Microprocessors Procurement Notes

Verify the specific suffix VR80D4 against official datasheets to confirm package type and temperature range. Confirm component status as discontinued or not for new designs before procurement planning. Ensure compatibility with existing board layouts for the 357-pin BGA footprint.

Microprocessors Selection Notes

Select this model when high-speed Ethernet and ATM support are required alongside a robust communications processor module. Consider the 4K/4K cache configuration if code size is limited compared to the 16K/8K variants. Verify that the 80 MHz clock speed meets system timing requirements without exceeding bus constraints.

Microprocessors Part Context

This component belongs to the MPC860 PowerQUICC family, designed for integrated communications and networking applications. It builds upon the MC68360 QUICC architecture with enhanced memory controllers and additional I2C capabilities. The family targets cost-effective solutions for embedded network infrastructure.
