For a typical sensor node reading a temperature probe and reporting over I²C every second, that is plenty. The 512 bytes of RAM (organized as 512 x 8) is the working data space: stack, global variables, and buffers. If your application uses a large lookup table or a long UART buffer, you will hit the ceiling fast. The 16 MHz core clock is fast enough for most low-power polling loops and moderate data rates, but there is no hardware multiplier or FPU — heavy math takes multiple cycles. This part comes in a 32-VFQFN Exposed Pad package (5 mm x 5 mm body, supplier package 32-VQFN). Surface-mount only, so no socketed field swap without a hot-air station.","metaTitle":"MSP430G2403IRHB32T 16-bit MCU, 8KB Flash, 16 MHz, 32-VQFN","metaDescription":"Texas Instruments MSP430G2403IRHB32T 16-bit MCU: 16 MHz, 8KB Flash, 512B RAM, 1.8V-3.6V, 24 I/O, 32-VQFN.
