ATtiny406 AVR® Microcontrollers

Microchip Technology ATtiny406 AVR® Microcontrollers are capable of running at up to 20MHz with up to 4KB Flash, 256bytes of SRAM, and 128 bytes of EEPROM. These MCUs use the low-power AVR RSIC architecture and the latest technologies, including Event System and SleepWalking. The ATtiny406 MCUs feature core independent peripherals, accurate analog features, multiple clock options, Single Pin Unified Program Debug Interface (UPDI), and three sleep modes. These MCUs operate at -40°C to +125°C temperature range and are available in a 20-pin package.
