MPC8248VRTIEA - PowerQUICC II 400MHz MPU | NXP 516-PBGA
MPN： MPC8248VRTIEA ⚠ 最後購買機會MPC8248VRTIEA 概覽
A PowerQUICC II communications processor is a type of embedded microprocessor that integrates a CPU core with dedicated networking and cryptographic peripherals, allowing networking equipment such as routers, switches, and DSLAMs to handle packet processing and encryption offload without companion ASICs. It belongs to the broader embedded microprocessor family, itself a sub-category of integrated circuits; the PowerQUICC lineage traces back to the Freescale MPC8xx PowerQUICC and PowerQUICC III successors, and represents a well-known architectural choice for telecom/datacom OEMs.
Key features of this part include a single 32-bit PowerPC G2_LE core running at 400MHz, hardware PCI interface, USB controller, dual 10/100 Ethernet via CPM, and an integrated SEC engine for DES/3DES/AES acceleration. The part is fabricated in a 0.13um HiP7 process and supports 60x bus up to 133MHz, plus DDR memory controller, dual UART, I2C, and SPI channels. The 516-PBGA footprint remains identical across the MPC8247/MPC8248/MPC8271/MPC8272 variants, enabling straightforward board reuse when scaling design requirements.
Architecturally, the MPC8248VRTIEA uses the G2_LE core (low-power variant of the classic G2) which incorporates a hardware MMU, separate instruction and data caches, and supports power-management modes that allow dynamic frequency and voltage scaling. The CPM operates semi-independently from the core via dedicated DMA, offloading table-walks, HDLC framing, and ATM SAR work from the CPU. The SEC block provides hardware-accelerated crypto, and the PCI/USB blocks share the same 60x local bus for register access.
Typical applications include entry-level to mid-range routers and switches, integrated access devices, DSLAM line cards, industrial control gateways, and secure networking appliances that need on-chip encryption. The wide peripheral integration reduces BOM cost and PCB area compared to designs using a discrete MPU plus companion communication controller.
When designing with the MPC8248VRTIEA, ensure the 1.5V core rail is generated by a low-noise LDO or buck converter with at least 1.5A capability to absorb peak current draw during CPM bursts. Use the manufacturer's reference schematics as a starting point for DDR memory routing and impedance matching. This part is now in NXP's discontinuance and replacement program, so check NXP's product change notice for last-time-buy and recommended successor information before starting new designs.

典型應用
MPC8248VRTIEA 適用於 6 應用s: Enterprise Router and Switch Control Plane, DSLAM Line Card Processor, Integrated Access Device (IAD) Gateway, Industrial Networking Gateway, Secure Networking Appliance, Legacy Telecom Datacom Equipment.
Enterprise Router and Switch Control Plane
The MPC8248VRTIEA integrates a 400MHz PowerPC G2_LE core with a CPM (Communications Processor Module) that can offload HDLC and ATM SAR tasks, plus dual 10/100 Ethernet MACs and a hardware SEC engine for IPsec. Because all of these blocks sit on a single die in a 27mm 516-PBGA, the part can serve as the main control-plane processor in entry-level to mid-range branch-office routers. The CPM DMA burst profile during table-walks can draw transient currents well above the average datasheet number, so a 1.5V buck regulator with at least 1.5A capability is recommended.
推薦
DSLAM Line Card Processor
The PowerQUICC II CPM provides dedicated HDLC and ATM SAR channels that match DSLAM line-card requirements, and the SEC engine accelerates IPsec for secured subscriber sessions. Operating temperature of 0 to 105C (industrial extended) makes the part suitable for central-office deployments where ambient inside the chassis can run hot. Because the device shares its package with the entire MPC8247/MPC8248/MPC8271/MPC8272 family, OEMs can up-range or down-range line cards without re-spinning the PCB layout.
推薦
Integrated Access Device (IAD) Gateway
With on-chip PCI, USB, dual Ethernet, and a 32-bit PowerPC core, the MPC8248VRTIEA can replace the classic two-chip solution (CPU plus a companion communication controller) inside small business IAD gateways. The integrated SEC engine handles VPN encryption, eliminating the need for a discrete crypto chip and shrinking PCB area. DDR memory controller support simplifies layout because no external memory bridge is required for the main system RAM.
推薦
Industrial Networking Gateway
The 0 to 105C operating range and the legacy industrial connectivity (I2C, SPI, dual UART) make the MPC8248VRTIEA a fit for industrial Ethernet-to-serial protocol gateways. The CPM can handle deterministic packet scheduling for protocols like PROFINET or EtherNet/IP bridging, while the G2_LE core runs the main application stack. Engineers planning new designs in 2026 should weigh the part's last-time-buy status against using a NXP Layerscape successor.
推薦
Secure Networking Appliance
The on-chip SEC block accelerates DES, 3DES, AES, and public-key algorithms used in IPsec VPN and SSL termination appliances. Combined with the dual 10/100 Ethernet and PCI/USB host capability, the MPC8248VRTIEA can form the heart of a small-office security appliance without companion crypto chips. Estimated worst-case dissipation around 2.5W means the 27mm PBGA still requires thermal vias but not an external heatsink in most chassis designs.
推薦
Legacy Telecom Datacom Equipment
Many legacy telecom and datacom products in service with carriers, utilities, and industrial customers were built around the PowerQUICC II family, and the MPC8248VRTIEA is a known control-plane choice for those designs. Because the part is in last-time-buy, OEMs running long-life service contracts need to secure inventory or migrate to a same-family drop-in. The 516-PBGA 27mm footprint allows reuse of existing PCB assemblies when moving between MPC8247, MPC8248, MPC8271, and MPC8272.

主要差異化特點
- Highest speed (400MHz) variant of the MPC8248 ordering scheme with full CPM/SEC integration (對比MPC8248CZQTIEA)
- Industrial-extended 0 to 105C operating temperature window (對比MPC8248VRMIBA)
- Full peripheral set within the same 27mm 516-PBGA footprint (對比MPC8247VRTIEA)
設計說明
Estimated: at 400MHz and full CPM activity, the 1.5V core rail can pull transient currents above the average datasheet number during HDLC/ATM SAR bursts. Use a buck regulator rated for at least 1.5A continuous on the 1.5V rail with low-ESR bulk ceramic decoupling placed as close to the BGA balls as practical. The 3.3V I/O rail is less demanding but should still be sequenced after the 1.5V core ramp per the PowerQUICC II reference design.
The 27mm 516-PBGA package has a thermal resistance that requires thermal vias in the PCB land pattern. Without a continuous via field under the die, the part can exceed its 105C operating case temperature during sustained CPM activity. In chassis with restricted airflow, derate the maximum ambient to keep junction temperature inside the spec. Most PowerQUICC II designs use a 4-layer or 6-layer stackup with thermal via arrays under the package.
Use the NXP reference schematic as a starting point for DDR memory routing and impedance control. Match trace lengths for the DDR clock, address, and command groups to within the tolerances listed in the hardware specifications. Keep the BGA decoupling capacitors on the top side of the board within 1mm of their assigned balls to control the high-frequency current loop area.
Do not design a new greenfield product around this part in 2026 because NXP has it listed in discontinuance and replacement. Engineers servicing long-life telecom equipment should source authorized inventory or plan a migration to a same-family drop-in or to the NXP Layerscape / QorIQ families. Always read the product change notice PDF before committing to a board revision, since the recommended successor can shift over time.
