• Portable instrumentation and measurement devices
• Battery-powered embedded systems utilizing low-power modes

Procurement Notes

Verify the specific suffix 'C-IS' corresponds to the required industrial temperature range (-40°C to +125°C) and SOIC-16 package. Confirm that the component is sourced as a valid part despite the manufacturer's Not Recommended for New Designs status. Ensure compatibility with existing design infrastructure before procurement.

Selection Notes

Select this component when a cost-effective 8-bit MCU with integrated analog peripherals is required. It is suitable for designs needing moderate Flash capacity and basic communication interfaces. Consider the AEC-Q100 qualification if automotive reliability standards are necessary. Evaluate power consumption requirements against the specified idle and stop mode currents.

Part Context

This part belongs to the C8051F85x/86x series, which provides a highly integrated solution for control applications. The family shares architectural similarities but varies in memory size and package options. The C8051F864 variant specifically offers the maximum Flash and RAM configuration within the 16-pin footprint constraints of this series.
