That memory split covers moderate firmware images and leaves room for a small parameter store without external EEPROM. The 72 MHz clock delivers enough throughput for real-time control loops, Modbus polling, and basic signal processing — it is not a high-end DSP replacement, but it handles most industrial sensor and actuator tasks. ## Peripheral set and industrial connectivity This MCU integrates CANbus, USB, I²C, SPI, and UART interfaces — the CAN and USB are the key differentiators versus smaller LPC15xx siblings. The 24-channel 12-bit SAR ADC and single 12-bit DAC reduce external analog front-end components for multi-sensor inputs and analog output loops.","metaTitle":"NXP LPC1549JBD100K ARM Cortex-M3 MCU, 72 MHz, 256 KB Flash","metaDescription":"NXP LPC1549JBD100K 32-bit ARM Cortex-M3 MCU at 72 MHz with 256 KB Flash, 36 KB RAM, 4 KB EEPROM, CAN/USB, -40°C to 105°C, 100-LQFP.
