Touch Screen Controller ICs Minimize Demands on Host Processor ( 1 Jul 2008 )

STMicroelectronics' STMPE811 touch screen controller IC is afour-wire resistive touch screen controller featuring autonomousfunctionality to minimize demands on the host processor. Built-infeatures include an internal 12-bit ADC for high resolution as wellas 128x32-bit FIFO data buffers for smooth position tracking. Thereare also features for accurate position identification and awindow-masking function to support multiple sense windows.

Special low-power design features achieve active current below 1mA,idle current less than 1
