Procurement Notes

Verify the specific ordering suffix matches the required package type, as the C8051F36x family utilizes distinct packages for different model variants. Confirm that the selected variant aligns with the necessary analog peripheral availability, particularly regarding the ADC and DAC inclusion which varies across the series. Ensure compliance with RoHS standards and check for any end-of-life notices associated with this component family.

Selection Notes

Select the C8051F361-GQ when a 32-pin LQFP package is required alongside the full suite of analog peripherals found in the 'F360/1/2/6/7/8/9 variants. Consider the 100 MIPS peak performance and the integrated debug interface for rapid development cycles. Evaluate the 2.7–3.6 V operating range against system power constraints and verify that the 32 kB Flash capacity meets application storage needs.
