The 256-byte RAM limits data buffering — expect to manage variables tightly and avoid large lookup tables. For designs that need more headroom, the MSP430G2xx family includes pin-compatible parts with up to 16 KB Flash and 512 B RAM, but the package and peripheral set remain the same. At the low end, 1.8 V operation allows the MCU to run directly from a nearly depleted battery, extending system runtime. The 24 general-purpose I/O pins, all with interrupt capability, are enough for keypad scanning, LED driving, and simple parallel interfaces. The 32-VFQFN package (5x5 mm body, exposed pad) is a compact surface-mount option for space-constrained PCBs. It is ROHS3 compliant.","metaTitle":"TI MSP430G2303IRHB32T 16-bit MCU, 16 MHz, 4 KB Flash","metaDescription":"Texas Instruments MSP430G2303IRHB32T 16-bit MCU, 16 MHz core, 4 KB Flash, 256 B RAM, 24 I/O, I²C/SPI/UART, -40°C to 85°C, 32-VQFN.

Both share the same 16-bit CPU core, 16 MHz speed, 24 I/O, and 32-VQFN package option, so a board layout can be reused.
