Procurement Notes
Verify the specific suffix 'GMR' indicates tape and reel packaging configuration. Confirm RoHS compliance status matches current regulatory requirements. Check for any product change notices regarding assembly or labeling updates. Ensure the component lifecycle status is reviewed against long-term supply needs. Validate pinout compatibility if replacing existing designs.
Selection Notes
Select this part when 8-bit performance with integrated capacitive sensing is required. Consider the 2.2V minimum supply voltage for battery-operated designs. Evaluate the 12-bit ADC resolution against signal processing needs. Compare pin count and package size constraints with alternative C8051F9xx variants. Assess the need for internal oscillator accuracy versus external crystal requirements.
Part Context
This component belongs to the C8051F9xx family of mixed-signal microcontrollers. It shares architectural similarities with other members like the C8051F930 but offers distinct peripheral configurations such as CapSense. The family emphasizes high integration and low power consumption for embedded applications.
Replacement Considerations
Check for direct substitutes within the C8051F9xx series with compatible pinouts. Verify functional equivalence of the CapSense module in alternative parts. Review datasheet errata for known issues affecting similar silicon revisions.
