120 MHz Cortex-M4 with integrated Ethernet and CAN
The NXP LPC4078FBD100K is a 32-bit ARM Cortex-M4 MCU running at 120 MHz, with 512 KB Flash, 96 KB RAM, and 4 KB EEPROM on-chip. It carries Ethernet, CAN, and USB OTG interfaces, plus an 8-channel 12-bit SAR ADC and a single 10-bit DAC. The part is specified for -40°C to 85°C operation on a 2.4 V to 3.6 V supply, housed in a 100-LQFP (14×14 mm) package.
Memory and peripheral mix for industrial gateways
The 4 KB EEPROM is a notable inclusion — it saves an external serial EEPROM for calibration constants or boot parameters. The 96 KB RAM is adequate for moderate TCP/IP stacks or CAN message buffers, but designs with heavy graphics or large data logs will need external memory via the EBI/EMI interface.
Connectivity and analog I/O for control applications
With Ethernet, CAN, USB OTG, and multiple UART/SPI/I²C channels, this MCU fits well in industrial controllers, remote I/O gateways, and HMI panels. The 8-channel 12-bit SAR ADC and single 10-bit DAC cover analog sensor input and control output without an external converter. The internal oscillator reduces BOM count for non-critical timing.
