LPC1517JBD48E Product Details

NXP LPC1500 Motor Control ARM Cortex-M3 MCUs are optimized for fast, easy, high-precision motor control of sensored/sensorless brushless DC (BLDC) and permanent magnet synchronous motors (PMSM). LPC1500 is ideal for large consumer appliances, HVAC, Elevator/escalator control, and industrial pump and generator control. LPC1500 supports two motors through 2 12-bit, 12-channel, 2Msps ADCs and a quadrature encoder interface. Precise PWM generation allows for efficient motor drive. Advanced analog subsystems and timing is ideal for PID control loops. CAN module sinplifies industrial connectivity and USB allows easy field upgrades. Free FOC motor control firmware is available, and GUI based tools streamline any repetitive tuning and calibration.
