16 MHz integrated analog microcontroller with 2 KB FRAM, OpAmp, TIA, comparator with DAC, 10-bit ADC

The MSP430FR231x FRAM microcontrollers (MCUs) are part of the MSP430™ MCU value line sensing family. The devices integrate a configurable

low-leakage transimpedance amplifier (TIA) and a general purpose operational amplifier. The MCUs

feature a powerful 16-bit RISC CPU, 16-bit registers, and a constant generator 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. The feature set of these MCUs

are well suited for applications ranging from smoke detectors to portable health and fitness

accessories.

The ultra-low-power MSP430FR231x 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 nonvolatile memory technology that combines the speed, flexibility, and

endurance of SRAM with the stability and reliability of flash at lower total power

consumption.

The MSP430FR231x MCUs are supported by an extensive hardware and software ecosystem

with reference designs and code examples to get your design started quickly. Development kits

include the MSP‑EXP430FR2311

LaunchPad™ development kit and the

MSP‑TS430PW20 20-pin target development

board. TI provides free MSP430Ware™ software, which is available as a component of

Code Composer

Studio™ IDE desktop and cloud versions within

TI Resource Explorer. The MSP430 MCUs are also

supported by extensive online collateral, training, and online support through the

E2E™ Community Forum.
