Microchip AVR® DD & PIC18F56Q71 Microcontrollers

Broaden your portfolio now

Effortlessly meet the ever-changing requirements of modern electronics with Microchip’s portfolio of scalable 8-bit, 16-bit and 32-bit microcontrollers (MCUs), Digital Signal Controllers (DSCs) and microprocessors (MPUs). The MCUs feature flexible peripherals and functions, making it easy to create differentiated applications that set you apart from your competition.

Get started by using Microchip’s intuitive design environments and visual configuration tools, while their proven reference designs and professionally tested software libraries lower design risk.


The PIC18-Q71 broadens the PIC18 portfolio for high bandwidth, mixed signal and sensor applications with 2 integrated operational amplifiers, 12-bit differential ADC with Computation and Context Switching, 8/10-bit DACs, high-speed analog comparator, Analog Peripheral Manager and a 8-bit signal routing port to interconnect digital peripherals.

These 28-, 40- and 48-pin devices are also equipped with three 16-bit dual PWMs outputs, four Direct Memory Access channels, eight Configurable Logic Cells (CLCs) and two UARTS. The rich set of Core Independent Peripherals enable simple analog configurations and quick responses to system events in a variety of applications including lighting, motor control, medical, home automation, automotive and Internet of Things (IoT).



The AVR® DD family of microcontrollers feature the well-known AVR® CPU, now running at up to 24 MHz across the full supply voltage range of 1.8V to 5.5V. The family includes 16 KB, 32 KB, and 64 KB Flash variants in 14 to 32-pin package options. The AVR® DD family is designed to bring real-time control and multi-voltage operation to applications including industrial control, home appliance products, automotive, and Internet of Things (IoT).

The family uses the latest Core Independent Peripherals with low-power features and 5V operation for increased noise immunity. The Multi-Voltage I/O system allows safe bi-directional communication with systems running at a different voltage. The Event System, Configurable Custom Logic (CCL), along with intelligent analog peripherals like 12-bit differential ADC, Zero-Cross Detect (ZCD), 10-bit DAC together with the MVIO makes the AVR® DD family well suited for sensor applications, IoT end nodes, and other applications where signal conditioning or level-shifting is needed.
