description
The Texas Instruments MSP430 family of ultralow power microcontrollers consist of several devices featuring
different sets of peripherals targeted for various applications. The architecture, combined with five low power
modes is optimized to achieve extended battery life in portable measurement applications. The device features
a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that attribute to maximum code efficiency.
The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 6µs.
The MSP430FG43x series are microcontroller configurations with two 16-bit timers, a high performance 12-bit
A/D converter, dual 12-bit D/A converters, three configurable operational amplifiers, one universal
synchronous/asynchronous communication interface (USART), DMA, 48 I/O pins, and a liquid crystal display
(LCD) driver.
Typical applications for this device include analog and digital sensor systems, digital motor control, remote
controls, thermostats, digital timers, hand-held meters, etc.
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range
from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage
because very small parametric changes could cause the device not to meet its published specifications. These devices have limited
built-in ESD protection.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
