MSP430FR211x devices are an expansion of the MSP430 microcontroller (MCU) value line to the MSP430FRx FRAM-based MCU family with up to 50x the RAM of comparable 8-bit MCUs in a 3-×3-mm2 package. This ultra-low-power MCU family consists of several devices featuring embedded unified memory, which eliminates the need for assembly programming, making it easier to upgrade 8-bit designs in C and take advantage of the benefits of FRAM and integrated peripherals targeted at various 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 that combines the speed, flexibility, and endurance of SRAM with the stability and reliability of flash, all at lower total power consumption. Additionally, existing designs on the MSP430G2x family can migrate to the MSP430F211x family to increase performance and get the benefits of FRAM.
The MSP430FR211x MCU features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators 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 smoke detectors to power tool battery protection and fitness accessories.
System-level ESD protection must be applied in compliance with the device-level ESD specification to prevent electrical overstress or disturbing of data or code memory. See for more information.
