Plan for register-based or Flash-constant data wherever possible. With 16 I/O lines in a 24-VFQFN Exposed Pad package, it suits space-constrained boards. The MSP430F2xx series has been in volume production for years, and TI continues to support it with development tools and documentation. ## Package and footprint — 24-VQFN with exposed pad The 24-VFQFN Exposed Pad package (4x4 mm body) requires a via-stitched ground pad on the PCB for thermal relief and electrical grounding. The pad is internally connected to VSS — do not route signals underneath it. Surface-mount assembly is straightforward with standard reflow profiles.","metaTitle":"TI MSP430F2121IRGET 16-Bit MCU, 16 MHz, 4 KB Flash, 24-VQFN","metaDescription":"Texas Instruments MSP430F2121IRGET 16-bit MCU with 16 MHz core, 4 KB Flash, 256 B RAM, industrial temp -40°C to 85°C.
