STMPE811


4-Wire Resistive Touch Screen Controller with GPIOs


The STMPE811 is a 4-wire resistive touch screen controller with a GPIO (general purpose input/output) port expander able to interface a microcontroller or a main digital ASIC via I2C or SPI serial interface. The STMPE811 offers great flexibility, as each I/O can be configured as input, output or specific functions. The touch screen controller is enhanced with a movement tracking algorithm to avoid excessive data, 128 x 32 bit buffer and a programmable active window feature.
