That split keeps deterministic timing on the control loop even when the communication stack gets busy. ## ROMless — plan for external boot memory No on-chip Flash means the boot image lives in an external SPI NOR Flash or parallel NOR device. That adds a few cents and a PCB trace to the BOM, but it also means firmware updates are straightforward — swap the external memory or reprogram it in-system without worrying about internal Flash endurance. The 264K x 8 SRAM is enough for code shadowing and data buffers in most gateway and HMI applications.","metaTitle":"NXP LPC4350FBD208,551 ARM Cortex-M4/M0 MCU, 204MHz","metaDescription":"NXP LPC4350FBD208,551 32-bit dual-core MCU (ARM Cortex-M4/M0) at 204MHz. 264K x 8 RAM, 142 I/O, Ethernet, CAN, USB OTG, LCD.
