It targets simple state machines, debounced switch reads, a single PWM fan-control loop, or a LIN-bus node message handler. The 128 x 8 RAM is enough for a few local variables and a small stack — any significant data buffering or lookup table lives in Flash. If the firmware grows past 1 KB, step up to the MSP430G2201 or G2231 in the same QFN footprint. ## Package and temperature grade — survives the oven and the road","metaTitle":"TI MSP430G2101IRSAQ1 16-bit MCU, 16MHz, 1KB Flash, AEC-Q100","metaDescription":"Texas Instruments MSP430G2101IRSAQ1 16-bit MCU with 16MHz core, 1KB Flash, 128B RAM, AEC-Q100 automotive qualified, -40°C to 85°C.
