STMPE2401 is a GPIO port expander that provides additional I/Os to the host processor to implement features such as increased number of inputs/outputs, expanding the number of control signals and mixed signal lines, controlling a greater number of peripherals.
The STMPE2401 is a GPIO port expander designed to interface with digital ASICs via a two-line bidirectional I2C bus. It provides 24 configurable I/Os and includes integrated intelligence for advanced features such as keypad scanning, PWM control, and rotator dial control. The device is optimized for low power consumption and is suitable for applications in mobile communications, game consoles, and embedded systems.
