The M4 handles the math-heavy control loop — motor FOC, sensor fusion, or protocol stack — while the M0+ offloads housekeeping like I²C polling, UART framing, or wake-up sequencing. That split keeps the main loop deterministic without a separate CPLD or small MCU for glue logic. ## Memory budget for a motor-drive or HMI BOM 512 KB of flash and 104 KB of SRAM are sized for a single motor-control firmware image with CANopen stack and a modest HMI page buffer. The 16 KB EEPROM block holds calibration constants and fault logs without external serial EEPROM. ## Peripheral set for industrial connectivity Two CANbus controllers, USB OTG with host/device capability, and a motor-control PWM timer with dead-time insertion cover the typical drive and gateway I/O. The EBI/EMI bus can connect external SRAM, NOR flash, or an FPGA for custom logic expansion. 83 GPIOs leave headroom for a keypad, encoder inputs, and status LEDs without a port expander.","metaTitle":"NXP LPC4322JBD144551 ARM Cortex-M4/M0 MCU, 204 MHz, 512KB Flash","metaDescription":"NXP LPC4322JBD144551 dual-core ARM Cortex-M4/M0 MCU at 204 MHz with 512KB flash, 104KB SRAM, 83 I/O, -40°C to 105°C, 144-LQFP.
