Description

The STMPE2401 is a GPIO (General Purpose

Input / output) port expander able to interface a

Main Digital ASIC via the two-line bidirectional

bus (I2C); separate GPIO Expander IC is often

used in Mobile-Multimedia platforms to solve the

problems of the limited amounts of GPIOs usually

available on the Digital Engine.

The STMPE2401 offers great flexibility as each

I/Os is configurable as input, output or specific

functions; it's able to scan a keyboard, also

provides PWM outputs for brightness control in

backlight, rotator decoder interface and GPIO.

This device has been designed very low

quiescent current, and is including a wake up

feature for each I/O, to optimize the power

consumption of the IC.

Potential application of the STMPE2401 includes

portable media player, game console, mobile

phone, smart phone
