PIC18F Q43 Microcontrollers

Microchip's series of 8-bit MCUs is optimized for responsive real-time control applications

Image of Microchip's PIC18F57Q43 MCU Family Applications Microchip's PIC18 Q43 family of microcontrollers (MCUs) is optimized for robust, responsive real-time control with integrated intelligent analog, configurable peripherals, and 5 V operation for increased noise immunity. The product family combines Microchip’s most popular, versatile, and easy to use core independent peripherals (CIP) with advanced interconnection capabilities for effortless hardware customization. The MCUs are equipped with direct memory access (DMA), configurable logic cells (CLC), 16-bit PWMs, a 12-bit ADC with computation (ADC²), and multiple communication interfaces. This combination simplifies the creation of customized hardware-based functions, improves system response, and reduces external components and code development time. The MCUs are well-suited for a wide range of real-time control applications including industrial control, consumer, automotive, motor control, capacitive touch sensing, and Internet of Things (IoT).
