There is no room for a bootloader with over-the-air update capability; plan for factory-programmed firmware or a separate external EEPROM for field-configurable parameters. ## 16-QFN package — reflow considerations The 4x4 mm QFN with exposed pad requires a thermal land pattern on the PCB and a stencil aperture that deposits enough solder paste under the die paddle. Check the MSL rating before the reflow line. ## Lifecycle status — EOL hot The MSP430F2003TRSAR carries an EOL-hot lifecycle flag, meaning Texas Instruments has issued a last-time-buy notice. Buyers should secure their lifetime- or bridge-buy quantities now or plan a pin-compatible migration within the MSP430F2xx family.","metaTitle":"TI MSP430F2003TRSAR 16-bit MCU, 16 MHz, 1 KB Flash, 16-QFN","metaDescription":"Texas Instruments MSP430F2003TRSAR 16-bit ultra-low-power MCU, 16 MHz, 1 KB Flash, 128 B RAM, I2C/SPI, -40 to 105°C.
