The 512 x 8 RAM limits stack depth and buffer allocation. ## Serial connectivity and peripherals The built-in brown-out detect and POR eliminate external reset supervision. A PWM output and watchdog timer round out the peripheral set for simple motor or LED control and system health monitoring. The internal oscillator means no external crystal is needed for basic operation, saving two pins and board space. For dual-sourcing or a performance upgrade, the MSP430F2xx family includes pin-compatible variants with more Flash and RAM — a direct footprint swap without board redesign.","metaTitle":"MSP430F2122IRHBT 16-bit MCU, 4KB Flash, 16 MHz, 32-VQFN","metaDescription":"Texas Instruments MSP430F2122IRHBT 16-bit MCU with 16 MHz core, 4KB Flash, 512B RAM, 24 I/O, industrial temp -40°C to 85°C.
