If your firmware already runs on a 32 KB part in the same family, the MSP430F5505IRGZT is a cost-down target only if the code fits — verify the.text and.rodata sections before committing the BOM line. ## USB 2.0 plus serial — replaces a separate bridge IC The integrated USB 2.0 controller, combined with I²C, SPI, and UART ports, lets this MCU talk directly to a PC or host processor while also managing local sensors and actuators. That eliminates a dedicated USB-to-UART or USB-to-SPI bridge chip, saving about $0.50–$1.00 in BOM cost and reclaiming board area. The 31 general-purpose I/O pins are enough to interface with a keypad, small display, or a handful of digital sensors alongside the USB connection. This reduces supply-chain risk for designs that will run for several years. ## 48-VQFN package — thermal and layout notes The 31 I/O pins are routed on a 0.5 mm pitch, so a 4-layer board with microvias is not mandatory, but a solid ground plane under the QFN is recommended for signal integrity, especially with USB running at 12 Mbps.","metaTitle":"MSP430F5505IRGZT 16-bit MCU, 25 MHz, 16 KB Flash, USB","metaDescription":"Texas Instruments MSP430F5505IRGZT 16-bit MCU, 25 MHz, 16 KB Flash, 6K RAM, USB 2.0, I²C/SPI/UART, -40°C to 85°C, 48-VQFN.
