Microcontrollers Procurement Notes

Verify the specific suffix 'MFDE' against official NXP documentation to confirm package type and operating temperature range. Ensure compatibility with existing board layouts for the QFN-48 footprint. Check for moisture sensitivity levels and reflow soldering profiles required for surface-mount assembly. Confirm end-of-life status if sourcing from secondary markets.

Microcontrollers Selection Notes

Select this component when an 8-bit architecture with moderate Flash capacity and integrated analog peripherals is required. The wide operating temperature range suits harsh environments. Compare pin counts and peripheral sets against other S08AC variants to ensure sufficient I/O availability. Consider power consumption characteristics relative to the 40 MHz clock speed for battery-operated designs.

Microcontrollers Part Context

This part belongs to the Freescale (now NXP) S08AC family of 8-bit microcontrollers. These devices are designed for cost-sensitive applications needing reliable performance. The family shares common architectural features while varying in memory size and peripheral configurations. The MC9S08AC8 represents a specific configuration within this broader product line.

Microcontrollers Replacement Considerations

Check for direct substitutes within the MC9S08AC series with different memory sizes. Verify pin-to-pin compatibility with other QFN-48 packages in the S08 family. Consult official cross-reference guides for any updated part numbers replacing older Freescale designations.
