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
