What the MSP430FR2310 does
The MSP430FR231x are mixed-signal microcontrollers featuring embedded nonvolatile FRAM, a 16-bit RISC CPU, and a configurable low-leakage transimpedance amplifier. These devices operate on a wide supply voltage range from 1.8 V to 3.6 V and consume only 0.71 µA in standby mode with a 32 kHz crystal. The family includes the MSP430FR2310 and MSP430FR2311, available in 16-pin and 20-pin TSSOP or VQFN packages. They integrate an 8-channel 10-bit ADC, a 16-bit DAC, and multiple timers. Typically used in smoke detectors, power monitoring systems, and portable health and fitness accessories, these MCUs offer extended battery life through extensive low-power modes and radiation-resistant architecture.
