Optimized Performance and Versatility for Hardware Customization

The PIC18-Q43 series of MCUs 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).

System Features

Improved System Performance

Direct Memory Access (DMA)

The PIC18-Q43 family is equipped with six Direct Memory Access (DMA) controllers for data transfers between all memory spaces and peripherals independent of the CPU, thereby enhancing system performance and improving power consumption.

Hardware Customization

Custom Logic

The on-chip Custom Logic peripherals on PIC and AVR MCUs eliminate the need for external components and complicated design work. With these on-chip peripherals, you can apply customized logic without physically expanding your application’s size.

Integrated Analog

12-bit ADCC, 8-bit DAC, ZCD

The on-chip integrated analog peripherals include Zero Cross Detect (ZCD), comparators, a 8-bit Digital-to-Analog Converter (DAC) and a 12-bit ADCC that automates Capacitive Voltage Divider (CVD) techniques for implementing advanced touch sensing, averaging, filtering, oversampling and automatic threshold comparison.

Power-Conserving Functionality

IDLE, DOZE, Peripheral Module Disable (PMD)

IDLE and DOZE low-power modes allow you to optimize your application for device performance and power consumption. The Peripheral Module Disable (PMD) allows unused peripherals to be turned off individually, further reducing power consumption.
