MPC852TCVR80A 概要
A PowerQUICC (pronounced 'power-quick') processor is a family of integrated communications microcontrollers designed for networking infrastructure, telecom equipment, and embedded control. Within the broader semiconductor taxonomy, a PowerQUICC MPU sits between a microcontroller (MCU) and a high-performance microprocessor (MPU), classified as: PowerQUICC -> MPU -> integrated communications processor -> networking SoC -> semiconductor. The MPC8xx family is the predecessor generation to the MPC82xx and MPC83xx PowerQUICC II/III lines, optimized for low-power WAN, LAN, and DSLAM line-card applications.
Key features include 80 MHz core and CPM operation, an integrated 10/100 Mbps Ethernet MAC, dual UART, dual I2C, SPI, and PCI interface support. The hardware-accelerated encryption engine (SEC) accelerates DES, 3DES, AES, and MD-5/SHA-1 hashing, while the CPM offloads DMA and protocol framing from the core. Memory interfaces include support for SDRAM, Flash/EPROM, and a 32-bit local bus, allowing flexible boot and storage topologies.
The device is fabricated in a 0.18 micron CMOS process and rated for industrial temperature operation. It supports NXP's product longevity program with assured supply for a minimum of 10 years from launch, making it a reliable choice for long-lifecycle networking and industrial equipment designs.
Typical applications include DSLAM line cards, integrated access devices, wireless base stations, industrial routers, and telecom control planes where deterministic CPM-managed I/O outperforms general-purpose processors. The 'TC' industrial temperature grade ensures operation in uncontrolled thermal environments such as outdoor enclosures.
A key design consideration is the 256-ball MAPBGA requiring multi-layer PCB (typically 6+ layers) with controlled-impedance routing for the memory and PCI buses. Designers should follow NXP application note AN2083 (MPC8xx Hardware Design Notes) for the recommended power decoupling, clock distribution, and reset sequencing; also note that the JTAG boundary-scan chain requires a BSDL file for production test.
This page synthesizes distributor pricing, drop-in alternatives within the MPC852 family, and practical design notes compiled from NXP's PowerQUICC reference designs that are not duplicated in the manufacturer's datasheet.

主な用途
MPC852TCVR80A の用途: 6 件s: DSLAM Line Card, Industrial Router and Gateway, Wireless Base Station Controller, Telecom Control Plane Processor, Network Print Server and Appliance, Industrial IoT Edge Gateway.
DSLAM Line Card
The MPC852TCVR80A is purpose-built for DSLAM line cards where deterministic CPM-managed packet I/O outperforms general-purpose processors. The integrated 10/100 Ethernet MAC, PCI bus, and UTOPIA interface support connect to ADSL/VDSL PHY devices, while the hardware-accelerated SEC (DES/3DES/AES) handles subscriber-side authentication. The 80 MHz core frequency delivers sustained throughput per line card without buffering, and the -40C to +85C industrial temperature grade allows deployment in outdoor or uncontrolled cabinet environments where ambient swings are common.
おすすめ
Industrial Router and Gateway
For industrial router designs, the MPC852TCVR80A integrates nearly every interface required: dual 10/100 Ethernet, dual UART (RS-232/485), I2C, SPI, and PCI. The hardware crypto engine accelerates IPsec/SSL VPN tunnels, while the 32-bit local bus connects SDRAM and Flash for routing-table and firmware storage. The PowerPC core plus CPM division of labor keeps the core free for routing protocols, NAT, and firewall state-machine work. With -40C to +85C operation and NXP's 10-year longevity commitment, this MPU is a strong fit for factory-floor and substation gateway deployments.
おすすめ
Wireless Base Station Controller
The MPC852TCVR80A is well-suited for 2G/3G wireless base-station controller applications due to its CPM offloading and deterministic interrupt latency. The dual UART links to RF transceiver front-ends, while the PCI bus connects to DSP cards handling baseband signal processing. The hardware crypto accelerator is critical for A3/A8 GSM ciphering and UMTS authentication. At 80 MHz, it can sustain multi-sector call-control messaging alongside traffic-channel switching; the industrial temperature grade and 10-year longevity program target telecom OEM procurement profiles.
おすすめ
Telecom Control Plane Processor
On the telecom control plane, the MPC852TCVR80A serves as a low-power management processor for SS7 signalling, SNMP, and OAM functions. The low 1.0-1.5 W typical power dissipation makes it viable in always-on control roles, while the PowerQUICC CPM handles serial and Ethernet housekeeping without burdening the PowerPC core. Designers can boot from a small parallel Flash, store configuration in SDRAM, and expose management via the integrated Ethernet MAC; the BGA-256 footprint and BSDL file support automated production test.
おすすめ
Network Print Server and Appliance
Embedded office appliances such as network print servers and protocol-conversion gateways benefit from the MPC852TCVR80A's USB-host-capable CPM and PCI expansion. The integrated 10/100 Ethernet, dual UART, and I2C peripherals directly drive printer engines, badge readers, or sensor peripherals without external glue logic. Running at 80 MHz with hardware crypto, the device also enables secure print-release workflows where authentication data is hashed on-chip. The 256-MAPBGA footprint supports compact appliance form factors.
おすすめ
Industrial IoT Edge Gateway
The MPC852TCVR80A is a robust choice for industrial IoT edge gateways aggregating Modbus, CAN, I2C, SPI, and serial sensor streams. The PowerPC core runs edge analytics while the CPM manages multiple serial channels in parallel, and the integrated Ethernet MAC uplinks aggregated data to the cloud. Hardware-accelerated AES protects telemetry-in-transit to the cloud, and the -40C to +85C industrial rating ensures operation in plant-floor cabinets. NXP's 10-year longevity program matches the long deployment horizon of industrial IoT installations.

設計ノート
The 256-ball MAPBGA at 1.27 mm pitch requires at least 6 PCB layers with microvia-in-pad technology for reliable assembly. Use a stack-up with dedicated power and ground planes adjacent to the BGA fanout. Per NXP application note AN2083 (MPC8xx Hardware Design Notes), trace lengths must be length-matched within 50 mils on the memory and PCI buses to avoid timing violations.
Estimate: at 80 MHz core with active CPM and crypto engine, total power dissipation is roughly 1.2 W from the 1.8 V core rail. Place 22 uF + 0.1 uF decoupling pairs within 100 mil of each core-supply ball, with additional bulk capacitance on the board edge. The 3.3 V I/O rail typically draws 200-300 mA; use a low-noise LDO such as NXP TLV1117-33 adjacent to the device to avoid PLL jitter.
Do not omit the external clock source with proper termination - the MPC852's PLL requires a clean 32 kHz-100 MHz reference with the bias components specified in the datasheet. Also confirm that HRESET is held low for a minimum of 100 us after both core and I/O rails reach regulation; this prevents the CPM from booting in an indeterminate state and avoids rare lockup scenarios.
コンプライアンス情報
RoHS compliant per NXP product page; halogen-free status to be confirmed via lot-specific CofC. Not AEC-Q100 qualified - this is an MPU for telecom and industrial networking, not automotive.
