The three-tier memory architecture lets the firmware image, runtime data buffers, and calibration constants each live in their own storage domain — no external EEPROM needed for parameter retention. ## What the memory partition means for the BOM The 256 KB Flash holds a moderate firmware stack — enough for a CANopen or Modbus RTU stack plus application logic. The 36 KB RAM supports two or three moderate-size data buffers without pushing into external SRAM. The 4 KB EEPROM is useful for calibration coefficients, production serial numbers, or fault logs that must survive a power cycle. Budget the ECC if you cycle the Flash near its documented endurance — the on-chip Flash controller handles it, but the firmware must not treat the EEPROM emulation as unlimited-write RAM. ## Peripheral set for industrial communication CANbus, USB, I²C, SPI, and UART/USART are all on-chip. The 24-channel 12-bit ADC captures analog sensor inputs without an external multiplexer.","metaTitle":"NXP LPC1549JBD100551 ARM Cortex-M3 MCU, 72 MHz, 256 KB Flash","metaDescription":"NXP LPC1549JBD100551 32-bit ARM Cortex-M3 MCU, 72 MHz, 256 KB Flash, 36 KB RAM, 4 KB EEPROM, 76 I/O, CAN/USB/I2C/SPI/UART, 24×12-bit ADC, -40 to 105 °C, 100-LQFP.
