Product details

The LPC11U34FHN33/421,: The LPC11U34FHN33/421: The NXP LPC11U34FHN33/421 is a 32-bit ARM Cortex-M0 MCU running at 50 MHz, with 48 KB Flash, 10 KB RAM, and 4 KB EEPROM on-chip. 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.
