Description

The STMPE811 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 STMPE811 offers great flexibility, as each I/O

can be configured as input, output or specific

functions. The device has been designed with

very low quiescent current and includes a wakeup

feature for each I/O, to optimize the power

consumption of the device.

A 4-wire touchscreen controller is built into the

STMPE811. The touchscreen controller is

enhanced with a movement tracking algorithm (to

avoid excessive data), a 128 x 32 bit buffer and

programmable active window feature.
