MPC8247ZQMIBA

Overview

The MPC8247ZQMIBA is a microprocessor from the PowerQUICC II family, manufactured by NXP Semiconductors. It features a single-core PowerPC G2_LE architecture with a 32-bit data bus and operates at a maximum clock frequency of 266 MHz. The device is housed in a 516-pin PBGA package measuring 27x27 mm. It supports an operating voltage range of 1.425 V to 2.25 V and I/O voltages between 3.135 V and 3.465 V. Integrated memory includes 16 kB L1 instruction cache, 16 kB L1 data cache, and 4 kB or 16 kB data RAM. The processor supports external DRAM, SRAM, and SDRAM storage types.

Feature Summary

• Integrates a RISC-based Communications Processor Module (CPM) to offload low-level peripheral communications tasks, allowing the main core to manage high-level processing.
• Supports dual Fast Ethernet MACs, ATM, HDLC, PCI interface, and USB host/device interfaces for versatile connectivity.
• Includes hardware security engines supporting DES, 3DES, MD-5, SHA-1, AES, and ARC-4 encryption algorithms.

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance as some variants may not meet current standards. Check moisture sensitivity level (MSL 3) handling requirements during assembly. Validate pinout compatibility with existing PCB layouts before integration.

Selection Notes

Select this processor for applications requiring integrated hardware security and high on-chip integration. Consider the dual-core architecture for balanced processing loads. Ensure support for required protocols like ATM and HDLC. Evaluate power consumption needs against the 0.8 W specification at 266 MHz.

Part Context

Part of the MPC8272 PowerQUICC II family, which includes MPC8247, MPC8248, MPC8271, and MPC8272 processors. Designed for cost-sensitive networking and communications applications. Offers low-power operation and small-footprint packaging to reduce board space.

Replacement Considerations

No verified public substitute part numbers are available. The component is listed as End of Life (EOL). Designers should consult official documentation for potential obsolescence management strategies or alternative families within the PowerQUICC series.
