16 MHz MSP430 core in a through-hole DIP — what it fits
The Texas Instruments MSP430F2002TN is a 16-bit ultra-low-power microcontroller from the MSP430F2xx family, clocked at 16 MHz. It carries 1 KB of Flash program memory and 128 bytes of RAM — enough for a single sensor node, a simple I²C/SPI bridge, or a low-speed control loop. The 8-channel 10-bit ADC on board reads analog inputs directly, so you can skip an external converter for thermistor or potentiometer signals. The 14-pin PDIP package (0.300" body) is a through-hole footprint — breadboard-friendly, easy to hand-solder, and reworkable in the field. It is not a space-saver; expect to allocate board area for the socket or solder pads. The industrial temperature range of -40 to 105 °C qualifies it for outdoor telecom cabinets, factory-floor sensor heads, and engine-bay auxiliary modules where ambient heat cycles are routine. Peripherals include brown-out detect/reset, POR, PWM, and WDT. The internal oscillator runs at 16 MHz.
Lifecycle — last-time-buy window is open
The MSP430F2002TN is flagged as end-of-life hot (EOL hot). Procurement should secure a lifetime buy or identify a migration path now.
