Microcontrollers run at clock speeds up to 24MHz

These microcontrollers feature the AVR CPU with a hardware multiplier running at clock speeds up to 24 MHz.

They offer up to 64 KB Flash, up to 8 KB SRAM, and 256 bytes of EEPROM. The AVR DU MCUs come in 14-pin, 20-pin, 28-pin, and 32-pin package options.

They support crystal-less USB operation and include an optional internal 3.3V voltage regulator. 

The devices use Core Independent Peripherals (CIPs) and USB 2.0, along with an Event System and Configurable Custom Logic (CCL), to provide efficient data transfer and noise immunity for industrial applications.

These MCUs offer seamless USB updates and TTL-compatible pins for secure, uninterrupted functionality.

Their USB stack supports multiple device classes and powers versatile applications like charging and system upgrades.

The AVR DU family of MCUs complies with the IEC 61508 and ISO 26262 functional safety standards, which makes them an excellent choice for safety-critical industrial and automotive applications.
