The 50 MHz core speed is the maximum throughput for this single-core device; it sets the timing closure budget for interrupt latency and peripheral bus access in a control-loop or sensor-fusion application. ## On-chip EEPROM — one less external part The 4 KB EEPROM is integrated on the same die as the Flash and RAM, so configuration parameters or calibration constants stay non-volatile without a separate serial EEPROM footprint. That saves a 2x2 mm package and one I²C or SPI bus on the board. The 10 KB RAM is modest — enough for a real-time control stack or a small RTOS, but not for large frame buffers or heavy data logging. ## Obsolete — sourcing reality for this MCU ## Peripherals and connectivity — what is on the bus The peripheral set includes I²C, SPI, SSP, UART/USART, and SmartCard interfaces — enough for a Modbus RTU slave, a serial display, or a sensor hub.","metaTitle":"NXP LPC11E37HFBD64/4QL ARM Cortex-M0 MCU, 50 MHz, 128 KB Flash","metaDescription":"NXP LPC11E37HFBD64/4QL 32-bit ARM Cortex-M0 MCU, 50 MHz, 128 KB Flash, 10 KB RAM, 4 KB EEPROM, 54 I/O, 64-LQFP, -40°C to 85°C.
