Procurement Notes
Verify the specific suffix BRHA1 against official Microchip documentation to confirm packaging details such as reel or cut tape specifications. Ensure the component meets the required environmental temperature ratings for the target application environment before procurement.
Selection Notes
Select this controller when designing home appliances that require IEC/UL 60730 Class B certification. It is suitable for systems where reducing bill-of-materials by removing external safety buttons is a priority. Confirm compatibility with the host MCU's I2C or SPI interface speeds and voltage levels.
Part Context
This part belongs to the ATMXT448 series of maXTouch controllers. The ATMXT448UD variant specifically targets the home appliance market with enhanced safety features. The CCUBRHA1 suffix indicates specific packaging and ordering parameters defined by Microchip Technology.
Replacement Considerations
Consult Microchip's official obsolescence notices and cross-reference tools for verified substitutes. Generic capacitive touch controllers may not provide the necessary IEC/UL 60730 Class B certification required for this specific application.
