MPC8248CVRMIBA - PowerQUICC II 266MHz MPU, 516-PBGA | NXP
MPN: MPC8248CVRMIBA ⚠ آخرین فرصت خریدMPC8248CVRMIBA نمای کلی
An integrated communications processor (also called PowerQUICC) is a system-on-chip that combines a general-purpose microprocessor core with dedicated communications peripherals. The CPM offloads serial protocol processing from the main core, freeing CPU cycles for application logic. PowerQUICC II sits within the broader taxonomy of embedded processors -> microprocessors -> communications processors -> networking SoCs, and serves as a member of NXP/Freescale's long-running PowerQUICC family targeting routers, switches, and access equipment.
Key features of the MPC8248CVRMIBA include 266 MHz core frequency, integrated SEC 2.0 with Talitos for hardware-accelerated cryptography, dual 10/100 Ethernet interfaces through the CPM, USB 1.1 host/device support, PCI 2.2 interface, and an industrial -40C to +105C temperature range. The integrated MMU and 32-bit Power Architecture core support both legacy PowerPC and standard networking operating systems.
This part is fabricated on a 0.13 µm HiP7 process and combines silicon semiconductor die with a halogen-free organic substrate. The PowerQUICC II architecture pairs the G2_LE core with the CPM block, which independently handles up to three Fast Communications Controllers (FCCs), multiple SCCs, and ATM/POS-PHY support depending on silicon revision.
Typical applications include small/medium enterprise routers, DSLAM line cards, wireless base station controllers, industrial control gateways, and secure VPN appliances. The SEC/Talitos block accelerates DES/3DES/AES/SHA, allowing IPsec VPN line-rate throughput without burdening the host core.
When designing with this device, allocate adequate PCB area for the 27x27 mm 516-ball PBGA footprint - it requires a multilayer board with microvia technology for inner-row balls. Plan thermal dissipation carefully; at typical 0.8 W power dissipation at 266 MHz, the part stays within junction limits with standard airflow, but sealed enclosures may require thermal modeling.

کاربردهای معمول
MPC8248CVRMIBA مناسب است برای 6 کاربردs: Small/Medium Enterprise Router, DSLAM Line Card Controller, Wireless Base Station Controller, Secure VPN Appliance, Industrial Control Gateway, Network Attached Storage Controller.
Small/Medium Enterprise Router
The MPC8248CVRMIBA fits SME router designs where its integrated CPM offloads packet processing from the 266 MHz G2_LE core, freeing CPU cycles for routing protocols. Its dual 10/100 Ethernet ports handle LAN/WAN interfaces without external MACs, while the SEC 2.0/Talitos block accelerates IPsec VPN encryption at wire speed. Compared to using a discrete host CPU plus network processor, this single-chip solution reduces BOM cost and PCB area while drawing just 0.8 W typical power. The industrial -40 to +105C temperature range supports deployment in uncontrolled environments like wiring closets.
پیشنهادی
DSLAM Line Card Controller
In DSLAM line cards, the MPC8248CVRMIBA manages multiple ADSL/VDSL channels through its CPM's multi-channel serial controllers while the host core handles ATM segmentation/reassembly and traffic management. The PCI 2.2 interface links the processor to upstream switch fabric ASICs, and USB 1.1 supports local maintenance/diagnostic access. At 266 MHz with 505.4 MIPS, the part comfortably handles control-plane processing for 24-48 port line cards without bottlenecking. Its 516-PBGA package suits the high-density line card layouts typical of central office equipment.
پیشنهادی
Wireless Base Station Controller
The MPC8248CVRMIBA serves as the control processor in 2G/3G base station controllers where its PowerPC architecture and CPM integrate cleanly with telecom software stacks. Industrial -40 to +105C operation supports outdoor cabinet deployment, while the SEC engine secures backhaul links. The integrated USB and Ethernet peripherals simplify baseband module interconnection. Pin-compatible migration to faster MPC8272 variants enables field upgrades to higher call-capacity base stations without PCB redesign, preserving NRE investment across product generations.
پیشنهادی
Secure VPN Appliance
The MPC8248CVRMIBA is well-suited for branch-office VPN appliances because its Talitos hardware crypto accelerator performs AES-256/SHA-256 IPsec transforms at multi-gigabit rates independent of the host CPU. The 266 MHz G2_LE core runs the IKE key management and routing daemons while Talitos handles data-plane encryption. This partitioning allows sustained VPN throughput that software-only crypto cannot match at this MIPS class. The PCI interface accommodates optional hardware security modules or crypto accelerator cards for higher-tier appliances.
پیشنهادی
Industrial Control Gateway
Factory floor protocol gateways leverage the MPC8248CVRMIBA's industrial temperature range and rich peripheral mix to bridge Modbus/Profibus serial protocols to Ethernet/IP networks. The CPM's multiple SCCs handle several serial slaves simultaneously while the host core runs gateway logic and web management interfaces. The integrated USB supports local configuration/diagnostics, and PCI allows expansion for additional fieldbus cards. At 0.8 W typical dissipation, the part fits sealed enclosures without active cooling in most factory environments.
پیشنهادی
Network Attached Storage Controller
Entry-level NAS controllers use the MPC8248CVRMIBA as the main processor where its PowerPC core runs embedded Linux with Samba/NFS, and the PCI interface accommodates SATA or SCSI host bus adapters. The CPM's Ethernet ports serve 10/100 network connectivity while USB supports external backup drives. Industrial temperature operation enables deployment in small-business server rooms without climate control. Pin-compatible MPC8272 upgrades support higher-tier NAS products with gigabit Ethernet migration paths.

یادداشت‌های طراحی
The 516-PBGA package at 1.0 mm ball pitch requires a multilayer PCB (typically 6+ layers) with microvia or via-in-pad technology to route inner-row signals. Per NXP design guidelines, allocate at least 4 routing layers and 2 ground/power planes; missing microvias will result in incomplete electrical connections that fail factory test or in-field. Plan escape routing before final stackup selection.
Estimated: at 0.8 W typical dissipation in a still-air environment, junction temperature rise depends heavily on PCB copper area around the BGA. Use NXP's thermal model document to validate your specific board; for sealed enclosures without airflow, add a 1-2 mm gap thermal interface material pad to a metal chassis wall. Theta-JA values for the 516-PBGA are documented in the package mechanical drawing appendix.
Do not confuse the MPC8248CVRMIBA (industrial temp with Talitos) with the MPC8248VRMIBA (commercial temp). Same part number family, but operating-temperature differences cause field failures if substituted incorrectly. Verify the 'C' designator in the MPN suffix and cross-check against the ordering information table in the datasheet before committing to a BOM.
