24 MHz MCU with 16KB FRAM, 2KB SRAM, comparator, 12-bit ADC, UART/SPI/I2C, timer

MSP430FR215x and MSP430FR235x microcontrollers (MCUs) are part of the

MSP430™ MCU value line portfolio of ultra-low-power low-cost

devices for sensing and measurement applications. MSP430FR235x MCUs integrate four configurable

signal-chain modules called smart analog combos, each of which can be used as a 12-bit DAC or a

configurable programmable-gain Op-Amp to meet the specific needs of a system while reducing the BOM

and PCB size. The device also includes a 12-bit SAR ADC and two comparators. The MSP430FR215x and

MSP430FR235x MCUs all support an extended temperature range from –40° up to 105°C, so higher

temperature industrial applications can benefit from the devices’ FRAM data-logging capabilities.

The extended temperature range allows developers to meet requirements of applications such as smoke

detectors, sensor transmitters, and circuit breakers.

The MSP430FR215x and MSP430FR235x 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) allows the device to wake up from low-power modes to active mode

typically in less than 10 µs.

The MSP430 ultra-low-power (ULP) FRAM microcontroller platform combines uniquely

embedded FRAM and a holistic ultra-low-power system architecture, allowing system designers to

increase performance while lowering energy consumption. FRAM technology combines the low-energy

fast writes, flexibility, and endurance of RAM with the nonvolatile behavior of flash.

MSP430FR215x and MSP430FR235x 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-EXP430FR2355

LaunchPad™ development kit and the MSP-TS430PT48 48-pin target development board.

TI also 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™ support forums.
