That 180 MHz core clock gives it the throughput to handle real-time control loops, protocol stacks, and data movement without a separate co-processor, but the ROMless architecture means the BOM must include a boot memory device and the PCB must route the external memory bus. ## Sourcing posture The active lifecycle means the factory is still building these, so lead times are typically tied to NXP's standard production cycle rather than a shrinking surplus pool. For a BOM freeze or a line-down replacement, this is a part you can order without worrying about a sudden EOL notice.","metaTitle":"NXP LPC18S30FET256551 ARM Cortex-M3 MCU, 180MHz, 256-LBGA","metaDescription":"NXP LPC18S30FET256551 32-bit ARM Cortex-M3 MCU, 180MHz core, 200K x 8 SRAM, ROMless, industrial temp -40°C~85°C, 256-LBGA.
