ATtiny806/1606
tinyAVR
®
0-series
Introduction
The ATtiny806/1606 are members of the tinyAVR
®
0-series of microcontrollers, using the AVR
®
processor with hardware multiplier, running at up to 20 MHz, with 8/16 KB Flash, 512/1024 bytes of
SRAM, and 128/256 bytes of EEPROM in a 20-pin package. The tinyAVR
®
0-series uses the latest
technologies with a flexible, low-power architecture including Event System and SleepWalking, accurate
analog features, and Core Independent Peripherals.
Attention:  Automotive products are documented in separate data sheets.
