The M4 handles the application thread — protocol stacks, control loops, signal processing — while the M0 offloads housekeeping like DMA sequencing, I²C polling, or wake-up logic. That split frees the M4 from interrupt overhead on low-priority bus traffic. For a system that must service Ethernet, CAN, and USB OTG concurrently without jitter on the motor-control PWM, this architecture buys deterministic timing on the M4 side without a second chip. ## ROMless — plan the external memory budget This part carries no on-chip program memory — the 264 KB SRAM is data memory only. The EBI/EMI interface connects to external NOR Flash, NAND, or SRAM. NXP lists the LPC43S30FET256551 as Active. No last-time-buy notice or successor part number on record.","metaTitle":"NXP LPC43S30FET256551 ARM Cortex-M4/M0 MCU, 204MHz","metaDescription":"NXP LPC43S30FET256551 dual-core 32-bit MCU, 204MHz, 264KB SRAM, ROMless, 164 I/O, CAN/Ethernet/USB OTG, -40°C to 85°C, 256-LBGA.
