It packs 256 KB of Flash, 36 KB of RAM, and 4 KB of EEPROM on-chip, along with a 16-channel 12-bit ADC. ## Where it fits in the BOM The 72 MHz Cortex-M3 core with 256 KB Flash and 36 KB RAM handles CANopen nodes or USB data loggers. The 4 KB EEPROM saves an external serial EEPROM for calibration constants. The 30 I/O lines in the 48-LQFP package are adequate for a modest sensor array or a motor-control interface with encoder feedback. The internal oscillator saves an external crystal if timing accuracy within the part's specification is acceptable.","metaTitle":"NXP LPC1549JBD48151 ARM Cortex-M3 MCU, 72 MHz, 256 KB Flash","metaDescription":"NXP LPC1549JBD48151 32-bit ARM Cortex-M3 MCU: 72 MHz, 256 KB Flash, 36 KB RAM, 4 KB EEPROM, CAN/USB/SPI/I²C, -40 to 105 °C, 48-LQFP.
