The 4 KB EEPROM (4 K × 8) is the key differentiator versus the base LPC11xx parts: it stores calibration constants, node ID, or fault logs without wearing the Flash. The 10 KB SRAM (10 K × 8) supports a few hundred bytes of stack plus a modest data buffer for a UART or I²C transaction. If the application needs a large frame buffer or a TCP/IP stack, the RAM will be the binding constraint. The part includes I²C, SPI/SSI/SSP, and UART/USART blocks, plus a Microwire interface.","metaTitle":"NXP LPC11E14FHN33/401 ARM Cortex-M0 MCU, 50 MHz, 32 KB Flash","metaDescription":"NXP LPC11E14FHN33/401 32-bit ARM Cortex-M0 MCU, 50 MHz speed, 32 KB Flash, 10 KB RAM, 4 KB EEPROM, -40 to 85°C.
