5 Downward migration may require codemodification due to fewer available instances of some Peripherals . Horizontal migration to the left reduces the pin count and therefore also the available 1-1. tinyAVR 1-Series Overview32KB16KB8KB4KB2KB8142024 PinsFlashATtiny816 ATtiny817 ATtiny814 ATtiny417 ATtiny1616 ATtiny1617 ATtiny414 ATtiny416 ATtiny412 ATtiny214 ATtiny212 ATtiny1614 Devices with different Flash memory size typically also have different SRAM and name of a device of the series contains information as depicted below:Figure 1-2.
