Description

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 the digital engine.

The STMPE1601 offers great flexibility, as each

I/O can be configured as input, output or specific

functions. The device is able to scan a keyboard,

also provides PWM outputs for brightness control

in backlight, and GPIO. This device has been

designed to include very low quiescent current,

and a wake-up feature for each I/O, to optimize

the power consumption of the IC.

Potential applications of the STMPE1601 include

portable media players, game consoles, mobile

and smart phones.
