The 24 KB Flash and 6 KB RAM are enough for a composite HID device or a simple CDC virtual COM port, but you'll want to budget the firmware footprint carefully if you're adding a full USB host stack or multiple endpoints. Housed in a 48-LQFP (7×7 mm) package with a 0.5 mm pitch, it's a hand-solderable surface-mount part — no special reflow profile beyond standard lead-free. TI lists the MSP430F5509IPT as Active. The base product number MSP430F5509 covers the whole density variant; if you need more Flash or RAM later, the MSP430F5xx family has pin-compatible siblings (e.g., the MSP430F5510 with 32 KB Flash) that share the same 48-LQFP footprint.","metaTitle":"MSP430F5509IPT 16-bit MCU, 25 MHz, 24 KB Flash, USB 2.0","metaDescription":"Texas Instruments MSP430F5509IPT 16-bit MCU with USB 2.0, 25 MHz, 24 KB Flash, 6 KB RAM, -40°C to 85°C, 48-LQFP.
