MPC8248VRPIEA

Overview

The MPC8248VRPIEA is a member of the PowerQUICC II family, fabricated on a .13µm (HiP7) process. It integrates a 32-bit G2_LE core with MMUs and 16 KB instruction/data caches, alongside a modified Communications Processor Module (CPM). Key features include an integrated Security Engine (SEC), USB 2.0 controller, PCI bridge, and dual Fast Ethernet MACs. The device operates at frequencies up to 400 MHz, utilizing separate 1.5 V logic and 3.3 V I/O supplies within a 516-pin lead-free PBGA package.

Feature Summary

• Integrated hardware security engine supporting DES, 3DES, MD-5, SHA-1, AES, PKEU, RNG, and RC-4 algorithms
• Dual processing architecture combining a Power Architecture core with a RISC-based Communications Processor Module
• Support for USB 2.0 full/low rate compatible host and slave modes
• PCI Specification revision 2.2-compliant bridge supporting frequencies up to 66 MHz

Applications

• Small and medium enterprise routers
• Virtual private network (VPN) and firewall routers
• Wireless access points
• Residential gateways and xDSL equipment

Procurement Notes

Verify component authenticity through authorized NXP channels or certified distributors. Confirm the specific ordering suffix VRPIEA matches the required lead-free package variant. Review the latest datasheet revision for any updates to electrical characteristics or pin configurations prior to finalizing procurement orders.

Selection Notes

Select this processor for applications requiring high integration of communications peripherals and hardware encryption. Ensure system design accommodates the separate 1.5 V and 3.3 V power domains. Verify that the 516-pin PBGA footprint aligns with available PCB layout resources and thermal management capabilities.

Part Context

This component belongs to the PowerQUICC II family, which also includes the MPC8272, MPC8271, and MPC8247. These devices share a common architectural foundation but differ in peripheral availability, such as the presence of the Security Engine or ATM support. The MPC8248 specifically targets cost-sensitive networking applications requiring robust security features.

Replacement Considerations

Direct replacements within the same family include the MPC8272, MPC8271, and MPC8247. Note that the MPC8272 offers additional ATM support not present in the MPC8248. Cross-referencing specific peripheral requirements against the functionality table in the MPC8272EC datasheet is essential before substitution.
