The 12 KB SRAM supports moderate buffering for I²C or SPI data streams; designs needing larger frame buffers should plan external memory or step to a higher-RAM sibling. ## On-chip EEPROM and integrated peripherals The 4 KB EEPROM allows storing calibration constants, device IDs, or configuration parameters without external serial memory — a BOM simplification for production. An internal oscillator is available, though an external crystal can be used for tighter timing.","metaTitle":"NXP LPC11E66JBD48E551 ARM Cortex-M0+ MCU, 50MHz, 64KB Flash, 48-LQFP","metaDescription":"NXP LPC11E66JBD48E551 32-bit MCU with 50MHz ARM Cortex-M0+ core, 64KB Flash, 12KB SRAM, 4KB EEPROM, 48-LQFP, -40°C to 105°C.
