Integrates 4 KB on-chip EEPROM, 36 I/O lines, and an 8-channel 12-bit ADC. Rated for -40°C to 105°C and 2.4 V to 3.6 V. ## 50 MHz — what it buys you on the bus At 50 MHz the Cortex-M0+ core executes single-cycle I/O toggles and handles a couple of UART or SPI streams without a DMA bottleneck. The 12 KB RAM is enough for a modest RTOS heap and a few protocol buffers, but if you need to buffer a full TCP stack or run a GUI framebuffer, you will bump into the ceiling. The 4 KB EEPROM saves an external serial EEPROM for calibration constants or boot parameters — a real BOM shrink for a panel controller that stores offset trims or node addresses. ## Active, no LTB watch needed Active lifecycle status. No last-time-buy or obsolescence notice.","metaTitle":"NXP LPC11E66JBD48E 32-bit ARM Cortex-M0+ MCU, 50MHz, 64KB Flash, 48-LQFP","metaDescription":"NXP LPC11E66JBD48E 32-bit ARM Cortex-M0+ MCU at 50MHz with 64KB Flash, 12KB RAM, 4KB EEPROM, 36 I/O, 8x12-bit ADC, -40°C to 105°C.
