ATtiny202/204/402/404/406
Automotive
tinyAVR
®
0-series
Introduction
The ATtiny202/204/402/404/406 Automotive are members of the tinyAVR
®
0-series of microcontrollers, using the
AVR
®
processor with hardware multiplier, running at up to 16 MHz, with 2/4 KB Flash, 128/256 bytes of SRAM, and
64/128 bytes of EEPROM in an 8-, 14-, 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.
