That means the M4 can handle a motor-control FOC loop or audio filter bank while the M0 manages CANbus, USB, and the 118 GPIO lines without contention. For a BOM that needs deterministic real-time response alongside a heavier compute thread, this dual-core split avoids a second MCU and its associated supply chain. ## ROMless — plan for external Flash Program memory type is ROMless, so code lives on an external SPI or parallel Flash. That adds a memory IC and a few PCB traces, but gives flexibility in firmware size and field-update strategy — you are not locked into a fixed on-chip Flash size. The EBI/EMI interface on this part supports parallel NOR/NAND or SRAM, so the external memory bus can also serve as a data buffer. That means it is safe to freeze into a BOM for a multi-year production run.","metaTitle":"NXP LPC43S20FET180E Dual-Core ARM MCU, 204MHz, 180-TFBGA","metaDescription":"NXP LPC43S20FET180E 32-bit dual-core ARM Cortex-M4/M0 MCU at 204MHz, 264K x 8 RAM, ROMless, 118 I/O, CANbus, USB OTG, -40°C to 85°C, 180-TFBGA.
