Microchip PIC18-Q43 Family

Product Overview

The PIC18-Q43 product family combines our most popular, versatile and easy-to-use Core Independent Peripherals (CIPs) with advanced interconnection capabilities for effortless hardware customization. These microcontrollers (MCUs) are equipped with Direct Memory Access (DMA), Configurable Logic Cells (CLCs), 16-bit PWMs, a 12-bit Analog-to-Digital Converter with Computation (ADCC) and multiple communication interfaces. This combination of peripherals simplifies the creation of customized hardware-based functions, improves system response and reduces the number of external components and code development time. They 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).
