The 128-byte RAM ceiling means the stack depth and any data buffer must be budgeted byte by byte. A nested interrupt with two levels and a 32-byte FIFO consumes most of it; plan the call tree before writing a line of C. ## On-chip peripherals reduce BOM count The integrated Brown-out Detect/Reset (BOR), Power-on Reset (POR), and Watchdog Timer (WDT) eliminate the need for an external supervisor IC in most low-power designs. A single PWM output is available for driving a small LED or a piezo buzzer directly from the GPIO. With only 10 I/O pins, the part suits applications that need a handful of digital inputs, one or two analog reads (via the comparator or ADC — note that no on-chip ADC is listed in the spec record), and a serial interface. The I/O count is the limiting factor for any multi-sensor or keypad matrix design. ## Active production — no lifecycle risk for new builds Texas Instruments lists the MSP430G2111IRSA16T as Active with no end-of-life notice. ROHS3 compliant, it carries no RoHS exemption expiry concerns.","metaTitle":"TI MSP430G2111IRSA16T MCU, 16 MHz, 1 KB Flash, 16-QFN","metaDescription":"Texas Instruments MSP430G2111IRSA16T 16-bit MCU, 16 MHz, 1 KB Flash, 128 B RAM, 10 I/O, 1.8-3.6 V, -40 to 85°C, 16-QFN.

It shares the same 16 MHz CPU16 core and 10 I/O count, but adds 2 KB Flash, 128 B RAM, and an integrated 8-channel 10-bit ADC. The package differs (14-TSSOP vs 16-QFN), so a board layout change is required.
