MPC8260AZUPJDB

Overview

The MPC8260AZUPJDB is a PowerQUICC II integrated communications processor featuring a dual-issue G2 core and a RISC-based Communications Processor Module (CPM). It supports CPU frequencies up to 300 MHz with separate PLLs for the core and CPM. The device includes a 64-bit 60x bus, a 32-bit local bus, and a twelve-bank memory controller. Key peripherals include three Fast Communications Controllers (FCCs), four Serial Communications Controllers (SCCs), two Serial Management Controllers (SMCs), SPI, I2C, and eight TDM interfaces.

Feature Summary

• Dual-core architecture combining a PowerPC G2 integer core with a RISC-based Communications Processor Module for protocol offloading.
• Integrated high-speed serial communication controllers supporting Ethernet, ATM, HDLC, UART, and TDM protocols.
• Flexible memory subsystem with a twelve-bank controller supporting SRAM, SDRAM, DRAM, and Flash.
• Independent clocking capabilities allowing the G2 core and CPM to operate at different frequencies.

Applications

• Networking equipment such as routers and switches
• Wireless access points and residential gateways
• Industrial control systems
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'ZUPJDB' against official NXP documentation to confirm package type, temperature range, and revision level. Ensure compatibility with existing board designs regarding voltage levels and pin assignments. Confirm current availability status as older MPC82xx series components may be subject to discontinuation notices.

Selection Notes

Select this component for applications requiring high-performance embedded processing combined with extensive hardware-based communication protocol support. The dual-core design allows for efficient separation of network stack processing and application logic. Consider thermal management requirements given the power dissipation characteristics at higher clock speeds.

Part Context

This part belongs to the MPC826xA family, which includes the MPC8260, MPC8255, MPC8264, MPC8265, and MPC8266. These devices are based on the Power Architecture and are designed for cost-sensitive networking and communications applications. The MPC8260 serves as a baseline within this family, offering essential communication interfaces without the PCI bridge found in superset models like the MPC8265.

Replacement Considerations

Direct replacements within the same footprint and functionality include other members of the MPC826xA family such as the MPC8264 or MPC8266, provided the additional features (like PCI bridges) are compatible with the system design. Verify pinout and register compatibility before substitution.
