(1) The MSP430F461x1 devices are identical to the MSP430F461x devices, with the exception that the ADC12 module is not implemented.

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.
