The M4 handles the main application and DSP work; the M0 offloads peripheral management, I/O scanning, and communication protocol handling. This split keeps real-time loops deterministic even when the connectivity stack is busy. On-chip memory includes 512 KB of Flash for firmware, 104 KB of SRAM for data buffers, and 16 KB of EEPROM for configuration parameters that survive power loss. The EEPROM block means no external serial EEPROM for calibration or network-node identity storage — one fewer BOM line. Connectivity covers CAN, USB OTG, Ethernet, multiple UART/USART, I²C, SPI, and SSI — enough to bridge a fieldbus gateway, talk to a VFD over Modbus RTU, and log data to a USB stick simultaneously. The 83 general-purpose I/O give headroom for panel indicators, relay drivers, and sensor inputs without an I/O expander. The Cortex-M4 runs at 204 MHz. The Cortex-M0 handles CAN and UART interrupts at the same clock. Supply range is 2.2 V to 3.6 V. Package is 144-LQFP (20x20 mm), surface-mount, tray delivery.","metaTitle":"NXP LPC4323JBD144E ARM Cortex-M4/M0 MCU, 204 MHz, 512 KB Flash","metaDescription":"NXP LPC4323JBD144E 32-bit dual-core MCU: ARM Cortex-M4/M0 at 204 MHz, 512 KB Flash, 104 KB SRAM, 83 I/O, -40 to 105°C.
