The STMPE1600 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 IC is often used in mobile multimedia platforms to solve the problems of the limited amount of GPIOs typically available on the digital engine.
I/O expanders provide a simple solution when additional I/O are needed for several interface functions such as sensors, pushbuttons, LEDs, fans, etc.
The STMPE1600 offers great flexibility as each I/O can be configured as input or output. The device has been designed with very low quiescent current and includes a wakeup feature for each I/O, to optimize the power consumption of the device.Key Features
