25 MHz CPUXV2 core with USB — what the peripheral set means for your design
The MSP430F5504IPTR: The USB 2.0 peripheral (full-speed, device-only) is the standout feature on this MSP430F5xx part, alongside I²C, SPI, UART, IrDA, and LINbus connectivity. The 48-LQFP package exposes 31 general-purpose I/O pins and an 8-channel 10-bit ADC.
8 KB Flash and 6K x 8 RAM — memory budget check
With 8 KB of Flash and 6K x 8 of RAM, this MCU is not a candidate for large application stacks or heavy data buffering. The firmware architect should budget the USB stack footprint early — the full-speed USB library plus a minimal application can fit, but adding a real-time OS or large lookup tables will push past the available Flash. The 6K x 8 RAM supports moderate-sized packet buffers for USB transactions; plan for double-buffering if throughput matters.
Industrial temperature grade and operating voltage
Brown-out detect and POR are integrated, so external reset supervision is not required.
