This feature is enabled by the inclusion of a Digital Direct Output (DDO) mode that, in addition to conventional I2C and SPI host communication interfaces, allows the ATB252 to be directly configured from an EEPROM to provide a standalone solution.


The ATB252 implements Aito’s SEP technology, that allows touch buttons to be implemented on metal and other surfaces, and supports up to 6 piezo touch key inputs in combination with up to 11 LED indicators and a buzzer output.
