The 1.8V to 3.6V supply range lets it run directly from a single lithium cell or a regulated 3.3V rail common in automotive ECUs. ## AEC-Q100 and the 16-QFN footprint ## Obsolete — sourcing reality and the replacement path Both carry the same AEC-Q100 qualification and 16-QFN package option. For BOM lines already qualified to this exact code, the only channel is independent distribution — last-time-buy stock is exhausted through franchised distribution. If your design can absorb a firmware re-spin, moving to a current MSP430G2 variant removes the single-source risk.","metaTitle":"TI MSP430G2221IRSAQ1 16-bit MCU, 16MHz, 2KB Flash, AEC-Q100","metaDescription":"Texas Instruments MSP430G2221IRSAQ1 automotive 16-bit MCU. 16MHz core, 2KB Flash, 128B RAM, I2C/SPI, AEC-Q100.
