The STMPE1600 is a 16-bit port expander with ultra-low power consumption
The STMPE1600 is a general-purpose input/output (GPIO) port expander designed to interface with a main digital ASIC via a two-line bidirectional I2C bus. It is commonly used in mobile multimedia platforms to address the limited number of GPIOs available on digital engines. The device features 16 GPIOs that default to inputs on power-up and includes a wakeup feature for each I/O to optimize power consumption.
