STMPE801 - Hardware Interface guide

Introduction
STMPE801 is an eight-bit port expander that can be interfaced to the main digital ASIC or
processor via the two-line bidirectional I2C bus. The digital engines in mobile multimedia
platforms usually come with a limited number of I/Os. The port expander ICs can be used to
increase the number of I/Os or control signals in such applications.
STMPE801 can be used in advanced digital platforms such as:
● Portable media players
