MPC862PVR100B

MPC862PVR100B - 100MHz PowerQUICC MPU 357-BGA | NXP

The NXP MPC862PVR100B is a 32-bit PowerQUICC microprocessor from the MPC8xx family, integrating a PowerPC core with a Communications Processor Module (CPM) on a single die. It operates at 100 MHz, runs from a 3.3 V supply, and is housed in a 357-pin PBGA package measuring 25 mm x 25 mm. The device is fabricated on a 0.32 um CMOS process and is offered in tray packaging for industrial production lines. A PowerQUICC microprocessor is a system-on-chip that combines a high-performance PowerPC integer unit with a RISC-based communications processor module. The architecture is designed for embedded networking and telecom applications where deterministic I/O handling, multi-protocol serial support, and ATM/HDLC processing must coexist with a general-purpose control plane. MPC8xx family members occupy a position in the broader Power Architecture hierarchy: PowerPC embedded CPU -> PowerQUICC family -> MPC8xx generation -> communications processor class. Key features of the MPC862PVR100B include 100 MHz core frequency, on-chip CPM with support for Fast Ethernet, HDLC, UART, I2C, IrDA, and SPI peripherals, dual 10/100 Ethernet MACs, and a 32-bit address/data bus. The device provides 32 general-purpose timers, an interrupt controller, and a memory controller that supports SDRAM, ROM, Flash, and external peripherals through a unified bus interface. The integrated CPM offloads protocol processing from the core, allowing the PowerPC CPU to run application code while dedicated RISC engines handle DMA channels, serial protocols, and packet routing. This dual-engine approach is what historically distinguished the MPC8xx family from simpler single-core microcontrollers and made it popular in routers, DSLAMs, and industrial control equipment throughout the 2000s. Typical applications include SOHO routers, integrated access devices, ISDN terminal adapters, industrial serial gateways, and legacy telecom infrastructure where ATM, HDLC, and multi-channel UART handling are required. The wide peripheral integration reduces external chip count and PCB area. When designing with this part, ensure proper thermal management because the 357-pin PBGA package concentrates dissipation in a relatively small die. Decouple each power pin with 0.1 uF ceramic capacitors and use a 4-layer PCB with continuous power and ground planes. The 3.3 V supply must remain within the 3.135 V to 3.465 V window under all transient conditions.

MPC862PVR66B

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

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

MPC862PVR80B

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

The NXP (formerly Freescale/Motorola) MPC862PVR80B is a 32-bit PowerQUICC integrated communications processor (MPC8xx family) operating at 80 MHz, housed in a 357-ball PBGA package measuring 25 x 25 mm. It integrates a PowerPC core with the CPM (Communications Processor Module) and is fabricated on a 0.32 micrometer CMOS process with a 3.3 V core I/O supply. An MPU (Microprocessor Unit) in the PowerQUICC family combines a general-purpose PowerPC integer core with dedicated on-chip peripherals designed for networking and telecom equipment. The MPC8xx sits in the hierarchy above single-core MCUs and below higher-end PowerQUICC II/III devices, and it typically serves as the central controller in routers, bridges, and remote-access equipment where both RISC processing and serial-protocol offload are required. Key features include the 80 MHz core frequency, integrated CPM with support for multiple HDLC/SCC channels, 32-bit PowerPC architecture, and the 357-PBGA surface-mount package. The device integrates a 4-channel DMA controller, timers, a memory-management unit, and a 60x-compatible bus for external memory interfacing. Power consumption is dominated by the 3.3 V supply rail and scales with clock and CPM activity. Architecturally, the MPC862PVR80B separates control-plane processing from data-plane protocol handling: the PowerPC core runs the application stack while the CPM handles serial-channel DMA, HDLC framing, and ATM SAR. The 0.32 micrometer process gives reasonable static leakage for an embedded device of its era, and the 357-PBGA footprint provides ample ground/thermal balls for board-level dissipation. Typical applications include integrated access devices, LAN/WAN routers, frame-relay access equipment, xDSL modems, and industrial serial-control gateways. The combination of an embedded CPU plus the CPM makes it well suited to multi-protocol bridging tasks where a discrete CPU + ASIC solution would be too large. When designing with this MPU, plan the PCB for the 25 x 25 mm BGA land pattern with at least 6 layers to route the 60x bus cleanly, and pay attention to the 3.3 V supply decoupling near each power ball. Because the part is mature, source through franchised distributors or authorized aftermarket partners to mitigate counterfeit risk. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on a single vendor page, and pulls together the known same-family drop-in members and BGA-357 equivalents an engineer would consider for second-source qualification.

MPC862PZQ66B

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

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

Key features include a 32-bit PowerPC core at 80 MHz, an on-chip CPM supporting serial channels, ATM, Fast Ethernet, and HDLC/PPP protocols, plus memory controllers for SDRAM, DRAM, and burst-mode flash/ROM. The 357-PBGA package provides a robust thermal path for sustained industrial workloads. The device targets -40C to +95C ambient (industrial) operating ranges per the family documentation. Typical applications for the MPC862TCVR80B include legacy enterprise networking equipment, ISDN/ADSL modem gateways, industrial serial routers, and long-lifecycle embedded control systems. Its integration of CPU and CPM reduces BOM count versus a discrete CPU + companion communications ASIC. Designers moving to RoHS-compliant revisions can use this part as a drop-in upgrade path on existing PBGA footprints. Designers should verify the specific datasheet revision before PCB layout because BGA ball assignments are exact and any pin-map error requires board rework. Use the 357-PBGA land pattern exactly as specified in the manufacturer mechanical drawing, and follow the power-decoupling guidance for the VDDHV/VCC pins. Engineers considering migration should review the broader PowerQUICC III (MPC83xx) family for forward-compatible designs.

MPC866TZP133A

MPC866TZP133A - MPC8xx PowerQUICC 133MHz BGA Processor | NXP

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

It integrates a Power Architecture core with on-chip communications peripherals originally tuned for networking and telecom equipment such as routers, SOHO gateways, and protocol bridges. The device operates from a 3.3 V supply and is specified over an industrial -40C to +100C junction range, making it suitable for thermally constrained embedded enclosures. A microprocessor (MPU) is the highest-level processing element in an embedded system hierarchy: MPU -> microcontroller (MCU) -> SoC -> ASIC. PowerQUICC MPUs pair a PowerPC-style core with a system integration unit containing DMA, timers, serial comms, and memory controllers, which historically positioned the family as a single-chip networking engine. Within NXP's portfolio, the MPC870 sits in the lower-frequency MPC8xx tier, aimed at applications where deterministic serial and Ethernet comms matter more than raw GHz-scale compute. Key features include a single Power Architecture 32-bit core, integrated 10/100 Ethernet MAC support, multiple UARTs, I2C, SPI, and a peripheral subsystem designed for sustained I/O throughput. The 256-ball PBGA package exposes the external memory bus plus peripheral interfaces, while the die itself is fabricated on a 0.18 micrometer CMOS process for predictable power draw at 3.3 V. The MPC870CZT66 is the speed-grade suffix 'ZT66' variant (66 MHz) of the MPC870 family, distinct from higher-clocked ZT80 or lower-clocked VR66 grades. Typical applications include industrial routers, ISDN/DSL modem bridges, remote access concentrators, factory automation controllers, and legacy telecom line cards where the MPC8xx ecosystem still ships in volume. Engineers designing new boards around this part should pair it with NXP-recommended SDRAM and flash topologies and reference the MPC8xx hardware specification for bus timing. When designing with this device, ensure the external memory bus termination and decoupling network match the MPC8xx reference design; signal integrity on the 66 MHz bus must be verified with the board manufacturer. Firmware developed on this MPU typically relies on the PowerQUICC U-Boot port and Linux BSP for the MPC8xx family.

In each scenario the integrated CPM removes the need for a separate network processor. Designers should plan thermal dissipation through the top-side PBGA thermal pad and verify DDR/SDRAM timing margins against the 133 MHz system bus; a buffered DIMM topology is recommended when more than one memory device is used.
