It also integrates 4 KB of EEPROM for non-volatile parameter storage, plus an 8-channel 12-bit ADC. The 48-LQFP package with 36 I/Os and a 2.4 V to 3.6 V supply range makes it a fit for industrial control, sensor aggregation, and human-machine interface panels where moderate throughput and a hand-solderable footprint are priorities. ## On-chip peripherals and connectivity Connectivity covers I²C, SPI, SSI, SSP, and UART/USART, so it can talk to common sensors, displays, and serial memories. The 8-channel 12-bit ADC handles analog inputs like potentiometers, thermistors, or current-sense resistors without an external converter.","metaTitle":"NXP LPC11E66JBD48551 ARM Cortex-M0+ MCU, 50 MHz, 64 KB Flash","metaDescription":"NXP LPC11E66JBD48551 32-bit ARM Cortex-M0+ MCU, 50 MHz core, 64 KB Flash, 12 KB SRAM, 4 KB EEPROM, 48-LQFP, -40 to 105°C.
