The ultra-low-power MSP430FR231x FRAM microcontroller (MCU) family consists of several devices that feature embedded nonvolatile FRAM and different sets of peripherals targeted for various sensing and measurement applications. The architecture, FRAM, and peripherals, combined with extensive low-power modes, are optimized to achieve extended battery life in portable and wireless sensing applications. FRAM is a new nonvolatile memory that combines the speed, flexibility, and endurance of SRAM with the stability and reliability of flash, all at lower total power consumption.
The MSP430FR231x FRAM MCU is the worlds first microcontroller with a configurable low-leakage current sense amplifier and features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) also allows the device to wake up from low-power modes to active mode typically in less than 10 µs. Additionally, developers can reduce PCB real estate by up to 75 percent with integrated analog, EEPROM, crystal, and MCU functionality in a 4-mm × 3.5-mm package. The feature set of this microcontroller is ideal for applications ranging from smoke detectors to portable health and fitness accessories.
(1)Operation voltage is restricted by SVS levels (see VSVSH- and VSVSH+ in Power Supply Sequencing).
(2)The transimpedance amplifier was originally given an abbreviation of TRI for use in descriptive text, pin names, and register names. The abbreviation has been changed to TIA in all descriptive text, but pin names and register names still use TRI.
