The NXP LPC8N04FHI24E is a 32-bit ARM Cortex-M0+ MCU in the LPC8Nxx series, clocked at 8 MHz with 32 KB Flash, 8 KB RAM, and 4 KB EEPROM on-chip. It runs from 1.72 V to 3.6 V and is rated for -40°C to 85°C — the industrial temperature band that covers most factory-floor sensors, IoT edge nodes, and battery-operated control modules. The 24-HVQFN (4x4 mm) exposed-pad package keeps the footprint small, and the 12 I/O lines, plus I²C and SPI connectivity, suit simple sensor readout or actuator-driver designs where you want to avoid external EEPROM for calibration constants.
Memory mix — why the EEPROM matters
The 4 KB EEPROM block is the standout here versus many Cortex-M0+ parts that only offer Flash and RAM. That means you can store calibration tables, node IDs, or wear-leveled logs without an external serial EEPROM — saving one IC and two I/O lines.
