Microchip AVR64DD32 Family of Microcontrollers (MCUs)

Features the well-known AVR® CPU

Microchip’s 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 microcontrollers include 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.

This product is recommended for safety-critical applications targeting industrial and automotive products (IEC 61508 and ISO 26262). Necessary documentation, such as the FMEDA report and a Safety Manual, can be provided on request. Certified development tools are also available for this product.
