Description

The STMPE1801 is a GPIO (general purpose

input/output) port expander capable of interfacing

a main digital ASIC via the two-line bidirectional

bus (I2C). A separate GPIO expander IC is often

used in mobile multimedia platforms to resolve

the problem of the limited number of GPIOs

typically available on digital engines.

The STMPE1801 offers high flexibility, as each

I/O can be configured as input, output, special

key, keypad matrix or dedicated key function. This

device is designed to include very low quiescent

current, and a wakeup feature for each I/O, to

optimize the power consumption of the device.

Potential applications for the STMPE1801 include

portable media players, game consoles, mobile

and smart phones.
