It integrates a USB 2.0 full-speed device controller with the PHY on-die, so no external transceiver is needed for HID, CDC, or vendor-specific USB interfaces. The 26 GPIOs in a 32-HVQFN package suit compact control boards where USB connectivity and a small footprint are both required. ## EEPROM and analog integration The 4 KB EEPROM stores calibration constants, device serial numbers, or boot parameters without an external 24LCxx part — saves a footprint and a serial bus slot. ## Peripheral set and serial interfaces Connectivity includes I²C, SPI/SSP, UART, and SmartCard interfaces alongside USB. The brown-out detect and POR supervisor eliminates an external reset IC for most designs.","metaTitle":"LPC11U34FHN33/421, NXP LPC11U34FHN33/421 ARM Cortex-M0 MCU, 50 MHz, 48 KB Flash","metaDescription":"NXP LPC11U34FHN33/421 32-bit ARM Cortex-M0 MCU at 50 MHz with 48 KB Flash, 10 KB RAM, 4 KB EEPROM, USB 2.0 FS.
