MPC8572VTAVNE557 - PowerQUICC III 1.5GHz Dual-Core MPU | NXP

The NXP (formerly Freescale) MPC8572VTAVNE557 is a PowerQUICC III integrated communications processor featuring two Power Architecture e500 cores running at 1.5 GHz in a 1023-ball FCBGA (33x33) package. The device integrates 32-Kbyte L1 instruction and data caches per core with parity protection, plus a shared L2 cache, and is built on a 32-bit Book E-enhanced Power Architecture technology. The part number suffix 'VTAVNE' denotes a 1.5 GHz core frequency, -40C to +105C industrial temperature range, and the 1023-FCBGA package; '557' is a specific die revision/ordering code. A PowerQUICC III is a high-performance communications microprocessor that combines general-purpose processing cores with integrated networking and peripheral accelerators, primarily targeting wired and wireless infrastructure, telecom switching, and industrial control. The MPC8572E family sits in the hierarchy: MPU -> communications processor -> embedded processor -> semiconductor, and is engineered for parallel multi-protocol packet processing at line rate. Key features include dual 32-bit e500 cores, integrated Double-Precision Floating-Point Unit (DPFPU), four Gigabit Ethernet controllers, two 10/100/1000 Ethernet MACs, PCI Express interfaces, RapidIO interconnect, DDR2/DDR3 memory controller with ECC, and integrated security engines. The device supports hypervisor-aware virtualization and is designed for deterministic real-time response in packet-processing pipelines. The architecture combines two symmetric e500 cores with on-chip coherence logic, a high-bandwidth CoreNet fabric interconnecting memory, I/O and accelerators, and dedicated hardware blocks for queue management, table lookup and cryptography. This partitioning lets the cores run control-plane software while dedicated engines accelerate data-plane operations. Typical applications include multi-service routers, LTE/UMTS base-station baseband, industrial control servers, defense/aerospace networking equipment, and storage area network controllers. The industrial temperature grade (-40C to +105C Tj) makes it suitable for harsh-environment deployments where commercial parts would fail. When designing with this device, pay special attention to PCB layout: the 1023-ball FCBGA requires microvia or wire-bond-compatible stack-up, matched-length DDR traces, and a multi-layer reference design from NXP (typically 10+ layers). Power sequencing of the 1.0V core, 1.5V/1.8V DDR and 3.3V I/O rails must follow the datasheet sequence to prevent latch-up.

MPC857DSLCVR66B

MPC857DSLCVR66B - 66MHz PowerQUICC MPU 357-BGA | NXP

The NXP MPC857DSLCVR66B is a PowerQUICC MPC8xx microprocessor IC featuring a single 32-bit core running at 66MHz, fabricated on a 0.32-micron process, and housed in a 357-pin Plastic BGA (PBGA) package measuring 25x25 mm. The device belongs to NXP's MPC857 PowerQUICC family, integrating a PowerPC core with on-chip peripherals including communication controllers for networking and embedded telecom infrastructure. The 66.66MHz core frequency gives it a 1.2V-2.0V core and 3.3V I/O typical supply architecture in a single-chip control solution. What is an MPU (Microprocessor Unit)? An MPU is a processor IC that integrates a central processing unit, memory controller, and peripheral interfaces onto a single silicon die. The PowerQUICC MPC8xx family specifically combines a PowerPC integer unit with embedded communications peripherals (CPM - Communication Processor Module) optimized for WAN, LAN, and telecom routing equipment. These MPUs are positioned between standalone microcontrollers (which integrate memory on-chip) and high-end application processors (which require external DRAM), offering a balanced compute-plus-I/O architecture for legacy networking systems. Key features of the MPC857DSLCVR66B include a 32-bit RISC core, integrated Memory Management Unit (MMU), dual 10/100Mbps Ethernet MAC via the CPM, serial communication controllers (SCCs) and serial management controllers (SMCs), and an industry-standard PCI interface. The 357-ball PBGA package provides 1.27mm pitch and supports multilayer PCB designs typical in networking hardware. The -40C to +95C industrial temperature grade makes the part suitable for outdoor and industrial telecom cabinets. Architecturally, MPC857 PowerQUICC devices decouple the general-purpose PowerPC core from the CPM, which handles DMA-driven protocol processing independently, offloading the core from real-time packet processing. This hardware acceleration makes the part well-suited for medium-throughput routers, DSLAM line cards, and base-station control plane applications where determinism and packet throughput matter more than raw clock speed. Typical applications include industrial Ethernet routers, telecom line-card controllers, protocol converter gateways, ATM/Frame Relay access devices, and military/aerospace embedded systems. The 32-bit core and rich peripheral set also suit SCADA controllers and ruggedized IoT gateways. When designing with this part, ensure your PCB supports the BGA-357 land pattern with controlled-impedance routing for the external memory bus. Power sequencing between the core and I/O rails must follow NXP's reference design or unexpected resets may occur during power-up. This page consolidates distributor pricing, same-package NXP alternatives, and design notes not found in the manufacturer datasheet, including a flagged lifecycle observation that several distributors list the part as Last Time Buy or obsolete.

MPC857DSLVR50B - MPC8xx PowerQUICC MPU 50MHz 357-PBGA | NXP
MPC857DSLVR50B

MPC857DSLVR50B - MPC8xx PowerQUICC MPU 50MHz 357-PBGA | NXP

The NXP MPC857DSLVR50B is a PowerQUICC MPC8xx microprocessor IC integrating one PowerPC 32-bit core running at 50 MHz with the CPM (Communications Processor Module) co-processor, packaged in a 357-ball PBGA at 25x25 mm. According to the manufacturer product page, the device belongs to the MPC8xx family and is targeted at PowerQUICC communications-processor applications. The 'DSLVR50B' suffix decodes as: DSL = PBGA-357 / Leaded / 0 to 105C operating temperature grade, VR = 50 MHz core, B = revision B silicon. An MPU (Microprocessor Unit) is the central processing unit of an embedded system, executing instruction streams fetched from memory and orchestrating peripherals. The MPC8xx family is a line of PowerPC-based microprocessors in the broader taxonomy MPU -> embedded processor -> microprocessor -> integrated circuit -> semiconductor. The 'PowerQUICC' name denotes NXP/Freescale parts that pair a PowerPC core with the CPM (Communications Processor Module) - a RISC engine dedicated to serial-communication tasks, offloading DMA, HDLC, Ethernet, ATM, and serial-protocol handling from the main CPU. Key features of the MPC857DSLVR50B include 50 MHz PowerPC core, integrated CPM with up to 10 Mbps Ethernet (one port) plus 10/100 Mbps Ethernet (one port), DRAM controller, and a 32-bit external data bus. The 357-ball plastic BGA exposes the full PowerQUICC peripheral set: SCCs, SMCs, SPI, I2C, PCMCIA, memory controller, and general-purpose I/O. Per the NXP product listing, the part is built on a 0.32 micrometer process and ships in tray packaging. Architecturally, the device combines an integer PowerPC core with the CPM coprocessor via an internal bus; the CPM uses microcode-driven RISC engines (CPs) for serial channel termination, enabling simultaneous multi-protocol handling. The 32-bit core performs general control-plane code (RTOS, networking stack, system management), while the CPM handles time-critical data-plane communication without CPU intervention. The integrated DRAM controller and PCI bridge (via UTOPIA/standard MPC8xx peripherals) reduce the chip count of typical routing/bridging designs. Typical applications include industrial Ethernet routers, telecom edge equipment, protocol bridges, low-speed DSL/cable modem control planes, and embedded control-plane subsystems requiring deterministic serial-channel handling. The 50 MHz core and CPM combination is well suited to designs where the host CPU runs management/control software while the CPM terminates serial bearers in parallel. When designing with this part, verify that the 357-ball PBGA PCB land pattern, power-rail sequencing, and 50 MHz system clock match the MPC8xx reference design. Pay particular attention to the BSDL/ boundary-scan compliance and the JTAG TAP for production test. Because this part is reported as obsolete by some distributors, lifecycle planning and second-source identification are recommended during the design phase. This page synthesizes distributor pricing, the same-family NXP alternatives, and practical design considerations that are not consolidated in the manufacturer datasheet.

MPC857DSLZQ50B

MPC857DSLZQ50B - PowerQUICC MPC8xx MPU 50MHz 357-PBGA | NXP

The NXP MPC857DSLZQ50B is a PowerQUICC communications processor built on 32-bit Power Architecture, integrating a single MPC8xx core running at 50 MHz with the CPM (Communications Processor Module) for protocol offload. Housed in a 357-ball PBGA package (25x25 mm), it targets embedded networking equipment that requires deterministic serial-channel handling with low system cost. The part is specified over the 0 to 105 C commercial operating range and is supplied in tray packaging. A PowerQUICC processor is a category of integrated communications microprocessor that combines a PowerPC embedded core with dedicated serial-protocol engines (SCCs, SMCs, SPI, I2C, UART) and a 10/100 Ethernet MAC, eliminating the need for an external protocol-handling CPU. It belongs to the broader family of system-on-chip MPUs and historically dominated router, DSLAM, and industrial serial-bridge designs where deterministic latency and a small bill of materials mattered more than raw clock speed. Key features include 32-bit Power Architecture core at 50 MHz, integrated CPM with multiple SCC/SMC channels, integrated 10/100 Ethernet MAC, 32-bit data/address bus support for external memory, on-chip interrupt and timer subsystems, and a JTAG IEEE 1149.1 test access port. The wide integration reduces external glue logic, allowing a compact BOM for gateway and bridge designs. Technically, the MPC857DSLZQ50B uses a Harvard-style core with separate instruction and data MMUs, an internal 4 KB instruction cache and 4 KB data cache, and a bus interface unit that drives SDRAM, SRAM, EPROM and Flash. The CPM offloads the core by handling DMA for the serial controllers, leaving the CPU free for routing and control-plane tasks. Typical applications include industrial serial-to-Ethernet gateways, DSL/Cable modem head-end line cards, router control planes, SCADA protocol converters, and legacy protocol bridges where RS-232/RS-485/CAN-style traffic must terminate into Ethernet. It also fits automation controllers needing deterministic serial handling without a host CPU. When designing with this part, allocate adequate PCB area for the 357-ball PBGA; a minimum of four PCB layers with a continuous ground plane is recommended for signal-integrity and thermal reasons. Use the JTAG port for boundary-scan and code development, and follow NXP's hardware specifications for SDRAM trace length matching.

MPC857TCZQ66B

MPC857TCZQ66B - PowerQUICC MPU, 32-Bit 66MHz 357-PBGA | NXP

The NXP MPC857TCZQ66B is a PowerQUICC microprocessor from the MPC8xx family featuring a 32-bit single core running at 66 MHz, housed in a 357-pin PBGA (Plastic Ball Grid Array) package measuring 25 mm x 25 mm. Originally designed by Freescale Semiconductor (now part of NXP), this PowerQUICC part integrates a PowerPC core with communication peripherals for embedded networking and telecommunications systems. A PowerQUICC (PowerPC QUICC) MPU is a category of integrated communications processor that combines a PowerPC execution core with on-chip peripheral subsystems optimized for networking, telecom, and data transport applications. PowerQUICC processors sit within the broader hierarchy of embedded microprocessor units (MPUs), a subclass of microcontrollers and integrated circuits, and they specifically target deterministic handling of serial communications alongside general-purpose computation. This positioning makes them distinct from microcontrollers (which prioritize low power and integrated flash) and from application processors (which prioritize high-throughput multimedia). Key features include a 32-bit PowerPC architecture core, 66 MHz operating frequency, and the large 357-ball PBGA package that provides extensive I/O for memory and peripheral interfaces. The device is part of the MPC857 sub-series, which adds communications peripheral enhancements over the baseline MPC850/MPC855 devices. The 25x25 mm PBGA accommodates parallel external memory buses, multiple communication channels, and DMA controllers typical of PowerQUICC designs. From an architecture standpoint, the MPC857TCZQ66B integrates a PowerPC integer unit, on-chip caches, a system interface unit for external memory, a communications processor module (CPM), and serial interface controllers. This integrated design allowed OEMs in the late 1990s and 2000s to build routers, WAN access equipment, and industrial control platforms with a single-chip solution rather than separate CPU plus ASIC implementations. Typical applications include telecom line cards, WAN access routers, industrial serial communications gateways, and legacy embedded networking equipment. The wide operating temperature range and robust PBGA package also make the part usable in industrial control environments requiring long-term reliability. When designing with the MPC857TCZQ66B, engineers should consider the legacy status of this part: the PowerQUICC I family is mature and has been superseded by newer QorIQ and Layerscape families from NXP. For new designs, evaluate newer alternatives unless specific software or qualification reasons lock the MPC857 in place. Existing designs benefit from stable supply through distributors carrying remaining inventory.

MPC857TVR66B

MPC857TVR66B - PowerQUICC MPC8xx 32-Bit 66MHz MPU | NXP

The NXP (formerly Freescale) MPC857TVR66B is a PowerQUICC MPC8xx 32-bit microprocessor running at 66 MHz, housed in a 357-ball PBGA package measuring 25 mm x 25 mm. It is a single-core PowerQUICC device from the MPC860/MPC857T/MPC857DSL family that integrates a PowerPC core with communications peripherals, aimed at networking and embedded telecom equipment. The part is supplied from a 3.3 V rail and is offered in tray packaging with RoHS-compliant lead-free terminations. A microprocessor (MPU) is an integrated circuit that fetches, decodes, and executes instructions from program memory using an internal CPU core. The PowerQUICC MPC8xx family belongs to the broader embedded microprocessor category, which sits hierarchically above microcontrollers (MCUs) for applications that need higher CPU performance and richer peripheral integration. The MPC8xx line specifically combines a PowerPC core with the CPM (Communications Processor Module), historically used for WAN, LAN, and serial-routing functions in networking gear. Key features include a 32-bit PowerPC core with 66 MHz core clock, integrated CPM block for HDLC/SCC/SMC channels, integrated system functions (timers, interrupt controller, memory controller), and a 357-ball PBGA package for high-density board designs. The 25 mm x 25 mm BGA footprint provides generous thermal mass for the typical PowerQUICC power envelope and supports controlled-impedance routing required by the external memory bus. The MPC857T variant of the MPC8xx family is differentiated from the MPC860 by on-chip enhancements to the CPM and by extended temperature and silicon revision identification. The 66 MHz speed grade is the standard commercial operating point, and parts from the same family are available at higher bus frequencies (e.g., MPC857TVR80B). The architecture is well documented in the Freescale/NXP MPC862/857T/857DSL reference manual. Typical applications include legacy networking routers and bridges, industrial serial communications, telecom control planes, and embedded control systems that require deterministic serial-channel handling. Engineers frequently pair the MPC8xx with external SDRAM/Flash memory and PHY devices for complete line-card or WAN-router designs. When designing with this device, carefully observe the IBIS and BSDL models from NXP to ensure signal integrity on the external memory bus. Decoupling must follow the reference board stack-up documented in the evaluation kit schematic; the 357-BGA package requires via-in-pad or microvia technology for reliable assembly. Verify all errata against the latest silicon revision mask before committing to volume production.

MPC857TZQ100B

MPC857TZQ100B - 100MHz MPC8xx PowerQUICC MPU BGA-357 | NXP

The NXP Semiconductors MPC857TZQ100B is a PowerQUICC MPC8xx microprocessor IC integrating one 32-bit core running at 100MHz, fabricated on a 0.32 micrometer CMOS process and housed in a 357-pin plastic BGA package measuring 25x25 mm. Originally designed by Freescale Semiconductor and now sourced from NXP USA Inc. via Rochester Electronics as a long-term support distributor, this part targets embedded telecom and networking systems where deterministic PowerPC performance and integrated communications peripherals are required. A microprocessor (MPU) is an integrated processing device that fetches, decodes, and executes instructions from external memory, sitting one level above microcontrollers in the embedded-compute hierarchy. Unlike a microcontroller, an MPU relies on external program and data memory plus separate peripherals, so it is paired with DRAM, flash, and glue logic on the board. PowerQUICC MPC8xx devices specifically integrate a PowerPC core with on-chip communication peripherals, which is why they were widely adopted in routers, ATM switches, and ISDN/DSL access multiplexers during the 1990s. Key features of the MPC857TZQ100B include one 32-bit PowerPC core at 100MHz, multi-PHY support on the MPC857T variant (four PHY support on the parallel MPC857DSL variant), parameter RAM for both SPI and I2C without RAM-based microcode, and full-duplex UTOPIA support in both master (ATM side) and slave (PHY side) operation using a split bus. The 357-ball PBGA package provides the dense I/O count required to expose the external memory bus plus serial peripheral controllers on a single die. Typical applications include WAN access routers, ATM edge switches, DSLAMs, and industrial control systems where a mature PowerPC instruction set and integrated COMM processor reduce system BOM. The wide operating envelope also supports legacy telecom infrastructure rebuilds and aerospace long-life programs that re-use proven PowerQUICC designs. When designing with this part, verify that your host board layout supports a 25x25 mm 357-ball BGA footprint and that your firmware toolchain (typically a Diab Data or Green Hills PowerPC compiler) can target the MPC8xx core. Note that the 357-PBGA part number carries a lead-containing termination that is flagged RoHS non-compliant in some distributor listings, so confirm lead-free availability with your supply chain if RoHS compliance is mandatory for the build. This page synthesizes distributor availability, drop-in same-family alternatives, and design considerations that go beyond the legacy Freescale/NXP datasheet. Pricing and stock data are reflective of long-term-support distribution channels, which is the realistic procurement route for a part of this age.

It runs at a 50 MHz core clock, manufactured on a 0.32 micrometer CMOS process, and is supplied in tray packaging. The device combines a CPU, system integration functions, and a communications processor module for embedded networking and telecom designs. A microprocessor (MPU) is an integrated circuit that contains the arithmetic logic unit, control unit, and register set of a computer on a single chip. Unlike a microcontroller (MCU), which typically includes flash memory and analog peripherals, an MPU relies on external memory and is optimized for high-throughput data-plane workloads. Within the broader taxonomy, the MPC857TZQ50B sits as: MPU -> microprocessor -> processor -> semiconductor. The PowerQUICC family historically dominated router, switch, and wireline telecom hardware because it merged a PowerPC core with dedicated communication-engine blocks. Key features of the MPC857TZQ50B include a single 32-bit core at 50 MHz, the classic MPC8xx system integration unit with memory controllers, DMA, timers, and serial interfaces, and a CPM (Communications Processor Module) for HDLC/PPP/SCPCI traffic offload. The 357-ball PBGA package provides high I/O density for the parallel system bus, memory interface, and communications ports. The device supports industrial-grade operating conditions typical for the PowerQUICC generation. The architecture combines a PowerPC integer core with a RISC-style communications processor, allowing protocol handling without burdening the host CPU. The 0.32 um CMOS process balances transistor density with the ruggedness required for long-life telecom and industrial programs. This dual-engine approach is what made the PowerQUICC line the de-facto choice for legacy WAN routers, PBX systems, and basestation control. Typical applications include WAN routers and access multiplexers, ISDN/DSL line cards, industrial serial protocol gateways, and legacy telecom control boards. Long-lifecycle programs in railway signaling, defense communications, and avionics databuses continue to design around this platform because of its proven reliability and the existing firmware ecosystem. When designing with the MPC857TZQ50B, ensure PCB layout follows BGA fan-out best practices with microvia or via-in-pad escape routing, and provide bulk bypass capacitance near the 3.3 V and 1.8 V supply rails. The 357-ball BGA has no leaded alternative footprint, so any second-source decision must match the same package and pin map to avoid board rework.

Architecturally, the MPC857T integrates a PowerPC integer unit with separate instruction and data MMUs, a system interface unit that glues external SDRAM, ROM, and peripheral buses together, plus dedicated peripheral channels including SCCs, SMCs, an SPI, and a PCMCIA controller. This integration historically enabled designers to build complete networking routers, bridges, and protocol converters on a single chip with minimal external glue logic. Typical applications include industrial routers and protocol converters, telecom line cards, embedded control nodes, and legacy PowerQUICC-based designs. Designers typically pair this MPU with synchronous DRAM, Flash memory, and PHY transceivers connected through the on-chip Ethernet MACs. When designing with this part, ensure the 3.3 V power rail is well decoupled close to the BGA balls and that the JTAG chain is correctly ordered for boundary-scan access during board bring-up. Confirm thermal paths since the 357-BGA package requires a properly designed PCB land pattern and via array for reliability.

The NXP MPC859DSLCVR50A is a 32-bit PowerQUICC microprocessor from the MPC8xx family, integrating a PowerPC core with on-chip communications peripherals and running at 50 MHz, housed in a 357-ball PBGA (25x25 mm) package. It features a 1.8V core voltage, 3.3V I/O voltage, a 32-bit RISC-style PowerPC architecture, and 0.18 µm CMOS process technology. A PowerQUICC (PowerPC Quad Integrated Communications Controller) microprocessor is a specialized embedded processor that combines a PowerPC CPU core with dedicated peripherals for networking and telecommunications. Within the broader hierarchy, MPC8xx parts are embedded microprocessors (a subcategory of microcontrollers / MPU ICs) that target serial-communication-intensive designs such as routers, WAN interfaces, and industrial control. The 50 MHz core frequency, integrated SCCs (serial communication controllers), and PCI bridge make the MPC859DSLCVR50A a classic building block for legacy telecom and embedded networking equipment. Key features include 50 MHz core clock speed, 32-bit PowerPC core, integrated communications processor module (CPM) with multiple serial interfaces, integrated memory controller supporting DRAM/EDO, a 32-bit PCI interface, and low-power 1.8V core operation. The 357-ball PBGA package is a plastic ball grid array measuring 25x25 mm, designed for surface-mount assembly on high-density embedded boards. Technically, the MPC859DSLCVR50A uses the PowerPC 603e-derived core with a unified 4 KB instruction and 4 KB data cache, hardware MMU, and dual-port RAM between the core and the CPM. The CPM offloads communications tasks from the CPU through independent RISC engines, enabling wire-speed serial handling while the core runs application code. The 0.18 µm CMOS process delivers low power dissipation and high integration density. Typical applications include WAN routers and CSU/DSU equipment, industrial serial networking hubs, ISDN terminal adapters, embedded communications controllers, protocol converters, and legacy telecom infrastructure requiring deterministic serial performance. When designing with this device, note that it requires external SDRAM/DRAM, boot ROM, and a system PLL reference. Designers should consult the MPC866/859 hardware specifications document for AC/DC electrical characteristics and pin multiplexing. The 357-ball BGA requires X-ray inspection and reflow profiling compatible with large-array packages.

MPC859DSLVR50A

MPC859DSLVR50A - PowerQUICC MPU 50MHz 357-PBGA | NXP

The NXP MPC859DSLVR50A is a PowerQUICC integrated communications controller from the MPC8xx family that combines a 32-bit Power Architecture microprocessor core with a Communications Processor Module (CPM) on a single die. Operating at 50 MHz, it integrates one 32-bit core, a CPM supporting 10 Mbps Ethernet and optional 10/100 Mbps Ethernet, and DRAM control in a 357-ball PBGA package at 25x25 mm. This specific MPC859DSLVR50A variant is targeted at DSL modem, Integrated Access Device (IAD), and residential gateway Customer Premises Equipment (CPE) applications. An integrated communications controller (PowerQUICC) is a category of system-on-chip that merges a general-purpose microprocessor core with dedicated communications peripherals and memory controllers. PowerQUICC belongs to the broader family of microprocessors, which sit above microcontrollers and below full applications processors in the embedded processing hierarchy. Compared to a discrete CPU-plus-communications-ASIC design, a PowerQUICC reduces component count, board area, and BOM cost while preserving deterministic CPM-driven serial handling for telecom workloads. Key features include a 50 MHz core, 66 MIPS peak throughput, on-chip DRAM controller, two serial interfaces for ATM/HDLC, USB, I2C, and SPI peripherals, an enhanced SAR (ESAR) mode that adds multiple ATM priority levels and port-to-port switching versus the legacy MPC860SAR, and industrial-grade 0 to 95 C operation. The device is built on a 0.18 micron CMOS process and supports 3.3 V I/O with a separate core voltage rail. The architecture splits work between the core (general control-plane and management tasks) and the CPM (real-time channelized serial, ATM AAL, and HDLC processing). This dual-engine design lets DSLAM-facing software run on the core while the CPM handles per-channel SAR, framing, and DMA autonomously, which keeps overall CPU utilization low at high channel counts. Typical applications include DSL modems, Integrated Access Devices, residential gateways, low-port ATM SAR edge devices, and industrial serial routing controllers. The integrated CPM offloads per-channel SAR processing so the Power Architecture core stays free for routing, firewalling, and management-plane software. When designing with the MPC859DSLVR50A, ensure the 3.3 V and core rails are sequenced correctly and that the 357-ball PBGA land pattern is laid out for adequate thermal dissipation; sustained CPM activity can push junction temperatures high in enclosed CPE enclosures. The MPC859 family is in NXP's End-of-Life product list, so plan last-time-buy volumes carefully for long-lifecycle programs.

An MPU (Microprocessor Unit) is the central processing block of an embedded computing system, sitting above the memory and peripheral subsystem in the hardware hierarchy. Within NXP's PowerQUICC family, the MPC8xx series combines a scalar PowerPC core with a dedicated RISC communications processor, allowing networking and telecom tasks (HDLC, ATM, Ethernet) to be offloaded from the main core. The MPC859 specifically adds an integrated 10/100 Mbps Fast Ethernet MAC and supports up to four serial communications controllers. Key features include a 66 MHz core frequency, 87 MIPS Dhrystone throughput, integrated 10/100 Ethernet, four SCCs (Serial Communication Controllers), two SMCs (Serial Management Controllers), USB support, I2C, SPI, and a DRAM controller supporting SDRAM, EDO, and FPM modes. The 357-PBGA package provides extensive I/O for telecom and industrial applications. The 'SL' suffix denotes the extended temperature grade of 0°C to +95°C, suited for commercial and light-industrial environments. Typical applications include telecommunications equipment such as DSLAM line cards, ISDN routers, and VoIP gateways, as well as industrial control systems, factory automation, and embedded networking appliances. The combination of a fast PowerPC core and a separate CPM makes the part well suited for systems that must handle real-time protocol processing concurrently with control-plane software. When designing with this MPU, ensure the 3.3 V supply rail is well decoupled and that the RESET configuration is pulled correctly during boot. Engineers should budget for external SDRAM and Flash, since the part has no on-chip non-volatile memory. Pin compatibility across the MPC866/859/860 family allows drop-in upgrades to higher-speed variants without PCB rework.

MPC859DSLZP50A - PowerQUICC 50MHz Comm Processor | NXP | BGA-357

The NXP (formerly Freescale) MPC859DSLZP50A is a PowerQUICC integrated communications processor featuring a 32-bit Power Architecture core running at 50 MHz, housed in a 357-pin PBGA package measuring 25 mm x 25 mm. It is a member of the MPC866/859 family of versatile single-chip integrated microprocessors and peripherals designed for customer-premises equipment (CPE) communications. Background Knowledge: A PowerQUICC (Power Architecture QUICC) integrated communications processor is a system-on-chip that combines a high-performance Power Architecture CPU core with dedicated communications peripheral engines such as serial communication controllers, ATM controllers, and fast Ethernet MACs. It sits in the hierarchy of communications ICs > network processors > embedded processors > microprocessors, and historically bridged the gap between general-purpose MCUs and dedicated network ASICs for telecom/datacom infrastructure. Key features of the MPC859DSLZP50A include a single 32-bit Power Architecture core at 50 MHz, dual 10/100 Mbps Ethernet MACs, multiple serial communication controllers (SCCs), an ATM Utopia interface, and a peripheral bus supporting up to 32 address bits. The device operates from a 1.8 V core supply and 3.3 V I/O supply. It is specifically tailored for DSL modems, integrated access devices (IADs), and residential gateways, where its CPM (Communications Processor Module) offloads protocol processing from the CPU. The MPC859DSL uses a 0.18-micron CMOS process with low-power modes including doze, sleep, and deep-sleep, allowing idle power reduction in always-on CPE equipment. The CPM can independently handle SCC, SMC, SPI, I2C, and USB protocol layers, enabling wire-speed WAN-side framing without CPU intervention. Typical applications include DSL modems, integrated access devices (IADs), residential gateways, SOHO routers, and industrial serial-protocol bridges. Its combination of Ethernet MACs, ATM support, and multi-protocol SCCs makes it especially well-suited for converged voice/data CPE where multiple T1/E1, UART, or HDLC links must be aggregated onto an Ethernet uplink. Design consideration: Because this part is end-of-life on NXP's product page, designers evaluating it for new designs should plan for last-time-buy and consider NXP's QorIQ or PowerQUICC II/III successors for greenfield projects, while the MPC859DSL remains a viable pin-compatible upgrade for legacy repair and existing designs. This page synthesizes distributor stock signals, NXP's end-of-life notices, and practical design notes on the MPC866/859 PowerQUICC family that are not consolidated in a single manufacturer document.

MPC859TCVR100A - 100MHz PowerQUICC MPU, 357-PBGA | NXP

The NXP MPC859TCVR100A is a 32-bit PowerQUICC integrated communications processor built on Power Architecture, operating at 100 MHz core frequency and housed in a 357-pin plastic BGA package (PBGA, 25x25 mm). 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.

MPC859TVR100A - 100MHz PowerQUICC MPC8xx MPU, 357-PBGA | NXP

The NXP (formerly Freescale) MPC859TVR100A is a PowerQUICC MPC8xx integrated communications-controller microprocessor combining a 32-bit Power Architecture core running at 100 MHz with on-chip peripheral subsystems, housed in a 357-pin PBGA package (25 mm x 25 mm). 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 NXP Semiconductors MPC859TVR133A is a 133 MHz PowerQUICC integrated communications-controller MPU built on a 32-bit Power Architecture core, packaged in a 357-ball PBGA (25x25 mm). It integrates a communications processor module, system integration unit, and peripherals in a single die for embedded networking and control applications. This part targets legacy industrial, telecom, and routing designs where long-term supply and field reliability are critical. A PowerQUICC (Quad Integrated Communications Controller) is a category of NXP/Freescale microprocessors that combine a Power Architecture CPU core with specialized communications peripherals - typically multi-channel SCCs (Serial Communication Controllers), an FCC (Fast Communications Controller), an SPI, an I2C, an IDMA controller, and a PCMCIA interface. In the broader product taxonomy it sits inside: microprocessor -> embedded MPU -> communications processor -> SoC (System-on-Chip for networking). Key features of the MPC859TVR133A include a 133 MHz CPU core, 32-bit data path, on-chip 8 KB instruction and 8 KB data caches, four SCC channels, two SMC channels, one FCC, dedicated peripheral interfaces (SPI, I2C, PCMCIA), and a CPM (Communications Processor Module) that offloads protocol handling from the CPU. 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.

It is designed for embedded communications and networking controller applications such as routers, switches, DSLAMs, and telecom line cards, where deterministic protocol processing is required alongside general-purpose CPU control. An MPU (Microprocessor Unit) integrates a CPU core with peripheral and memory subsystems on a single die, while a PowerQUICC device extends this concept with a dedicated RISC-based communications processor that offloads DMA, HDLC, Ethernet, ATM, and serial protocol handling from the main CPU core. Within the broader taxonomy, PowerQUICC sits under Power Architecture SoC -> microprocessor -> embedded processor -> semiconductor, and combines deterministic I/O with a familiar programming model that simplifies firmware portability from earlier MPC8xx designs. The MPC860DECZQ50D4 features include a single 32-bit core running at 50 MHz, dual 10 Mbps Ethernet MACs with MII interfaces, four serial communications controllers (SCCs), two serial management controllers (SMCs), a 4-channel DMA controller, and a memory controller supporting DRAM, SRAM, EPROM, Flash, and user-programmable machines. The 'C' suffix denotes a 4 Kbyte instruction cache, 4 Kbyte data cache, and integrated memory management unit (MMU) with translation tables, enabling protected-memory operating systems such as VxWorks and embedded Linux. Power consumption is reduced relative to legacy MPC860 designs through clock gating and selective peripheral power-down. The part targets telecom infrastructure, industrial control, and embedded networking designs where deterministic communications throughput is required. Operating temperature range is -40 C to +95 C, suitable for industrial-grade enclosures but not full automotive. The 'D4' suffix indicates a tray packaging variant of the 357-PBGA, which is a lead-free but non-RoHS lead-bearing BGA per long-standing PowerQUICC data sheets. Designers should consider the device's EOL lifecycle status, the need for legacy compiler toolchains, and the continued availability of NXP/Freescale reference BSPs. The MPC860DECZQ50D4 is appropriate for sustainment of existing designs and for new designs where long-term support outweighs raw clock speed requirements. Compared to a 50 MHz PowerQUICC, modern Cortex-R or Cortex-A SoCs deliver 10x to 100x the DMIPS per watt but require revalidation of firmware, drivers, and timing budgets.

Key specifications include 80 MHz maximum core frequency, 32-bit internal data path, single-core architecture, and a 357-pin PBGA (25x25 mm) surface-mount package. Power consumption, exact memory map, and peripheral count should be confirmed against the manufacturer datasheet because this variant is end-of-life and datasheet revision documents are the only authoritative source. Typical applications include telecom line cards, ISDN adapters, industrial routers, VoIP gateway controllers, and legacy networking equipment where a deterministic PowerPC core with integrated CPM (Communications Processor Module) replaced an external ASIC. The 357-PBGA package requires multi-layer PCB design with controlled-impedance traces and a substantial thermal copper pour. When designing with this EOL part, verify long-term availability through authorized distributors and review NXP's Product Change Notice documentation. The 357-ball PBGA demands reflow profile control within JEDEC J-STD-020 parameters and X-ray inspection post-assembly because the large array is not visually inspectable.

MPC860DEZQ50D4 - PowerQUICC MPU 50MHz 357-BGA | NXP

The NXP MPC860DEZQ50D4 is a PowerQUICC MPC8xx family 32-bit integrated communications microprocessor running at 50 MHz core clock, housed in a 357-ball PBGA package. It combines a Power Architecture embedded core with the CPM (Communications Processor Module) that supplies dedicated hardware for HDLC, Ethernet (10/100 Ethernet MAC), PCMCIA, and serial channel controllers. The device integrates a system-level peripheral set including timers, an interrupt controller, memory controllers, and a 32-bit data bus, enabling single-chip designs for networked and telecom equipment. A PowerQUICC device is a member of the communications-processor family that merges a general-purpose RISC microprocessor core with a dedicated communications engine on the same die. In the broader taxonomy it sits at: PowerQUICC -> communications microprocessor -> microprocessor unit (MPU) -> integrated circuit -> semiconductor. This category was developed specifically for embedded networking and telecom control-plane designs where deterministic I/O handling, multi-protocol serial framing, and low BOM cost outweigh raw computational throughput. Key features include a 50 MHz core, integrated 10/100 Ethernet MAC, HDLC/SDLC channel support, PCMCIA interface, a flexible memory controller for DRAM/SRAM/Flash, an interrupt controller with multiple priority levels, and a peripheral set that covers serial, parallel, and timer functions. The device integrates virtually every block required to build an xDSL/Cable modem, router, bridge, or industrial serial controller, eliminating external protocol-bridge chips. Architecturally, the MPC860 uses a 0.32 µm CMOS process with separate instruction and data paths for the embedded Power core, while the CPM offloads DMA-driven serial framing, freeing the core for routing and control-plane code. The chip is delivered in a 357-ball Plastic BGA (PBGA) with 25x25 mm body, providing adequate escape routing for the wide external bus while staying within a manageable PCB footprint. Typical applications include xDSL/cable modem control plane, ISDN router termination, T1/E1 channel banks, industrial serial concentrators, and embedded networking appliances where the integrated Ethernet MAC and HDLC channels remove the need for an external bridge IC. Designers should note the 3.3 V I/O supply requirement, the need to honor all 357 BGA balls including unused supply pins, and the importance of following the reference manual's reset and configuration sequence for proper CPM bring-up. This page consolidates distributor pricing, verified drop-in alternatives, and practical design notes that go beyond the bare manufacturer datasheet to help engineers and procurement teams evaluate this legacy PowerQUICC part.
