That M4 core handles the DSP-heavy lifting — motor FOC loops, audio processing, or Ethernet packet parsing — while the M0 runs the housekeeping: polling GPIO, managing UART buffers, or waking from sleep. The 1 MB Flash and 154 KB RAM give you room for a full TCP/IP stack plus a GUI frame buffer without squeezing. Industrial temperature range from -40 to 105 °C means this part is rated for the panel inside a factory cabinet or an outdoor telecom enclosure — not just a climate-controlled office PCB. The 164 I/O lines, spread across the 256-LBGA, are enough to drive a parallel LCD, capture encoder quadrature, and still leave pins for CAN and Ethernet. ## Peripherals and connectivity — what's on the die","metaTitle":"NXP LPC43S67JET256551 ARM Cortex-M4/M0 Dual-Core MCU, 204MHz","metaDescription":"NXP LPC43S67JET256551 dual-core MCU: 204MHz Cortex-M4/M0, 1MB Flash, 154KB RAM, 16KB EEPROM, 164 I/O, -40 to 105°C, 256-LBGA.
