MPC8272VRTIEA - PowerQUICC II, 400MHz, 516-FPBGA SoC MPU | NXP
MPN: MPC8272VRTIEA ✓ Hoạt độngMPC8272VRTIEA Tóm tắt
What is a PowerQUICC II processor? PowerQUICC II is a NXP/Motorola communications-processor family that integrates a PowerPC core with a RISC-based Communications Processor Module (CPM) optimised for fast peripheral and protocol processing. Within the broader taxonomy, it sits between a discrete microcontroller and an application processor: a PowerPC MPU -> embedded microprocessor -> communications SoC -> PowerQUICC II. The CPM offloads DMA, HDLC, Ethernet and ATM from the host core, which is why PowerQUICC II parts remained popular in legacy networking designs even after newer ARM SoCs arrived.
Key features of the MPC8272VRTIEA include: a 400 MHz G2_LE core, 16 Kbytes of instruction cache and 16 Kbytes of data cache with parity protection, an integrated 32-bit PCI bridge with up to 66 MHz operation, a USB 1.1 host/device controller, a multi-channel HDLC and Fast Ethernet MAC (UTOPIA L2 capable), and the SEC engine for DES/3DES/AES/SHA-1 acceleration. The device operates from a 1.5 V core supply with separate I/O rails, and supports 0 to 105 degrees C junction temperatures.
Architecturally, the MPC8272VRTIEA uses a two-bus system: the 64-bit PowerPC 60x system bus talks to external SDRAM and Flash, while an internal 32-bit local bus bridges peripherals. The CPM runs at a configurable ratio to the core, allowing designers to trade peripheral throughput against power dissipation. The SEC crypto-block is wired directly into the CPM to provide wire-speed IPsec/VPN throughput without loading the host core.
Typical applications include SME routers, integrated access devices, VoIP gateways, DSLAM line cards, industrial control planes and protocol bridges. The -40 C to +105 C industrial temperature grade makes this part suitable for outdoor and hardened enclosures as well as controlled server rooms.
Designers should evaluate the 516-FPBGA ball assignment and 27 x 27 mm PCB footprint early, because routing 32-bit parallel memory, PCI and an MII/UTOPIA interface simultaneously requires 4-to-6 layer PCB stack-ups with controlled-impedance traces. NXP provides a complete reference design (schematic, gerbers and U-Boot firmware) in the PowerQUICC II development kit, which is the recommended starting point for first-time users.
This page synthesises distributor pricing across DigiKey, Mouser and Octopart, suggests drop-in MPC8272 and MPC8247 family alternates when the 400 MHz speed grade is out of stock, and supplies PCB-layout and thermal notes that complement (but never replace) the manufacturer datasheet.

Ứng dụng tiêu biểu
MPC8272VRTIEA phù hợp cho 6 Áp dụngs: Small-to-Medium Enterprise (SME) Routers, DSLAM / Access Network Line Cards, VoIP Media Gateways, Industrial Control Planes and Protocol Bridges, Network-Attached Storage (NAS) Controllers, Wireless Backhaul and LTE Small-Cell Baseband.
Small-to-Medium Enterprise (SME) Routers
The MPC8272VRTIEA pairs the 400 MHz G2_LE core with the CPM's multi-channel HDLC and Ethernet engines, providing the throughput needed to route WAN traffic in SME routers without burning the host CPU. Hardware IPsec/SSL via the integrated SEC engine delivers wire-speed VPN, offloading what would otherwise require a separate crypto chip. Designers place the device between a 100/1000 Mbps PHY and the WAN DSL/cable modem; the 64-bit external memory bus feeds SDRAM for routing tables and connection state, while PCI exposes expansion slots for hardware encryption accelerators or wireless modules.
Được đề xuất
DSLAM / Access Network Line Cards
In DSLAM line cards the MPC8272VRTIEA's UTOPIA L2 interface talks directly to multi-PHY ADSL/VDSL front-ends without glue logic, and the CPM provides per-channel HDLC encapsulation and back-pressure. Running at 400 MHz, one device can service dozens of DSL lines, allowing a single line-card slot to handle hundreds of subscribers. The 32-bit PCI bus interconnects multiple line cards to an aggregation switch; the same 27 x 27 mm footprint used across the MPC8272 family lets designers reuse PCB artwork across 100/200/400 MHz SKUs.
Được đề xuất
VoIP Media Gateways
VoIP gateways require deterministic low-latency DSP control plus encryption for SIP/TLS and SRTP, which the MPC8272VRTIEA delivers through the G2_LE core for control-plane tasks and the SEC block for SRTP/AES payload encryption. The CPM handles TDM/HDLC/T1/E1 framing, freeing the core to run SIP stacks, codecs and PBX logic. The PCI interface provides a path to hardware DSP/TMS320 echo-canceller cards; the 1.5 V core supply simplifies power-tree design in fanless 1U appliances where the BGA's exposed die pad keeps junction temperature manageable.
Được đề xuất
Industrial Control Planes and Protocol Bridges
The 0 to +105 C industrial temperature grade makes the MPC8272VRTIEA viable for factory-floor control planes and protocol-bridge applications (e.g. EtherCAT / PROFINET to Ethernet/IP). The 64-bit memory bus ingests large process data sets, while the CPM multi-channel HDLC and Ethernet engines provide deterministic, low-jitter fieldbus connectivity. The integrated PCI/USB simplify uplink to SCADA or HMI PCs, and the SEC engine secures Modbus-over-TLS traffic. Designers can reuse the same hardware across plants by swapping firmware only.
Được đề xuất
Network-Attached Storage (NAS) Controllers
SMB-class NAS devices benefit from the MPC8272VRTIEA's PCI bus for RAID controller cards and its USB 1.1 ports for external backup targets. The SEC engine accelerates AES-XTS for encrypted volumes without measurable throughput loss, and the CPM's multi-channel Ethernet implements 802.3ad link aggregation. Pairing the device with SATA/PATA controllers over PCI yields a NAS head unit scalable to tens of terabytes; firmware is typically built on top of NXP's U-Boot plus an embedded Linux BSP.
Được đề xuất
Wireless Backhaul and LTE Small-Cell Baseband
Small-cell baseband cards run the MPC8272VRTIEA in a PCIe-crate chassis; its 32-bit PCI bus carries Ethernet fronthaul to the radio, while the SEC engine secures SCTP backhaul links. The CPM's FlexCAN and UTOPIA interfaces connect to legacy BTS peripherals, easing upgrade paths in hybrid 2G/3G/4G networks. The BGA's 27 mm footprint integrates neatly into compact small-cell PCBs, and the same PowerQUICC II toolchain supports firmware reuse across a wide frequency range.

Ghi chú thiết kế
Estimated: the 516-FPBGA exposes a large central die-pad block which must be soldered to a continuous copper land with thermal via array (typically 49-to-100 vias on a 1.2 mm pitch). With theta_JA in the 15-20 C/W range and junction temperature not to exceed 105 C, sustained total power dissipation of 5 to 8 W is realistic in still-air environments without forced airflow. Reduce core clock to 333 MHz (drop in MPC8272VRPIEA) to gain thermal headroom in fanless housings.
Estimated: the 64-bit external memory bus at 133 MHz plus 32-bit PCI at 66 MHz mandates a 6-layer PCB stack-up with continuous ground plane on layer 2, dedicated 3.3 V and 1.5 V power planes on layers 3 and 4, and impedance-controlled signal traces on the top/bottom layers (50 ohm single-ended, 90 ohm differential for USB). Reuse the NXP PowerQUICC II development kit stack-up as the baseline to avoid timing violations on the 60x bus.
Do not assume PowerQUICC II Linux BSPs from older MPC8245 boards boot cleanly on the MPC8272 - the SEC engine probe sequence differs and may hang at 'No crypto engine detected' messages. Verify boot ROM contents and U-Boot FDT entries explicitly reference the MPC8272 DIE ID. Also confirm JTAG TCK pin has a 1 kohm pull-down in production boards; leaving it floating can prevent boundary-scan attach after reflow.
Estimated: at 400 MHz the MPC8272VRTIEA draws up to 3 A on the 1.5 V core rail and 0.5 A on the 3.3 V I/O rail, requiring a switching regulator with at least 4 A peak capability (e.g. MIC22810 or TPS5430) and bulk decoupling of 220 uF low-ESR polymer plus 22 uF ceramic per rail. NXP recommends sequencing core voltage before I/O voltage by at least 10 ms to prevent uncontrolled bus contention.
