If your firmware already compiles to 6 KB on a similar part, this is the cost-optimized choice. If you are porting code from a larger MSP430, expect to strip out unused drivers or move lookup tables to external serial Flash. The 6 KB RAM is organized as 6K x 8 — enough for a modest USB buffer and a few sensor arrays, but not for large frame buffers or audio recording. ## USB + serial — the interface mix This MCU includes a full-speed USB 2.0 module with an integrated PHY, plus I²C, SPI, UART, and LINbus. The USB block handles up to eight endpoints and supports suspend/resume with a dedicated oscillator. For designs that need to talk to a PC over USB and also poll sensors over I²C or SPI, the MSP430F5500IRGZT handles both without an external bridge chip. Surface-mount only, so no socketed prototyping — budget for an adapter board or a small-run QFN breakout.","metaTitle":"TI MSP430F5500IRGZT 16-bit MCU, 25 MHz, 8 KB Flash, 48-VQFN","metaDescription":"Texas Instruments MSP430F5500IRGZT 16-bit MCU, 25 MHz core, 8 KB Flash, 6 KB RAM, USB + serial connectivity, -40°C to 85°C, 48-VQFN.
