The USB controller is device-only; no host or OTG. Serial interfaces include SSP (synchronous serial) and Microwire compatibility, which broadens peripheral options beyond standard SPI.","metaTitle":"NXP LPC11U14FHI33/201551 ARM Cortex-M0 MCU, 50 MHz, 32 KB Flash","metaDescription":"NXP LPC11U14FHI33/201551 32-bit ARM Cortex-M0 MCU, 50 MHz, 32 KB Flash, 6 KB RAM, USB, industrial temp -40 to 85°C.
