Ultra-low-power MCUs offer extended battery life in portable measurement applications

Texas Instruments MSP430F21x2 16-Bit Ultra-Low-Power MCUs are part of the MSP430 family of microcontrollers. These MCUs have an architecture, coupled with five low-power modes, that is optimised to deliver extended battery life in portable measurement applications. The device highlights a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The DCO enables wake-up from low-power modes to active mode in less than 1µs. The device comes with two built-in 16-bit timers, a fast 10-bit A/D converter with integrated reference and a DTC. It also comprises a comparator, built-in communication capability using the universal serial communication interface, and up to 24 I/O pins. The devices feature gold bond wires, a temperature range of –55C to +105C and include an SnPb lead finish.
