The NXP LPC4313JBD144551 is a 32-bit dual-core microcontroller built around an ARM Cortex-M4 and a Cortex-M0, running at 204 MHz. The M4 handles the heavy lifting — math-intensive control algorithms, FFTs, and communication protocol stacks — while the M0 offloads housekeeping tasks like GPIO toggling, timer management, and low-power wake-up routines. This asymmetric architecture lets a single chip manage both a motor-control loop and a fieldbus gateway without a second processor. Program memory is 512 KB of on-chip Flash, backed by 104 KB SRAM and 16 KB EEPROM for parameter storage. That Flash footprint is sized for a full CANopen or Modbus stack plus a sensor-fusion library, with room left for bootloader and field-upgrade logic. The I²S interface makes it a candidate for audio processing or voice-command front-ends in industrial HMI panels.
Peripheral set and I/O budget
For BOM planning, the base product number is LPC4313.
What the 204 MHz rating means for your BOM
The dual-core split lets the M0 run a Modbus RTU poll loop while the M4 executes a field-oriented control algorithm.
