Product Introduction

Overview

The Texas Instruments MSP430G2444IRHA40R is a member of the MSP430G2x44 family of ultra-low-power microcontrollers. This device is designed to optimize power consumption, making it ideal for battery-powered and portable measurement applications. The MSP430G2444 features a 16-bit RISC CPU with 16-bit registers and constant generators, contributing to maximum code efficiency. It also includes a range of peripherals such as timers, a universal serial communication interface (USCI), and a 10-bit analog-to-digital converter (ADC) with integrated reference and data transfer controller.

  • 16-bit RISC CPU with 16-bit registers and constant generators.
  • 10-bit analog-to-digital converter (ADC) with internal reference, sample-and-hold, autoscan, and data transfer controller.
  • Brownout detector and ultra-fast wakeup from standby mode in less than 1 µs.
  • Serial onboard programming, no external programming voltage needed, and programmable code protection by security fuse.
  • Bootstrap loader (BSL) and on-chip emulation module.
  • Universal serial communication interface (USCI) supporting UART, LIN, IrDA, SPI, and I2C.
  • 16-bit timers (Timer_A and Timer_B) with three capture/compare registers each.
  • General-purpose digital I/O pins with pullup/down resistors.

Applications

  • Sensor systems that capture analog signals, convert them to digital values, and process the data for display or transmission to a host system.
  • Stand-alone radio-frequency (RF) sensor front ends.
