MPC8379VRAGD - 400MHz PowerQUICC II Pro MPU | NXP | 689-BGA
部品番号: MPC8379VRAGD ✗ 生産終了MPC8379VRAGD 概要
A PowerPC microprocessor is a reduced-instruction-set computing (RISC) processor originally designed by the AIM alliance (Apple, IBM, Motorola) and now maintained by NXP for embedded applications. PowerQUICC II Pro extends the original PowerQUICC architecture with integrated peripherals for communications processing, encryption acceleration, and DDR memory control. Within the hierarchy, a microprocessor belongs to the broader category of processors, alongside microcontrollers (MCU), DSPs, and application processors. The MPC83xx series specifically targets SOHO routers, industrial control, and networked storage.
Key features of the MPC8379VRAGD include a 400 MHz e300c4s core, single-core 32-bit operation, integrated DDR memory controller, dual 10/100/1000 Ethernet MACs, USB 2.0, PCI Express, and security acceleration engines on the E-variant (absent on the standard MPC8379VRAGD). The IC operates from a 1 V core supply voltage and integrates common networking peripherals, reducing external component count in router, gateway, and NAS designs.
The architecture pairs the e300c4s execution core with a QUICC Engine communications processor module for offloading packet processing, enabling line-rate throughput without burdening the host CPU. This heterogeneous dual-engine design is the hallmark of the PowerQUICC II Pro family and is often selected where deterministic networking performance is required alongside general-purpose Linux or VxWorks application hosting.
Typical applications for MPC8379VRAGD include small-office/home-office (SOHO) routers, networked attached storage (NAS) controllers, industrial gateways, protocol converters, and embedded Linux appliances. The wide peripheral integration also makes it a candidate for printer controllers and point-of-sale terminals requiring both networking and general-purpose compute.
When designing with this device, ensure the PCB layout follows the TEPBGA II 31 x 31 mm land pattern with matched-impedance routing for DDR memory and Ethernet signals. Power sequencing of the 1 V core and 3.3 V I/O rails must follow the order specified in the manufacturer datasheet to avoid latch-up during power-up.
This page consolidates distributor pricing, drop-in alternative BGA parts, and practical design considerations not found in a single datasheet, giving engineers an actionable comparison reference for MPC8300-series microprocessors.

主な用途
MPC8379VRAGD の用途: 6 件s: SOHO Router and Small-Business Gateway, Network-Attached Storage (NAS) Controller, Industrial Protocol Gateway, Embedded Linux Appliance, Printer and MFP Controller, Point-of-Sale (POS) Terminal.
SOHO Router and Small-Business Gateway
The MPC8379VRAGD fits SOHO router designs because its 400 MHz e300c4s core delivers enough compute for routing, NAT, and firewall workloads while the integrated dual Gigabit Ethernet MACs handle WAN-LAN bridging without external PHY bridge chips. The QUICC Engine offloads packet classification from the host CPU, sustaining line-rate throughput on GbE interfaces. Compared with a discrete MPU plus GbE switch solution, the MPC8379VRAGD's integrated peripherals reduce BOM count and PCB area, while its 689-TEPBGA II package preserves thermal headroom in fanless router enclosures. Power consumption at full CPU utilization is governed by the 1 V core rail and scales with traffic load.
おすすめ
Network-Attached Storage (NAS) Controller
In NAS controllers for small-business and home-server products, the MPC8379VRAGD runs the storage management stack (SMB/NFS/iSCSI) on its 400 MHz e300c4s core while the integrated SATA and GbE interfaces attach directly to disk drives and the network. The DDR memory controller supports the large working sets required by caching and RAID metadata operations. Compared with a general-purpose ARM Cortex-A MPU, the MPC8379VRAGD's deterministic QUICC Engine packet handling delivers predictable I/O latency for file-serving workloads. Its 689-TEPBGA II package requires careful PCB thermal design when fully loaded with multiple SATA drives.
おすすめ
Industrial Protocol Gateway
The MPC8379VRAGD is well-suited for industrial gateways translating Modbus, PROFINET, EtherNet/IP, or serial protocols between field devices and Ethernet backbones. Its 32-bit PowerPC e300c4s core at 400 MHz runs real-time operating systems (RTOS) or embedded Linux to host protocol stacks, while the integrated Ethernet and serial peripherals eliminate external bridge ICs. Industrial-grade parts can operate across extended temperature ranges per the manufacturer datasheet. The 689-TEPBGA II footprint with exposed pad enables reliable thermal performance in sealed industrial enclosures, providing years of maintenance-free operation.
おすすめ
Embedded Linux Appliance
The MPC8379VRAGD hosts embedded Linux distributions targeting industrial appliances such as building automation controllers, security panels, or remote sensor aggregation hubs. Its 400 MHz e300c4s core provides the headroom required for full Linux kernel, file system, and networking stack while the integrated DDR controller supports the larger memory footprint typical of Linux deployments. The 689-TEPBGA II package is footprint-compatible across the MPC8300 family, simplifying board variants for different feature mixes. Boot is typically from NOR flash or SPI with main image on NAND or eMMC behind a local bus.
おすすめ
Printer and MFP Controller
Multi-function printer (MFP) controllers rely on the MPC8379VRAGD's combination of processing throughput and peripheral integration to drive the print engine, scan subsystem, and network interfaces simultaneously. The e300c4s core at 400 MHz handles job queuing, image rendering, and PCL/PostScript interpreters, while the integrated Ethernet and USB peripherals provide the connectivity users expect from networked office equipment. Compared with discrete processor-plus-controller chip designs, the integrated architecture lowers BOM cost and simplifies EMC compliance by reducing high-speed signal traces. Thermal design must account for the 689-TEPBGA II package.
おすすめ
Point-of-Sale (POS) Terminal
POS terminals benefit from the MPC8379VRAGD's deterministic real-time performance and rich peripheral set, which together manage barcode scanners, receipt printers, payment terminals, and Ethernet back-office connectivity. The 400 MHz PowerPC core runs the terminal application stack and encryption routines for payment data, while DDR memory and integrated GbE MACs sustain fast transaction throughput. The 689-TEPBGA II footprint provides a stable mechanical platform for the ruggedized chassis typical of retail POS hardware. Operating temperature and reliability targets align with industrial-grade MPU variants of this family.

設計ノート
The 689-TEPBGA II (31x31 mm) package requires careful PCB thermal management because the die is large and the package exposes its pad through the bottom for heat dissipation. Estimated: at 1 GHz-equivalent worst-case CPU utilization on the 1 V core, expect 4-6 W dissipation that must be conducted through the BGA ground/power plane stack-up. Use a 4-layer board with at least two solid internal ground planes stitching under the part, and follow the manufacturer thermal via array pattern under the exposed pad. Verify junction temperature against the system thermal budget with the manufacturer theta_JA value.
Route matched-impedance differential pairs (Ethernet, PCIe) per the manufacturer IBIS models and reference design. Estimated: a 100-ohm differential impedance with 5 mil trace on a 4-layer stack-up typically requires a 6-8 mil dielectric to the nearest reference plane. The DDR2 memory controller needs tight length matching across the address/command and clock groups; consult the manufacturer DDR2 design guide for tJITTER and skew budgets.
Do not power the 1 V core rail before the 3.3 V I/O rail, otherwise the I/O buffers may be back-driven through the ESD structures and latch-up can occur. Decoupling must include high-frequency ceramic (0.1 uF X7R) on every power pin plus bulk polymer or ceramic capacitors near the BGA edges. Verify boot mode configuration pins are pulled to the correct logic levels before the POR signal is released, or the part may fail to start. Estimated: a 10 ms reset-to-clock delay is typical before boot ROM sampling takes effect.
