LPC81x & LPC83x 32-bit Arm® Cortex®-M0+ MCUs NXP Semiconductors LPC81x and LPC83x 32-bit Arm® Cortex®-M0+ MCUs are Arm® Cortex-M0+ based, low-cost 32-bit MCUs operating at CPU frequencies up to 30MHz. These MCUs balance versatile timing, connectivity, and analog peripherals while delivering it in a low pin count, easy-to-use package. The switch matrix allows designers to map pins accordingly to simplify component routing on a PCB. These MCUs include SCTimer, enabling users to generate a variety of timing or PWM waveforms without intervention from the CPU. To simplify serial communication requirements, the pattern match engine can be configured to generate interrupts from user-configurable Boolean operations on eight pins. Typical applications include 8/16-bit applications, motor control, consumer, fire and security applications, climate control, and lighting.
