16-bit FRAM MCU for low-power control and data logging
The Texas Instruments MSP430FR2111IRLLT is a 16-bit MCU clocked at 16 MHz with 3.75 KB of FRAM program memory and 1 KB of RAM.
Where it fits — industrial sensing, portable instruments, metering
16 MHz is a moderate clock speed for a 16-bit MCU. It handles sensor polling at a few kilohertz, simple PID loops, and UART/SPI communication without timing pressure. If your application needs heavy DSP or fast interrupt response, the MSP430FR2xxx family offers higher clock options — but for a typical low-power sensor node or metering endpoint, 16 MHz keeps the active current low and the battery life long.
