Belonging to the MPC859DSL family, this 1-core MPU combines the PowerPC core with peripheral subsystems optimized for ATM, HDLC, and Ethernet communications. A PowerQUICC microprocessor is a system-on-chip (SoC) communications controller that integrates a PowerPC processor core with specialized peripheral engines (the CPM - Communications Processor Module) designed to offload networking tasks from the main CPU. The MPC8xx series sits in the hierarchy: PowerQUICC -> Power Architecture microprocessor -> embedded MPU -> integrated circuit. These parts historically target Customer Premises Equipment (CPE) and enterprise telecom designs where deterministic communications handling and integrated peripheral support reduce component count. Key features of the MPC859PCVR100A include a 100 MHz PowerPC core, integrated CPM with support for multiple ATM SAR priority levels, two 10/100 Mbps Ethernet MACs, HDLC/PPP support, and parallel I/O. The 357-PBGA 25x25 mm package provides high-density interconnect for the wide internal bus structures. Compared with the MPC860, the MPC859DSL adds enhanced SAR (ESAR) features such as multiple APC priority levels and port-to-port switching without host intervention. Typical applications include DSLAM line cards, integrated access devices, multichannel routers, VoIP gateways, and ATM edge concentrators. The part is well suited to designs that previously used the MPC860SAR and need additional SAR functionality without changing the toolchain. When designing with this device, designers must allocate adequate PCB real estate for the 25x25 mm PBGA and plan thermal dissipation paths. Long-term procurement planning is essential because the MPC859 has been classified by NXP/Freescale as a mature/legacy product line.

It integrates a 32-bit PowerPC core with the MPC8xx family peripheral set, including a communications processor module (CPM), system interface unit, memory controller, and PCMCIA interface, making it a versatile system-on-chip for telecom and embedded networking applications. What is a PowerQUICC microprocessor? A PowerQUICC (pronounced 'power-quick') device is a family of integrated communications processors originally developed by Motorola (later Freescale, now NXP) that combines a PowerPC CPU core with on-chip peripheral controllers optimized for networking, telecommunications, and embedded control. The PowerQUICC sits in the broader hierarchy of microprocessor -> embedded processor -> communications processor -> integrated system-on-chip. The MPC859 family targets routers, bridges, WAN access, and industrial control designs where deterministic communication and on-chip peripheral integration reduce bill-of-materials cost. Key features include a single 32-bit core running at 100 MHz, a hardware multiply/accumulate unit, dedicated CPM with multiple serial channels, four 16-bit timers, system integration unit with bus sizing, an 8/16/32-bit ROM/FLASH/SRAM/DRAM controller, a PCMCIA interface supporting two card slots, and a 32-bit PC-AT ISA-style local bus. Industrial temperature screening of -40C to +100C supports telecom outdoor and industrial enclosure deployments. Architecturally, the MPC859DSL integrates the CPU core, CPM, and SIU on a single die, providing deterministic real-time response by offloading DMA, serial protocol handling, and bus arbitration to dedicated hardware. This eliminates the software overhead typical of general-purpose CPUs performing protocol stacks, enabling sustained serial throughput even under heavy interrupt load. The 357-PBGA package exposes the full local bus, CPM I/O, and PCMCIA signals needed for design reuse across the MPC8xx family. Typical applications include enterprise router control planes, ISDN/T1/E1 channel banks, industrial serial concentrators, multi-port serial controller cards, and PCMCIA-based storage peripherals. The 100 MHz core and CPM architecture deliver wire-speed serial handling for telecom access multiplexers while remaining a single-chip solution. When designing with the MPC859TCVR100A, ensure the 357-pin PBGA land pattern is routed with matched-length control for the 60x bus plus all 32-bit data signals. Provide bulk decoupling near each BGA quadrant to suppress core and I/O switching noise; consider a four-layer minimum stack-up with dedicated power planes for GVDD and VDDQ rails. This page synthesizes distributor pricing, drop-in alternatives from the PowerQUICC family, and practical design notes not found in the standalone manufacturer datasheet, providing a single reference for engineers specifying the MPC859TCVR100A in new designs or maintenance programs.

It integrates a 32-bit RISC CPU core, a separate 32-bit RISC communications-processor module (CPM), system integration functions, memory controllers, and a versatile peripheral set on a single die. A PowerQUICC microprocessor is a system-on-chip (SoC) optimized for embedded telecommunications and networking equipment, where the host CPU runs control-plane software and the CPM offloads serial-channel and protocol processing. The MPC8xx series belongs to the broader Power Architecture microcontroller family, descending from the original PowerPC embedded line, and bridges the gap between simple MCUs and high-end PowerPC processors for routers, switches, and industrial controllers. Key features include a 100 MHz 32-bit core with 0.18 µm CMOS process, 3.3 V I/O supply, integrated CPM supporting multiple serial channels (typically SCCs, FCCs, and an SPI/I2C), a 32-bit data bus, and on-chip dual-port RAM for descriptor and buffer management. According to the NXP hardware-specifications document, the part is qualified for commercial-grade 0 °C to 95 °C operation and supports JTAG boundary-scan for production test. Architecturally, the MPC859TVR100A places dedicated DMA engines inside the CPM so that Ethernet, HDLC, UART, and other serial traffic never interrupt the host core. This offload model keeps the host CPU available for routing-table management, SNMP, or real-time control loops, which is the central reason PowerQUICC devices dominated WAN edge and telecom equipment through the late 1990s and 2000s. Typical applications include WAN access routers, ISDN terminal adapters, xDSL modems, industrial serial-protocol gateways, and embedded telecommunications controllers where deterministic serial-channel throughput outweighs the need for a GHz-class application processor. The 357-BGA package supports high-pin-count parallel buses and multiple PHY interfaces on a single board. Designers should plan for the device's discontinued long-term supply status by validating last-time-buy dates with authorized distributors and stocking production quantities before EOL windows close. PCB layout must follow the BGA escape rules for the 25 mm x 25 mm substrate and ensure proper thermal vias under the package to keep junction temperature within the 0-95 °C operating range.

The integrated system interface unit provides DRAM, SRDRAM, and ROM/Flash control. The architecture pairs the PowerPC-style CPU with the CPM co-processor so that low-level protocol work (Ethernet, HDLC, UART, transparent bit streams) runs independently, leaving the core free for control-plane or routing software. The 133 MHz speed grade supports throughput-demanding serial links while keeping power dissipation within industrial-thermal envelopes. Typical applications include industrial routers and gateways, telecom control cards, networked process controllers, ISDN/T1/E1 access equipment, and legacy SCADA nodes. Because the part is marked End-of-Life by NXP, it is mostly used in maintenance, repair, and long-life-cycle industrial deployments where re-design is not feasible. When designing with the MPC859TVR133A, ensure the supply voltages (core 1.8V, I/O 3.3V) are well-decoupled and that boot configuration pins are pulled to the correct levels; mis-configuration is the most common MPC8xx field failure. Use a JTAG-controlled debugger for first-stage bring-up since the masked internal ROM expects specific memory-map layout at reset.

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.

The NXP MPC860DTVR50D4 is a 32-bit PowerQUICC communications microprocessor from the MPC8xx family, featuring a single PowerPC core running at 50 MHz, integrated in a 357-ball PBGA package (25 x 25 mm). It is targeted at embedded communications and networking controller applications where deterministic performance, on-chip peripheral integration, and low system cost matter more than raw CPU throughput. The device combines a PowerPC integer core with the CPM (Communications Processor Module), which offloads serial communications tasks such as HDLC, Ethernet, UART, and SCC/SMC channels from the main CPU. A microprocessor (MPU) is an integrated circuit that contains the central processing unit, instruction decoding, register files, and cache/memory management logic for a complete computing engine, typically integrated with peripherals onto a single die. 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.

The device combines a 32-bit RISC CPU core, the CPM for HDLC/ATM/10 Mbps Ethernet, PCMCIA interface logic, DRAM controller, and on-chip peripherals in a single system-on-chip. A PowerQUICC microprocessor belongs to the MPU (microprocessor unit) class of integrated circuits, historically positioned as a communications-centric system-on-chip that merges a PowerPC processor core with dedicated serial-protocol engines. In the system hierarchy, it sits above general-purpose microcontrollers, offering higher deterministic I/O bandwidth for telecom and networking equipment where offloading protocol framing from the CPU is essential. Key features include the integrated CPM with RISC communication engines, dual 10 Mbps Ethernet MACs, ATM and HDLC support, PCMCIA controller, DRAM controller with bus sizing logic, and the standard PowerPC memory management unit. The 66 MHz core clock drives both the CPU and the CPM, while the external bus supports 32-bit data paths at up to 66 MHz. The 3.3 V supply rail and 0 to 95 C operating temperature make it suitable for industrial embedded systems. Typical applications include telecom switching fabric, ISDN terminal adapters, ATM/Frame Relay access devices, industrial routers, and legacy networking equipment. The combination of CPU + CPM is especially valuable where deterministic serial-channel handling must coexist with higher-layer protocol stacks without external ASICs. When designing with this device, note that the 357-PBGA package requires multi-layer PCB design with controlled-impedance routing for the external bus; verified JTAG and BDM debug tools must be used for development. The part is Not For New Designs per distributor listings, so consider migration to MPC860SAR or newer PowerQUICC II/III variants for new projects.

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

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

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.

MPC860ENZQ50D4R2518

MPC860ENZQ50D4R2518 - 50MHz PowerQUICC MPU, 357-PBGA | NXP

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

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.
