The STMPE811QTR is a GPIO (general purpose input/output) port expander able to interface a main digital ASIC via the two-line bidirectional bus (I2C). A separate GPIO expander is often used in mobile multimedia platforms to solve the problems of the limited amount of GPIOs typically available on the digital engine.
The STMPE811QTR offers great flexibility, as each I/O can be configured as input, output, or specific functions. The device has been designed with a very low quiescent current and includes a wakeup feature for each I/O, to optimize the power consumption of the device.
A 4-wire touchscreen controller is built into the STMPE811QTR The touchscreen controller is enhanced with a movement tracking algorithm (to avoid excessive data), a 128 x 32-bit buffer, and a programmable active window feature.
