Product details

The NXP LPC1823JBD144551 is a 32-bit ARM Cortex-M3 MCU from the LPC18xx series, clocked at 180 MHz. It carries 512 KB of Flash program memory, 104 KB of RAM, and 16 KB of EEPROM on-chip, with a peripheral set that includes CAN, USB OTG, motor control PWM, and multiple serial interfaces. Rated for -40°C to 105°C operation, it fits industrial control, motor drive, and embedded connectivity applications where a single-core M3 with integrated EEPROM and CAN bus is needed.

The LPC1823JBD144551 includes 512 KB Flash and 104 KB RAM. The on-chip 16 KB EEPROM eliminates an external serial EEPROM for calibration data.

For BOM planning, the active status reduces supply risk compared to NRND or EOL parts.

Frequently asked questions

What is the closest pin-compatible alternative to LPC1823JBD144551?

Within the LPC18xx series, the LPC1833JBD144551 is pin-compatible and offers 1 MB Flash and 136 KB RAM, but the EEPROM size and peripheral set are identical. No direct second-source from another manufacturer is listed.

What is the core speed of LPC1823JBD144551?

The LPC1823JBD144551 runs at 180 MHz, which is the maximum core clock for this ARM Cortex-M3 device.

What compliance documentation does NXP provide for LPC1823JBD144551?

NXP provides RoHS and REACH compliance documentation for this part. The 144-LQFP package is lead-free and RoHS-compliant per standard NXP declarations.
