Description

The STMPE2401TBR is a highly integrated mixed-signal IC from STMicroelectronics, designed to provide a comprehensive solution for input/output (I/O) port expansion and keypad matrix scanning in mobile and portable electronics. This versatile chip is well-suited for applications where additional I/Os are required, such as smartphones, tablets, and other compact devices where board space is at a premium.

Key Features

  • 24 GPIOs: The device offers 24 general-purpose input/output ports, which can be individually programmed to interface with digital signals, providing flexibility in design.
  • Keypad Interface: It includes a built-in keypad scanning interface capable of managing a matrix of up to 8x8 keys, allowing for the detection of multiple key presses simultaneously (ghost key recognition).
  • Enhanced Interrupt System: Each I/O can be configured with an interrupt generation feature, enabling the device to alert the host processor of any input changes, thus reducing processor load and power consumption.
  • Robust ESD Protection: The STMPE2401TBR is designed with high ESD protection, safeguarding the device from electrostatic discharges that are common in handheld devices.
  • Configurable Polarity and Edge Detection: The I/O ports support both level and edge detection with configurable polarity, giving designers control over input signal processing.
  • Low Power Consumption: Its power management capabilities include an advanced low-power mode, making it ideal for battery-operated devices.

Technical Specifications

  • Package: TQFP-32 (7x7 mm)
  • Supply Voltage: 2.3V to 3.6V, suitable for lithium-ion battery-powered applications.
  • Operating Temperature Range: -40°C to +85°C, ensuring reliable operation under extreme conditions.
  • Communication Interface: I2C and SMBus compatible, providing easy integration with most microcontrollers.

Applications

The STMPE2401TBR is ideal for a variety of applications, including but not limited to:

  • Portable media players
  • Mobile phones and smart devices
  • Personal digital assistants (PDAs)
  • Handheld gaming consoles
  • Industrial control systems

With its rich set of features and high level of integration, the STMPE2401TBR from STMicroelectronics is a powerful component for designers looking to expand the capabilities of their products without compromising on space or power efficiency.
