It includes Ethernet, USB OTG, CANbus, and an 8-channel 12-bit ADC. ## 120 MHz clock – what it means for protocol stack headroom At 120 MHz, the Cortex-M4 runs an Ethernet TCP/IP stack alongside a CANopen or Modbus RTU stack. The 96 KB RAM must cover packet buffers, USB descriptors, RTOS kernel, and data arrays. ## 208-TFBGA – board design considerations The 208-ball TFBGA (15x15 mm) requires a PCB capable of routing 165 signals plus power and ground. A four-layer board with buried vias is the practical minimum.","metaTitle":"NXP LPC4078FET208551 ARM Cortex-M4 MCU, 120MHz","metaDescription":"NXP LPC4078FET208551 ARM Cortex-M4 MCU, 120MHz, 512KB Flash, 96KB RAM, Ethernet, USB OTG, CAN, 165 I/O, -40°C to 85°C, 208-TFBGA.
