That means you can plug a USB flash drive into the MCU or connect it to a PC for firmware updates — both without an external USB controller. The internal oscillator handles USB timing, so no external crystal is required for full-speed operation.","metaTitle":"NXP LPC1343FHN33,551 ARM Cortex-M3 MCU, 72MHz","metaDescription":"NXP LPC1343FHN33,551 32-bit ARM Cortex-M3 MCU, 72MHz, 32KB Flash, 8KB RAM, USB OTG, -40 to 85°C.
