The DMA controller can move USB packet payloads directly to RAM. ## Memory budget and USB role 24 KB of Flash and 6 KB of RAM set a clear application boundary: this part fits a USB-to-serial bridge, a data-logging front-end with local buffering, or a simple HID-class device. It will not run a USB mass-storage stack with a file system — the RAM is too tight for large sector buffers. ## Date-code and provenance check","metaTitle":"TI MSP430F5509IPTR 16-bit MCU, 25 MHz, 24 KB Flash, USB, 48-LQFP","metaDescription":"TI MSP430F5509IPTR 16-bit MSP430 MCU, 25 MHz, 24 KB Flash, 6 KB RAM, USB 2.0, 48-LQFP.
