Description

The STMPE801QTR from STMicroelectronics is a highly integrated 8-bit General Purpose Input/Output (GPIO) expander with a rich feature set that enhances the capabilities of microcontroller-based systems. This compact and efficient component is designed to minimize the need for additional components, making it an ideal solution for expanding the number of GPIOs in a space-constrained application.

Key Features

  • Interface: The STMPE801QTR utilizes an I²C interface, allowing for easy integration into existing systems without the need for extensive rewiring or complex protocols.
  • 8 GPIO Ports: It provides eight GPIO ports that can be configured as either inputs or outputs, offering versatility for various applications.
  • Interrupt Functionality: The device features an interrupt output which can be configured to alert the host microcontroller of changes to the input pins, thereby reducing the need for constant polling and saving power.
  • Polymorphic Pin Configuration: Each GPIO can be individually set with different functionalities, such as high-impedance input, push-pull output, open-drain output, or pull-up/pull-down configuration.
  • Power Management: The STMPE801QTR supports power-saving modes, making it suitable for battery-operated devices by reducing power consumption when the GPIOs are not in use.

Applications

The versatility of the STMPE801QTR makes it well-suited for a wide range of applications, including:

  • Mobile devices
  • Personal electronics
  • Industrial controls
  • Home automation systems
