The Texas Instruments MSP430™ family of
ultra-low-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 device
features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to
maximum code efficiency. The calibrated digitally controlled oscillator (DCO) allows wake-up from
low-power modes to active mode in less than 1 µs.
The MSP430F261x and MSP430F241x series are microcontroller configurations with two
built-in 16-bit timers, a fast 12-bit ADC, a comparator, two 12-bit DACs, four USCI modules, DMA,
and up to 64 I/O pins. The MSP430F241x devices are identical to the MSP430F261x devices, with the
exception that the DAC12 and the DMA modules are not implemented.
The LQFP-64 package is also available as a nonmagnetic package for medical imaging
