MPC852TCVR100A 概要
An MPU, or microprocessor unit, is the central processing element of an embedded system; in the broader taxonomy, it sits above a microcontroller (MCU) and below a system-on-chip (SoC), handling complex control-plane tasks with an external memory bus and peripherals. The MPC852T family is part of NXP's (formerly Freescale / Motorola) PowerQUICC line, which integrates a PowerPC core with a separate communications processor module (CPM) to offload networking and serial I/O tasks.
Key features include 100 MHz core speed, 3.3 V I/O operation with a 1.8 V internal core voltage, integrated CPM for Ethernet and serial communications, integrated timers and interrupt controller, and a 32-bit external memory bus supporting DRAM, SRAM, and ROM. The 256-PBGA package exposes the full 32-bit data bus plus dedicated Ethernet, SCC, and other peripheral pins. Operating temperature range spans -40 C to +100 C, supporting industrial and extended-commercial environments.
Architecturally, the MPC852T pairs a 32-bit PowerPC core with the CPM coprocessor that handles DMA-driven Ethernet MACs, serial communications controllers (SCCs), serial management controllers (SMCs), and a USB interface. The dual-engine approach offloads the main core from packet processing, delivering deterministic throughput for telecom line cards, routers, and industrial control nodes. The 0.18 micrometer process allows the 100 MHz operation at modest power consumption for its class.
Typical applications include Ethernet-to-Ethernet line cards, industrial routers and protocol bridges, telecom control-plane processors, factory automation controllers, and legacy PowerQUICC designs where software compatibility with the MPC860 family is required. The integrated CPM makes it a natural choice for any design requiring deterministic serial or Ethernet throughput alongside a general-purpose CPU.
When designing with this part, note that NXP has marked the MPC852T family for end-of-life per the official product page, so new designs should evaluate active PowerQUICC II (MPC82xx) or QorIQ successors. Existing designs should consider last-time-buy stocking and verify pin compatibility of any proposed cross-reference against the original 256-PBGA layout.
This page synthesizes distributor pricing, drop-in PowerQUICC alternatives, and end-of-life replacement guidance not found in a single datasheet, supporting engineers planning either new designs or field replacements.

主な用途
MPC852TCVR100A の用途: 6 件s: Ethernet Line Card Controller, Industrial Router and Protocol Bridge, Telecom Control-Plane Processor, Factory Automation Controller, Legacy PowerQUICC Design Maintenance, Networked Embedded Control Node.
Ethernet Line Card Controller
The MPC852TCVR100A's integrated CPM with Ethernet MACs and the 100 MHz Power Architecture core make it well suited for Ethernet line-card designs in legacy telecom and enterprise switching equipment. With 3.3 V I/O compatibility, a 32-bit external memory bus for SDRAM buffering, and deterministic DMA-driven packet handling, the part can sustain wire-speed Ethernet bridging without CPU saturation. Placed as the main control-plane processor on a line card, it pairs with external PHYs via MII/RMII and routes processed frames to backplane fabrics. Unlike a generic MCU, the dedicated CPM offloads protocol processing, freeing the core for routing table management and management-plane tasks.
おすすめ
Industrial Router and Protocol Bridge
Industrial routers and protocol bridges benefit from the MPC852TCVR100A's combination of Ethernet ports, serial channels (SCC/SMC), and the 32-bit Power Architecture core for routing and protocol conversion tasks. The 100 MHz core delivers enough headroom for TCP/IP stack processing, while the CPM handles serial framing for industrial protocols such as Modbus, Profibus, or serial-Ethernet bridging. Operating from -40 C to +100 C, the part tolerates factory-floor thermal environments. Designers typically pair it with external SDRAM for packet buffers and external flash for firmware storage, with the 32-bit memory bus supporting both.
おすすめ
Telecom Control-Plane Processor
The MPC852TCVR100A is a classic choice for telecom control-plane processors in legacy equipment such as DSLAMs, base station controllers, and central-office line cards. The deterministic CPM, hardware-backed DMA channels, and 32-bit memory bus with SDRAM support meet the latency and throughput requirements of control-plane traffic. Operating voltage of 3.3 V I/O with 1.8 V core simplifies power tree design using standard LDO regulators. For new designs, the PowerQUICC II (MPC82xx) family is recommended, but for service and spares, the MPC852TCVR100A continues to deliver the required deterministic performance.
おすすめ
Factory Automation Controller
Factory automation systems using the MPC852TCVR100A leverage its combination of Ethernet connectivity, multiple serial channels, and the 32-bit Power Architecture core for PLC-style control and SCADA communications. The wide -40 C to +100 C operating range allows deployment in unconditioned factory cabinets, while the CPM offloads real-time serial protocol handling from the main core. Typical implementations connect the part to digital I/O expansion via the external bus, to operator panels via Ethernet, and to motor drives via SCC/SMC serial links. Power dissipation at 100 MHz is modest for the BGA package, simplifying thermal design in sealed enclosures.
おすすめ
Legacy PowerQUICC Design Maintenance
Many existing designs based on the MPC860 family and related PowerQUICC parts continue to ship in volume, requiring service replacements and last-time-buy stocking of the MPC852TCVR100A. The part's pin-compatibility with other MPC852T variants (MPC852TVR80A, MPC852TCZT100A) allows field replacements to use either the original 100 MHz part or the slower/thermal-grade siblings depending on availability. Software compatibility across the PowerQUICC MPC8xx family means firmware does not need modification when swapping variants. Engineers should verify board revision compatibility and stock sufficient inventory ahead of EOL depletion.
おすすめ
Networked Embedded Control Node
Networked embedded control nodes that need a 32-bit processor with integrated Ethernet and serial I/O find the MPC852TCVR100A a fit for designs requiring more horsepower than typical 8-bit or 16-bit MCUs while keeping a single-chip BOM. The 100 MHz Power Architecture core handles control logic, the CPM manages Ethernet and serial traffic, and the 32-bit memory bus supports external SDRAM for buffering and flash for firmware. The 256-PBGA package suits compact controller boards, though it requires careful PCB layout and BGA assembly capability. For new designs, weigh the EOL status against active alternatives such as NXP's Kinetis or i.MX RT families.

設計ノート
The 256-PBGA package requires careful PCB thermal design. At 100 MHz core speed with 3.3 V I/O and 1.8 V core, total power dissipation is moderate for the class, but the BGA package depends on thermal vias to inner copper planes for heat removal. Provide an array of thermal vias under the exposed die-attach paddle, connect inner ground planes, and avoid concentrating high-power components directly above the BGA on the opposite board side. For sealed enclosures, derate junction temperature by at least 15 C below the +100 C maximum to account for thermal gradient.
BGA escape routing demands microvia or HDI PCB technology. Fan-out the 256 balls on at least a 4-layer stackup with continuous ground and power planes directly beneath the BGA. Keep trace lengths matched for the 32-bit external memory bus to SDRAM to within 50 mils; use series termination resistors on heavily-loaded address and data lines. Place SDRAM as close to the BGA as the breakout allows to minimize stub lengths and signal-integrity issues at the 100 MHz bus speed.
Do not assume the MPC852TCVR100A and the older MPC860 family parts are interchangeable despite the shared PowerQUICC lineage; verify the specific BGA pin map and CPM revision against the original design. Because the part is EOL per the NXP product page, lock in last-time-buy stock before allocation closes, and validate any independent-distributor source for authenticity. Confirm boot mode strap pin states and reset timing against the datasheet before substituting a sibling part such as MPC852TVR80A or MPC852TCZT100A, even though they share the same package.
