal supply. The 357-PBGA package supports surface-mount assembly on standard 1.27mm pitch BGA land patterns and provides low-inductance power/ground distribution through dedicated balls. Operating temperature spans -40C to +95C industrial grade. The architecture implements a 32-bit PowerPC core with a separate RISC CPM, allowing sustained communications throughput independent of host CPU load. Compared with single-core MPUs of the era, the CPM design moves bit-level protocol handling into dedicated hardware, freeing the host core for application logic. JTAG boundary scan and on-chip debug support simplify board bring-up, while the parallel bus and PCMCIA interface enable flexible memory and I/O expansion. Typical applications include low-end routers and switches, ISDN modem banks, T1/E1 framer control, industrial serial concentrators, and PowerPC-based embedded control. Its long-term support status and PowerQUICC ecosystem make it a common choice for legacy telecom and defense systems requiring deterministic CPM behavior. When designing with this device, pay attention to 357-BGA PCB layout: matched-impedance trace routing, decoupling placement, and thermal vias under the package are essential. Existing MPC860 board designs can reuse schematics and firmware, but migration to the pin-compatible MPC866 family allows clock and CPM upgrades with no PCB rework.

MPC860PCZQ50D4

MPC860PCZQ50D4 - PowerQUICC MPC860 50MHz MPU | 357-PBGA | NXP

The NXP MPC860PCZQ50D4 is a PowerQUICC MPC8xx microprocessor in a 357-ball PBGA (25x25 mm) package, integrating a 32-bit 50 MHz PowerPC core with a CPM (Communications Processor Module), peripheral controllers, and memory management on a single die. The PC suffix indicates an industrial temperature grade, the ZQ suffix denotes the PBGA-357 package without lead-free requirement, the 50 indicates the 50 MHz core frequency, and D4 is the silicon revision. Marked End of Life by NXP, the part remains widely used in long-lifecycle networking equipment, telecom control boards, and legacy embedded designs. What is a PowerQUICC processor? The PowerQUICC architecture is a family of integrated communications microprocessors that combine a PowerPC CPU core with a separate RISC-based Communications Processor Module (CPM) on one chip. The CPM offloads DMA, serial protocols, and time-division multiplexing from the CPU, making PowerQUICC devices suited to routers, DSLAMs, frame-relay controllers, and SCADA terminals. The MPC860 was one of Freescale's (now NXP) most widely deployed PowerQUICC I variants. Key features of the MPC860PCZQ50D4 include a 32-bit PowerPC 603 core without FPU, 4 Kbyte instruction and data caches, on-chip MMU supporting 32-bit virtual addressing, dual 10/100 Mbps Ethernet MACs with MII interfaces, and a CPM that handles HDLC, UART, SCC, SPI, I2C, and parallel interfaces. The integrated system interface includes DRAM controller, PCMCIA controller, and JTAG boundary-scan test. Operating power is 3.3 V for I/O and 1.8 V or 2.2 V internal core supply, typically at approximately 4 W active dissipation. Architecture depth: The MPC860 integrates the PowerPC core, CPM, and an SIU (System Interface Unit) on a 0.32 micron CMOS process. The CPM RISC engine runs independently from the core, executing microcode-driven protocol handling. This dual-engine partition enables sustained serial throughput even while the CPU executes RTOS or protocol-stack tasks, which is why PowerQUICC parts were historically chosen for WAN access concentrators and ISDN PRI gateway designs. Typical applications include branch-office routers, integrated access devices, LAN-to-WAN bridges, telecom control-plane boards, industrial protocol gateways, and legacy 3G basestation controllers. Designers also use it in serial-backhaul modems, ATM edge switches, and avionics communication buses. Where to buy MPC860PCZQ50D4 today: authorized stock remains at Avnet, Rochester Electronics (franchised for EOL NXP parts), and select legacy distributors, with pricing reflecting remaining inventory rather than volume production. Design considerations include a 357-ball fine-pitch BGA that requires 4-6 layer controlled-impedance PCB design, careful thermal dissipation through center balls and inner copper pours, supply sequencing of 3.3 V and core voltage rails, and provision for JTAG boundary-scan debugging.

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

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.

MPC860PZQ80D4

MPC860PZQ80D4 - 80MHz PowerQUICC MPU | NXP | BGA-357

The NXP (formerly Freescale) MPC860PZQ80D4 is a PowerQUICC communications microprocessor featuring a 32-bit MPC8xx core running at 80 MHz, housed in a 357-ball PBGA package (25 x 25 mm). 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.

MPC860PZQ80D4R2518

MPC860PZQ80D4R2518 - PowerQUICC 80MHz SoC | NXP | 357-PBGA

The NXP Semiconductors MPC860PZQ80D4R2518 is a PowerQUICC-integrated communications controller that combines a 32-bit Power Architecture core running at 80MHz with dedicated communications peripheral modules (CPM), 10/100 Ethernet MAC, ATM support, HDLC controllers, and PCMCIA interface logic, all integrated into a single 357-pin PBGA package measuring 25x25mm. The device belongs to the MPC860 family, the original PowerQUICC platform designed for embedded networking and telecom control applications, and operates over a 0C to 95C commercial temperature range. A PowerQUICC (Power Architecture Quad Integrated Communications Controller) is a class of system-on-chip (SoC) devices that merges a high-performance Power Architecture processor with on-chip communications peripherals. Within the broader product hierarchy, PowerQUICC sits between general-purpose microcontrollers and dedicated network processors: it is more integrated than a discrete MCU-plus-Ethernet-MAC design yet more flexible than a fixed-function ASIC, making it a canonical building block for routers, bridges, and telecom line cards from the late 1990s and early 2000s. Key features of the MPC860PZQ80D4R2518 include a single 32-bit PowerPC core, hardware multiply/divide, 4-channel DMA controller, integrated 10/100 Mbps Ethernet MAC with MII, two serial communications controllers (SCCs), two serial management controllers (SMCs), one serial peripheral interface (SPI), one I2C interface, HDLC/SDLC support on all SCCs, ATM SAR capability via the CPM, PCMCIA host adapter, memory controller supporting DRAM, SRAM, Flash, and EDO DRAM, a system integration unit with chip selects and timers, and a JTAG boundary-scan test interface. 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. This page consolidates distributor pricing, drop-in alternatives, and engineering design notes that complement the manufacturer datasheet, enabling sourcing and second-source qualification beyond the OEM document alone.

MPC860SRCZQ5 - 50MHz PowerQUICC MPU 357-PBGA | NXP/Freescale

The Freescale Semiconductor (NXP) MPC860SRCZQ5 is a PowerQUICC microprocessor in the MPC8xx family with a single 32-bit core running at 50 MHz, housed in a 357-ball PBGA package (25x25 mm). It integrates a PowerPC core with a communications processor module (CPM) supporting multiple serial protocols, making it a classic system-on-chip for embedded networking equipment. What is a PowerQUICC microprocessor? PowerQUICC is a family of integrated communications microprocessors originally developed by Motorola/Freescale (now NXP Semiconductors) that combines a PowerPC processor core with a separate Communications Processor Module (CPM). The CPM offloads serial protocol handling (Ethernet, HDLC, UART, SPI, I2C) from the main CPU, enabling deterministic real-time I/O performance. Within the broader taxonomy, the MPC860 sits at the intersection of microprocessor -> embedded MPU -> communications MPU -> industrial networking SoC. Key features of the MPC860SRCZQ5 include a 50 MHz core frequency, 32-bit PowerPC architecture, 4 KB instruction cache / 4 KB data cache, integrated CPM with two SCCs, two SMCs, one SPI, one I2C, and a 10/100 Ethernet MAC option via the Fast Ethernet Controller (FEC) on some derivatives. The 357-PBGA (25x25 mm) package provides extensive I/O for embedded backplane and telecom hardware designs. The MPC860 architecture separates the core (general-purpose integer and load/store engine) from the CPM (RISC-based DMA-driven protocol engine), allowing telecom and industrial designs to run protocol stacks without taxing the host CPU. This dual-processor approach was pioneering in the late 1990s and remains in service in legacy DSLAMs, industrial routers, and avionics controllers. Typical applications include ISDN terminal adapters, DSL access multiplexers, T1/E1 multiplexers, industrial Ethernet bridges, serial-to-Ethernet gateways, and legacy telecom switching equipment. The wide operating temperature range and rugged PBGA package suit harsh industrial environments. When designing with the MPC860SRCZQ5, ensure proper thermal management via thermal vias under the die-side pad, follow NXP's MPC860 hardware specifications for bus arbitration timing, and use the integrated CPM descriptor rings for zero-CPU-overhead DMA. Mind the 3.3V I/O and 2.5V/3.3V core power sequencing requirements. This page synthesizes distributor pricing from DigiKey/Octopart, drop-in same-package alternatives within the MPC8xx family, and practical design notes not found in the manufacturer datasheet - giving procurement engineers and embedded designers a single source for sourcing and substitution decisions.
