SO-16
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.
