NXP LPC1519JBD100E

ARM® Cortex®-M372 МГц256 КБ (256К x 8)

Overview

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.

Features

• Internal 12 MHz RC oscillator cut to 1% accuracy for 25 C Tamb +85 C that can be utilized as a system clock if desired.

• Oscillator crystal with a frequency range of 1 to 25 MHz.

• Watchdog oscillator with a 503 kHz frequency range.

• Low-power 32 kHz RTC oscillator having outputs of 32 kHz, 1 kHz, and 1 Hz.

• System PLL enables CPU functioning at full speed without the use of a high-frequency crystal. The internal RC oscillator or the system oscillator can be used.

Applications

• Controlling the motors

• Inverters for solar power

• Motion is what propels us forward.

• Appliances for the home

• Power supplies that are digital

• Automation in construction and manufacturing

• Medical and industrial
