(1) The MSP430F24x1 devices are identical to the MSP430F24x

devices, with the exception that the ADC12 module is not

implemented on the MSP430F24x1.

DESCRIPTION

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 MSP430F23x, MSP430F24x(1), and MSP430F2410 series are microcontroller configurations with two builtin

16-bit timers, a fast 12-bit A/D converter (not MSP430F24x1), a comparator, four (two in MSP430F23x)

universal serial communication interface (USCI) modules, and up to 48 I/O pins. The MSP430F24x1 devices are

identical to the MSP430F24x devices, with the exception that the ADC12 module is not implemented. The

MSP430F23x devices are identical to the MSP430F24x devices, with the exception that a reduced Timer_B, one

USCI module, and less RAM are integrated.

Typical applications include sensor systems, industrial control applications, and hand-held meters.
