(1)The transimpedance amplifier was originally given an abbreviation of TRI in descriptive text, pin names, and register names. The abbreviation has changed to TIA in all descriptive text, but pin names and register names still use TRI.
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.
