Procurement Notes
Verify that the ordering suffix 'R' corresponds to the tape and reel packaging format as defined in the manufacturer's documentation. Confirm the specific speed grade and supply voltage requirements align with the intended application environment before procurement.
Selection Notes
Select this component when 4K bytes of program memory are required compared to the 2K byte variant. Ensure the design accommodates the 20-pad MLF package dimensions and thermal requirements. Verify compatibility with existing development tools supporting the AVR instruction set.
Part Context
This part belongs to the ATtiny family of 8-bit microcontrollers based on the AVR enhanced RISC architecture. It shares functional similarities with the ATtiny2313A but provides double the memory capacity. The device is manufactured using high-density non-volatile memory technology.
