STMPE2401 - Port expander
PWM controller

Introduction
STMPE2401 is the first in the family of ST port-expander logic products. The principle of a
basic expander logic is to provide additional I/Os that can be used by the host processor to
implement additional features such as increasing the number of control signals and mixed
signal lines, or controlling more number of peripherals.
In addition to the above mentione
