180 MHz Cortex-M3 with integrated motor-control peripherals
The NXP LPC1813JBD144E is a 32-bit ARM Cortex-M3 microcontroller from the LPC18xx series, clocked at 180 MHz. It carries 512 KB of Flash, 104 KB of SRAM, and 16 KB of on-chip EEPROM — enough program space for a moderate motor-control algorithm plus a communication stack, with the EEPROM handling calibration constants and fault logs without external storage. Rated for -40°C to 105°C, this MCU fits motor drives in factory automation and outdoor telecom base-station controllers.
Memory map and field-update strategy
The 512 KB Flash is sufficient for a single firmware image with a small bootloader; if you need dual-bank for over-the-air updates, the 104 KB SRAM can buffer a new image while the old one runs. The 16 KB EEPROM is byte-addressable and rated for higher endurance than Flash — use it for trim values, production serial numbers, and fault counters that change every power cycle.
