Description

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.
