ATtiny202/204/402/404/406
tinyAVR
®
0-series
Introduction
The ATtiny202/204/402/404/406 are members of the tinyAVR
®
0-series of microcontrollers, using the AVR
®
processor with hardware multiplier, running at up to 20 MHz, with 2/4 KB Flash, 128/256 bytes of SRAM, and 64/128
bytes of EEPROM in a 8-, 14-, or 20-pin package. The tinyAVR
®
0-series uses the latest technologies with a flexible,
low-power architecture, including Event System, accurate analog features, and Core Independent Peripherals (CIPs).
