50 MHz core speed is the entry-level tier in the LPC11Uxx family. Runs a USB stack with a small application loop and polls sensors over I²C.
16 KB Flash and 6 KB RAM (6K x 8). USB device library uses 6-8 KB Flash; plan firmware size early.
The ARM Cortex-M0 core runs at 50 MHz, which is the entry-level speed for the LPC11Uxx family. It's sufficient for USB device applications and moderate control loops.
