The 26 general-purpose I/O lines, combined with an internal oscillator and brown-out detect, allow a minimal BOM: just the MCU, decoupling caps, and the USB connector for many applications.","metaTitle":"NXP LPC11U34FHN33/311551 ARM Cortex-M0 MCU, 50 MHz, 40 KB Flash","metaDescription":"NXP LPC11U34FHN33/311551 32-bit ARM Cortex-M0 MCU, 50 MHz, 40 KB Flash, 8 KB RAM, 4 KB EEPROM, USB, industrial temp -40 to 85 °C, HVQFN-32.
