The NXP LPC1822JBD144551 is a 32-bit ARM Cortex-M3 MCU running at 180 MHz, with 512 KB of Flash program memory and 104K x 8 of SRAM. The 16K x 8 EEPROM is a practical detail: parameter storage, calibration constants, or fail-safe logs can live here without wearing the Flash. The 83 GPIOs and the connectivity block — CANbus, USB OTG, multiple SPI/I²C/UART, plus an external bus interface — cover most industrial communication and sensor-fusion needs in a single chip.
