Selecting the right microcontroller (MCU) increases the ease of passing the certification and helps bring a product faster-to-market. With this certification, manufacturers can now easily design household appliances that are IEC/EN-ready with Atmel capacitive touch controllers for buttons, sliders and wheels.      

The new capacitive touch controllers include the Atmel AT42QT1244, AT42QT1245, AT42QT2640 and AT42QT1481. All devices are IEC/EN 60730 Class B certified and include Failure Mode Effect Analysis (FMEA) support to monitor self-tests to ensure the system is running properly. In addition, all the new touch controllers include Atmel’s patented Adjacent Key Suppression (AKS) mode which provides more precise discrimination between closely spaced keys; moisture tolerance with Atmel’s patented QMatrix technology for extreme environments; and supports high button counts through 24-, 48- or 64- acquisition channels. All Atmel touch controllers are ready to use with no MCU programming and configurations are completed through UART, SPI or I2C interfaces.

Pricing for the Atmel AT42QT1481, AT42QT1244, AT42QT1245, AT42QT2640 start at $2.48 for 1,000-piece quantities. Production quantities for the Atmel AT42QT1481 are available now, while production quantities for the AT42QT1244, AT42QT1245, AT42QT2640 are available in Q4 FY2011.
