Sixteen general-purpose I/O lines with PWM and a brown-out reset cover basic actuator and monitoring tasks. ## Memory budget — what fits and what doesn't With 2 KB of Flash and 256 bytes of RAM, this is a parts-count-conscious MCU. A UART-based bootloader, a basic state machine, and a few ADC reads will fit. A full TCP/IP stack, a USB host driver, or a large lookup table will not. The 256-byte RAM means careful allocation of ring buffers and stack depth — a single 128-byte buffer eats half the available RAM. For designs that need more headroom, the MSP430G2xx family offers pin-compatible parts with up to 16 KB Flash and 512 B RAM without changing the 20-TSSOP footprint. ## Connectivity and peripherals for the job The brown-out detect and watchdog timer keep the system running cleanly through supply glitches — important for battery-powered or intermittently powered equipment. PWM outputs on the 16 I/O lines can drive a small DC motor or LED string directly with a transistor buffer. Housed in a 20-TSSOP package (4.40 mm wide, 0.65 mm pitch), this MCU is a surface-mount part that reflows with standard lead-free profiles.","metaTitle":"MSP430G2203IPW20 16-Bit MCU, 16 MHz, 2 KB Flash, 20-TSSOP","metaDescription":"Texas Instruments MSP430G2203IPW20 16-bit MCU with 16 MHz core, 2 KB Flash, 256 B RAM, 1.8V–3.6V supply, -40°C to 85°C.
