ATtiny4313 Board Schematic Diagram

This schematic diagram shows the AVR ATtiny4313 circuit in it's minimal form, as it was built on the test board. The ATtiny4313 is using an external 16 MHz crystal. The ATtiny2313 is similar, but has 2k of flash instead of 4k, 128 bytes of EEPROM, instead of 256, and 128 bytes of SRAM instead of 256 bytes.

Projects featuring the ATtiny4313
