72 MHz Cortex-M3 with on-chip EEPROM
The NXP LPC1548JBD64151 is a 32-bit ARM Cortex-M3 microcontroller running at 72 MHz, with 128 KB Flash, 20 KB RAM, and 4 KB EEPROM on-chip. The EEPROM block saves an external serial memory for calibration constants or boot parameters — one less part on the BOM. The 72 MHz core handles real-time control loops and protocol stacks without breaking a sweat, while the 24-channel 12-bit ADC captures analog inputs from sensors or feedback circuits.
Industrial temperature and connectivity
Supply range is 2.4 V to 3.6 V.
