TI MSP430FR2111IPW16R

MSP430FR2000 and MSP430FR21xx devices belong to the MSP430™ MCU value series detection product portfolio. This ultra-low-power, low-cost MCU series offers FRAM unified memory with memory sizes from 0.5KB to 4KB and features a variety of package options, including a small 3mm x 3mm VQFN package. The architecture, FRAM, and integrated peripherals, combined with multiple low-power modes, are optimized for extending battery life in portable and battery-powered detection applications. The MSP430FR2000 and MSP430FR21xx devices provide a migration path for 8-bit designs to gain additional features and functionality through peripheral integration and the data logging and low-power advantages of FRAM. Additionally, existing designs using the MSP430G2x series MCUs can be migrated to the MSP430FR2000 and MSP430F21xx series to improve performance and leverage the benefits of FRAM.

The MSP ultra-low-power (ULP) FRAM microcontroller platform combines unique embedded FRAM with a comprehensive ultra-low-power system architecture, enabling system designers to enhance performance under low-energy conditions. FRAM technology combines the low-energy fast write, flexibility, and durability of RAM with the non-volatility of flash memory.

The MSP430FR2000 and MSP430FR21x series MCUs are supported by a wide range of hardware and software ecosystems, providing reference designs and code examples to assist users in quickly starting their designs. Development kits include the MSP-EXP430FR2311 and MSP430FR4133 LaunchPad™ development kits and the MSP‑TS430PW20 20-pin target development board. TI also offers free MSP430Ware™ software, which is available as components of the Code Composer Studio™ IDE desktop and cloud versions (located in the TI Resource Explorer). We provide extensive online supporting materials for MSP430 MCUs (such as the general example series and MSP Academy training) and also offer online support through the TI E2E™ support forum.
