AVR64DD32 AVR® CPU

Microchip's AVR DD family of microcontrollers features the well-known AVR CPU, now running at up to 24 MHz across the full supply voltage range of 1.8 V to 5.5 V. The family includes 16 KB, 32 KB, and 64 KB Flash variants in 14-pin 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 the Internet of Things (IoT).

The family uses the latest core independent peripherals with low-power features and 5 V operation for increased noise immunity. The multi-voltage I/O system allows safe bidirectional communication with systems running at a different voltage. The event system, Configurable Custom Logic (CCL), along with intelligent analog peripherals like 12-bit differential analog-to-digital converter (ADC), zero cross detect (ZCD), 10-bit digital-to-analog converter (DAC) together with the Multi-Voltage I/O (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.

The AVR64DD32 comes in TQFP and VQFN package options running at up to 24 MHz and with 64 KB Flash, 8 KB SRAM, and 256 B of EEPROM. The AVR64DD32 product supports four multi-voltage I/O channels capable of bidirectional communication with external devices running at a higher or lower voltage than the MCU itself. The MVIO system makes the AVR DD a perfect device for board control, sensor applications, IoT end nodes, and other size-constrained applications and for sensor fusion in larger systems.

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.
