Procurement Notes

Verify component status before procurement as this part may be marked Not Recommended for New Designs. Confirm package availability matches design requirements, specifically the 28-pin QFN form factor. Ensure development tools support the C2 interface for programming and debugging. Check for end-of-life notifications or last-time-buy notices from the manufacturer to mitigate supply chain risks for long-term production.

Selection Notes

Select this component when a standalone 8-bit MCU with integrated high-resolution analog peripherals is required. It is suitable for designs needing direct ADC/DAC functionality without external converters. Consider the 28-pin QFN package constraints regarding PCB footprint and thermal dissipation. Evaluate power consumption profiles against application requirements, noting typical operating currents at various clock speeds.

Part Context

This device belongs to the C8051F35x series of mixed-signal microcontrollers. The family shares common specifications such as the 8051 core, memory architecture, and peripheral sets. Variations within the series typically involve differences in ADC resolution or specific pin configurations.
