Dual-core MCU for real-time control and connectivity
The NXP LPC4367JET256E is a 32-bit dual-core microcontroller built around an ARM Cortex-M4 and an ARM Cortex-M0, running at 204 MHz. It carries 1 MB of Flash program memory, 154K x 8 of RAM, and 16K x 8 of EEPROM, with 164 GPIOs and a broad peripheral set that includes Ethernet, USB OTG, CAN, SPI, UART, I²C, and an LCD controller. The part is rated for the industrial temperature range of -40°C to 105°C and operates from a 2.4 V to 3.6 V supply. It comes in a 256-ball LBGA package (17x17 mm) and is intended for applications such as motor drives, industrial gateways, factory automation, and communication nodes where a mix of real-time control and protocol handling is needed.
The Cortex-M4 handles the DSP and floating-point work at 204 MHz, while the Cortex-M0 offloads housekeeping tasks like I/O scanning or communication framing. This split lets you keep the main control loop deterministic without a second external MCU. The 1 MB Flash is enough for a full protocol stack plus dual-image firmware updates; the 16 KB EEPROM holds calibration or configuration data without wearing the main Flash.
Connectivity and I/O — fits a multi-protocol node
Ethernet, USB OTG, and CANbus are on-chip, so a single LPC4367JET256E can serve as a fieldbus gateway or a motor-drive controller with remote monitoring. The 164 GPIOs and external bus interface (EBI/EMI) allow parallel connection to an external display or SRAM. The 16-channel 10-bit ADC covers analog inputs like current sense or thermistor feedback.
