16 MHz ultra-low-power microcontroller extends battery life in portable measurement applications

This post sponsored by Texas Instruments.

The Texas Instruments MSP430 family of low-power microcontrollers consists of several devices that feature different sets of peripherals targeted for various applications. 

The architecture, combined with extensive low-power modes, is optimized to achieve extended battery life in portable measurement applications. MSP430 features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency.

The digitally controlled oscillator allows the device to wake up from low-power modes to active mode in less than 10 µs. The MSP430 CPU has a 16-bit RISC architecture that is highly transparent to the application. Almost all operations are performed as register operations in conjunction with seven addressing modes for source operand and four addressing modes for destination operand. The CPU is integrated with 16 registers that provide reduced instruction execution time. The register-to-register operation execution time is one cycle of the CPU clock. Peripherals are connected to the CPU using data, address, and control buses, and can be handled with all instructions. The MSP430 has one active mode and several software-selectable low-power modes of operation.
