Product Overview

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.
  • 8 GPIOs
  • 1.8 - 3.3V operating voltage
  • Integrated 4-wire touchscreen controller
  • Interrupt output pin
  • Wakeup feature on each I/O
  • SPI and I2C interface
  • Up to 2 devices sharing the same bus in I2C mode (1 address line)
  • 8-input 12-bit ADC
  • 128-depth buffer touchscreen controller
  • Touchscreen movement detection algorithm
