16 MHz, 2 KB Flash — the ultra-low-power MCU for sensor and control endpoints
Through-hole package suits prototyping and low-volume production
The 10 general-purpose I/O pins are enough for a few sensors, an LED, and a serial debug header.

Texas Instruments MSP430F2xx MSP430F2011IN, 16-Bit MCU, MSP430 CPU16 core, 16MHz, 2KB Flash, 128 x 8 RAM, 10 I/O, 14-DIP, -40°C to 85°C, 1.8V to 3.6V supply.

The TI F280041PZQR is a 32-bit C2000 C28x MCU rated for automotive environments, but it is not a pin-compatible or direct functional second-source — it uses a different core, runs at 100 MHz, and comes in a surface-mount package. For a through-hole, 16-bit ultra-low-power replacement, stick with other MSP430F2xx DIP variants in the same series.
