MPC8272ZQTIEA

Overview

The MPC8272ZQTIEA is a PowerQUICC II integrated communications processor featuring a 32-bit G2_LE core and a Communications Processor Module (CPM). It supports CPU frequencies from 266 MHz to 400 MHz with separate PLLs for the core and CPM. The device includes an integrated Security Engine (SEC) supporting DES, 3DES, MD-5, SHA-1, AES, PKEU, RNG, and RC-4 algorithms. Connectivity features dual Fast Ethernet MACs, USB 2.0, ATM support via UTOPIA II, and a PCI bridge up to 66 MHz. It utilizes a 516-pin PBGA package with lead spheres.

Feature Summary

• Communications Processor Module offloading peripheral tasks
• USB 2.0 host and slave mode support

Applications

• Small and medium enterprise routers
• Virtual private network equipment
• Wireless access points
• Industrial control systems

Procurement Notes

Verify component authenticity through authorized NXP channels. Confirm package type ZQ indicates lead spheres. Check RoHS compliance status. Ensure supply chain integrity for discontinued components.

Selection Notes

Evaluate thermal requirements against junction-to-ambient resistance values. Verify voltage levels match 1.5V core and 3.3V I/O specifications. Assess clock configuration needs for specific frequency ratios between core and bus.

Part Context

Part of the MPC8272 family including MPC8247, MPC8248, and MPC8271. Shares architecture but varies in security engine presence and ATM support. ZQ suffix denotes specific 516-pin PBGA packaging with lead spheres.

Replacement Considerations

Consult official documentation for direct substitutes within the PowerQUICC II family. Verify functional equivalence regarding security engine and interface availability.
