3 Description

MSP430FR2000 and MSP430FR21xx devices are part of the MSP430™ microcontroller (MCU) value line

sensing portfolio. This ultra-low-power, low-cost MCU family offers memory sizes from 0.5KB to 4KB of

FRAM unified memory with several package options including a small 3-mm×3-mm VQFN package. The

architecture, FRAM, and integrated peripherals, combined with extensive low-power modes, are optimized

to achieve extended battery life in portable, battery-powered sensing applications. MSP430FR2000 and

MSP430FR21xx devices offer a migration path for 8-bit designs to gain additional features and functionality from

peripheral integration and the data-logging and low-power benefits of FRAM. Additionally, existing designs using

MSP430G2x MCUs can migrate to the MSP430FR2000 and MSP430F21xx family to increase performance and

get the benefits of FRAM.

The MSP430FR2000 and MSP430FR21xx 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 this MCU meets the needs of applications ranging from appliance battery packs and battery monitoring to

smoke detectors and fitness accessories.

The MSP 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.

MSP430FR2000 and MSP430FR21x 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 and MSP430FR4133 LaunchPad™ development kit and the MSP‑TS430PW20 20-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. MSP430 MCUs are also

supported by extensive online collateral, such as our housekeeping example series, MSP Academy training, and

online support through the TI E2E™ support forums.
