STMPE821 Overview
The STMPE821 is a GPIO (general purpose input/output) port expander able to interface a main digital ASIC via the two-line bidirectional bus (I2C). A separate GPIO expander is often used in mobile multimedia platforms to solve the problems of the limited amount of GPIOs typically available on the digital engine. The STMPE821 offers great flexibility, as each I/O can be configured as input, output or specific...
