BS816A-1 Description
The BS81x is a series of 2~16 key touch key devices which can detect human body contact using external touch pads. The high level of device integration enable applications to be implemented with a minimum number of external ponents. The BS81x series devices are equipped with serial or parallel interfaces to allow easy munication with an external MCU for device setup and for touch pin monitoring purposes.
