Product details

The NXP LPC1815JBD144551 is a 32-bit ARM Cortex-M3 MCU from the LPC18xx series, clocked at 180 MHz with 768 KB Flash, 136 KB SRAM, and 16 KB EEPROM on-chip. It packs 83 GPIO, CANbus, motor-control PWM, and an 8-channel 10-bit ADC plus a 10-bit DAC — a fit for industrial drives, motor-control boards, and CAN-connected automation nodes that need a single-chip control core.

180 MHz on a Cortex-M3 core. The 136 KB SRAM supports a moderate control stack and CAN message buffers.

The motor-control PWM and the 8-channel 10-bit ADC are sized for a three-phase current-sense feedback loop — one ADC channel per phase plus a DC-link voltage. The 16 KB EEPROM on-chip saves an external serial EEPROM for parameter storage; just watch the endurance if you are writing calibration data every power cycle.

Frequently asked questions

What is the LPC1815JBD144551's core speed?
