STMPE1601 Datasheet (STMicroelectronics) - 16-bit enhanced port expander

STMPE1601, 16-bit enhanced port expander

The STMPE1601 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 number of GPIOs typically available on th
