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
Rated for -40°C to 85°C operation, this MCU suits outdoor telecom cabinets, factory-floor sensor nodes, battery-powered data loggers, and handheld instruments. The 24-VQFN package (3x3 mm) fits tight PCB layouts common in compact probes or smart transmitters. FRAM's write endurance — orders of magnitude beyond Flash — makes it a natural fit for applications that log data continuously or update configuration parameters in the field.
16 MHz — what it means for the control loop
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.
