description
The Texas Instruments MSP430 family of ultralow-power microcontrollers consists 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 devices feature
a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code
efficiency. The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less
than 6 µs.
The MSP430x461x(1) series are microcontroller configurations with two 16-bit timers, a high-performance
12-bit A/D converter (MSP430x461x only), one universal serial communication interface (USCI), one universal
synchronous/asynchronous communication interface (USART), DMA, 80 I/O pins, and a liquid crystal display
(LCD) driver with regulated charge pump.
Typical applications for this device include portable medical applications and e-meter applications.
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.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.
