This speed rating sets the instruction throughput ceiling — at 16 MHz the core executes up to 16 MIPS, enough for sensor polling, serial protocol handling, and low-duty-cycle control loops. ## Memory budget and peripheral set On-chip memory is 2 KB of Flash (2K x 8) and 128 bytes of RAM (128 x 8). The Flash holds firmware and constant data; the 128-byte RAM limits runtime variables to small buffers — a typical application might use 64 bytes for a sensor readout and 32 bytes for a communication frame, leaving 32 bytes for the stack. I2C and SPI connectivity are available via the serial interface module, and 10 general-purpose I/O pins are brought out to the 14-TSSOP package. ## On-chip supervisory and timing peripherals Integrated peripherals include brown-out detect and power-on reset (POR), a watchdog timer (WDT), and a PWM module. The brown-out detect holds the core in reset when Vcc drops below the threshold, preventing code corruption during power transients. The WDT provides a last-resort recovery from firmware hangs — a common requirement in unattended sensor nodes. ## Active lifecycle and sourcing posture The part is ROHS3 compliant.","metaTitle":"Texas Instruments MSP430G2221IPW14 MCU, 16 MHz, 2 KB Flash","metaDescription":"Texas Instruments MSP430G2221IPW14 16-bit MCU, 16 MHz core, 2 KB Flash, 128 B RAM, 14-TSSOP.
