It is part of the LPC11Exx series and comes in a 64-LQFP package with 50 general-purpose I/O pins. The part is rated for the industrial temperature range of -40°C to 105°C, making it suitable for motor-drive, outdoor telecom, and factory-automation environments where the ambient temperature can swing. On-chip peripherals include brown-out detect, DMA, POR, PWM, and a watchdog timer, plus connectivity interfaces covering I²C, SPI, UART, and Microwire. ## 256 KB Flash and 36 KB RAM — sizing the firmware and data buffers The 256 KB Flash is enough for a bootloader plus a moderate application stack — think a Modbus RTU gateway with a few hundred registers of tag-mapped variables. The 36 KB RAM handles runtime data, stack, and DMA buffers without spilling to external SRAM. The 4 KB EEPROM stores calibration constants or configuration parameters that survive a firmware update, so you avoid an external serial EEPROM on the board. ## Industrial temperature grade and package fit The -40°C to 105°C operating range covers engine-bay, rooftop, and factory-floor installations. The 64-LQFP (10x10 mm) is a standard footprint for mid-density MCUs.","metaTitle":"NXP LPC11E68JBD64551 ARM Cortex-M0+ MCU, 50 MHz, 256 KB Flash","metaDescription":"NXP LPC11E68JBD64551 32-bit ARM Cortex-M0+ MCU, 50 MHz, 256 KB Flash, 36 KB RAM, 4 KB EEPROM, 50 I/O, 64-LQFP, -40°C to 105°C.
