Product details

100 MHz Cortex-M0+ with on-chip EEPROM

The NXP LPC51U68JBD64EL is a 32-bit ARM Cortex-M0+ MCU running at 100 MHz, with 256 KB Flash, 96 KB RAM, and 32 KB EEPROM on-chip. The EEPROM saves a separate serial memory for calibration constants or configuration parameters — one less BOM line for a parameter-storage IC. The 48 GPIOs and USB, USART, SPI, and I2C interfaces cover typical sensor-fusion or human-machine-interface tasks in industrial control panels or appliance PCBs.

No last-time-buy or obsolescence notice on record. For multi-year production runs, this part is a stable BOM anchor.
