The STMPE811 is a four-wire resistive touch screen controller featuring autonomous functionality to minimize demands on the host processor. For embedded designers, this frees valuable CPU cycles to ease pressures on performance, power consumption and response times. Built-in features include an internal 12-bit ADC for high resolution as well as 128 x 32-bit FIFO data buffers for smooth position tracking. Special low-power design features achieve active current below 1mA, idle current less than 1 microampere, and an ultra-low-power 150nA hibernation mode.
