Product details

The NXP LPC1812JBD144551 is a 32-bit ARM Cortex-M3 single-core MCU from the LPC18xx series, clocked at 180 MHz with 512 KB Flash, 104 KB SRAM, and 16 KB EEPROM. The 180 MHz core gives you headroom for a single-cycle multiply and deterministic interrupt response in motor-control or CAN-based industrial networks. The 16 KB EEPROM is useful for calibration constants or boot parameters that survive a full erase of the Flash array — no external serial EEPROM needed for that data. The integrated motor-control PWM and DMA engine offload the core for time-critical commutation loops.

Package and footprint — 144-LQFP

The pitch needs a controlled solder profile and a clean stencil aperture — no special via-in-pad required.

Frequently asked questions

What is the core speed of the LPC1812JBD144551?

The ARM Cortex-M3 core runs at 180 MHz, which gives the part a 5.56 ns instruction-cycle time for single-cycle ALU operations.
