The NXP LPC1822JBD144E is a 32-bit ARM Cortex-M3 MCU running at 180 MHz, with 512 KB of Flash program memory and 104 KB of SRAM. The 512 KB Flash and 104 KB SRAM split is sized for a single firmware image with room for field-upgradeable application code and a moderate data buffer — think a servo drive with parameter tables, or a PLC slave node holding a few hundred I/O mapping records. That means you can hang an external SRAM or FPGA on the EBI, talk to a VFD over CAN, and handle USB firmware updates through the same chip — no separate USB controller needed.
