180 MHz Cortex-M3 — what the speed buys you
The 180 MHz core is the fastest clock available in the LPC18xx series. It directly determines how much headroom you have for real-time control loops, TCP/IP stack processing, or display refresh. At this speed, a single-cycle multiply or a 16-bit timer capture runs without stalling the CPU — useful when the part is handling both a CANopen stack and a PWM motor-control interrupt simultaneously.
Memory sizing: 1 MB Flash, 136 KB RAM, 16 KB EEPROM
The 1 MB Flash is enough for a dual-image firmware layout (bootloader + application) with room for a small file system. The 136 KB SRAM is split across multiple banks; it can hold a 640x480 frame buffer at 16-bit colour if you use the external bus for the display controller.
