Description

The STMPE801 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 STMPE801 offers great flexibility as each

I/Os is configurable as input, output. This device

has been designed very low quiescent current,

and includes wake up feature for each I/O, to

optimize the power consumption of the IC.
