MPC8275CVRMIBA - PowerQUICC II 266MHz SoC MPU, 516-PBGA | NXP
MPN: MPC8275CVRMIBA ⚠ آخر فرصة للشراءMPC8275CVRMIBA نظرة عامة
A PowerQUICC II processor is a system-on-chip (SoC) communications processor that combines a PowerPC host CPU with a dedicated CPM supporting HDLC, Ethernet (10/100 Mbit), ATM/UTOPIA, USB, I2C, SPI, and PCI. It sits above simple microcontrollers and below full application processors in the embedded hierarchy, and is classified as an integrated microprocessor (MPU) within power-management-adjacent embedded silicon.
Key features include 505.4 MIPS sustained performance, integrated DRAM/SDRAM memory controller, dual 10/100 Ethernet MACs, PCI 2.2 interface, USB 1.1 host/client, HDLC TDM channels, UTOPIA PHY interface, and an external bus supporting up to 133 MHz operation. The CPM runs autonomously and handles DMA, protocol framing, and time-division multiplexing without host intervention.
The MPC8275CVRMIBA is architecturally positioned between the lower-frequency MPC8270 (266 MHz-class) and the higher-throughput MPC8280, giving designers a balanced choice for cost-sensitive mid-range routers, DSLAM line cards, and industrial control gateways where deterministic protocol handling matters more than raw CPU throughput.
Typical applications include wired networking routers and switches, telecom line cards (xDSL, ISDN, T1/E1), industrial serial gateways, VoIP media gateways, and embedded control platforms requiring deterministic multi-protocol I/O. The 516-PBGA package requires careful PCB layout with multiple power and ground planes for thermal management.
When designing with this device, plan a 4- to 6-layer PCB with a continuous ground plane beneath the BGA and a minimum 1 oz copper inner layer for power distribution. Decouple each power pin with 100 nF X7R placed within 5 mm of the ball. Observe the 266 MHz core clock and 133 MHz external bus skew budgets specified in the NXP hardware design checklist.

التطبيقات النموذجية
MPC8275CVRMIBA مناسب لـ 6 التطبيقs: Wired Networking Router / Switch, xDSL / ISDN Line Card, Industrial Serial-to-Ethernet Gateway, VoIP Media Gateway, SCADA / Industrial Automation Controller, Embedded Control Platform with Deterministic I/O.
Wired Networking Router / Switch
The MPC8275CVRMIBA's integrated dual 10/100 Ethernet MACs and PCI 2.2 interface make it well suited for small-to-mid-port fixed-configuration routers and L2/L3 access switches. The RISC CPM offloads Ethernet framing, HDLC, and DMA, allowing the 266 MHz PowerPC core to focus on routing tables, ACLs, and management-plane code, with the 516-PBGA package offering ample I/O for PHY and switch-fabric connectivity. Unlike a software-only SoC, the CPM keeps forwarding latency deterministic under bursty traffic.

xDSL / ISDN Line Card
Telecom line cards built on the MPC8275CVRMIBA leverage the CPM's UTOPIA and HDLC channels for ATM/DSL framing and ISDN PRI/BRI signalling. The integrated SDRAM controller simplifies connection to TC-layer memory, and the industrial -40 C to +105 C rating permits deployment in outdoor DSLAM cabinets. Compared with discrete framers, the CPM reduces BOM cost while maintaining TDM timing accuracy demanded by legacy PSTN equipment.
موصى به
Industrial Serial-to-Ethernet Gateway
The MPC8275CVRMIBA is a strong fit for industrial gateways that bridge legacy RS-232/RS-485 serial lines, HDLC field buses, and Modbus RTU onto Ethernet/IP or MQTT clouds. The CPM's HDLC and serial channels handle deterministic protocol timing while the host CPU runs the application layer. The -40 C to +105 C rating and the 516-PBGA's mechanical robustness suit factory-floor cabinets and outdoor enclosures.
موصى به
VoIP Media Gateway
VoIP media gateways benefit from the MPC8275CVRMIBA's combination of HDLC TDM channels for PSTN interworking and Ethernet MACs for SIP/RTP transport. The CPM's time-division multiplex engine maintains voice-sample timing alignment across multiple E1/T1 spans without host CPU intervention. The 266 MHz core has sufficient headroom for G.711/G.729 codec handling on a small-to-medium port count.
موصى به
SCADA / Industrial Automation Controller
SCADA controllers built on the MPC8275CVRMIBA use its PCI bus for SCADA I/O cards, Ethernet for plant-wide connectivity, and the CPM's serial channels for legacy Modbus, DNP3, or IEC 60870-5 links. The industrial temperature range, deterministic CPM timing, and long-life support typical of PowerQUICC silicon make it attractive for utility and process-control installations with 15-20 year service expectations.
موصى به
Embedded Control Platform with Deterministic I/O
For embedded control platforms requiring deterministic multi-protocol I/O, the MPC8275CVRMIBA pairs a Linux-capable 266 MHz PowerPC core with a CPM capable of handling SPI, I2C, USB 1.1, HDLC, and PCI concurrently. The 516-PBGA package supports the bus widths needed for external glue-less peripherals. The CPM's dedicated RISC engine ensures timing-critical peripherals do not stall the host CPU under load.

ملاحظات التصميم
Use a 6-layer PCB for the MPC8275CVRMIBA with a continuous ground plane beneath the 516-PBGA and dedicated power planes for the 1.5 V core and 3.3 V I/O rails. Place 100 nF X7R decoupling capacitors within 5 mm of every power pin and add bulk polymer or tantalum capacitors near each power-plane entry. The BGA thermal pad requires thermal vias to inner copper for heat spreading; the 266 MHz core dissipates roughly 1.5-2 W depending on CPM utilization.
Route the DDR SDRAM interface to the MPC8275CVRMIBA with controlled-impedance traces (typically 50 ohm single-ended) and matched lengths to within 25 mils for clock, address, and command signals. Keep the DDR reference plane unbroken and provide proper termination. The PCI bus signals should be routed to within the 2.5 inch guideline specified in the NXP hardware design checklist to avoid signal-integrity violations at 66 MHz.
Verify the exact part suffix when sourcing: the 'CVRMIBA' suffix indicates 266 MHz, industrial temperature, and the standard silicon revision. Earlier 'VRMIBA' or 'CZUPIEA' suffixes may have different CPM feature sets. Because the part is in Last Time Buy, Rochester Electronics and authorized brokers are reliable last-source channels; avoid grey-market vendors to reduce counterfeit risk.
