STM8TL52/L53 is the most advanced solution of ST’s STM8T capacitive proximity and touch-key controller family.
It offers up to 300 channels using the ProxSense™ charge-transfer capacitive acquisition principle.
The hardware peripheral combines advanced analog and digital processing to measure the electrode capacitance with no CPU load.
The fast projected capacitive acquisition minimizes the use of external components for a robust multiplexing of channels using a matrix of up to 15 Tx and 20 Rx.
