There is no room for a real-time OS, a protocol stack, or any data buffering beyond a handful of variables. The internal oscillator (no external crystal needed) saves two pins and a few cents on the BOM, but the clock accuracy (±1% typical over temp) means timing-critical CAN or LIN nodes still need the external resonator option. ## Package and board-level reality The exposed pad is also the only GND connection for the die, so the solder-joint void rate matters for both thermal and electrical reliability. The tray shipping format is typical for QFN parts; reeling is available on alternate order codes.","metaTitle":"Texas Instruments MSP430G2111IRSAQ1 16-bit MCU, 16 MHz","metaDescription":"Texas Instruments MSP430G2111IRSAQ1 automotive MCU: 16-bit MSP430 core at 16 MHz, 1 KB Flash, 128 B RAM, 10 I/O, 16-QFN, -40°C to 85°C.
