Bog'liq habibulloAVR mikrokontrollerlari periferiya qurilmalari: ichki kalibrovkalangan RC-generator (chastotasi 1, 2, 4, 8 MHz, ba’zi modellarda ATtiny — 4,8, 6.4, 9.6 MHz va 128 kHz). Ichki flesh-xotira 256 KBaytgacha. JTAG (TMS, TDI, TDO, va TCK) kiritish-chiqarish portlariga multipleksorlash signallari. Ichki ma’lumotlar uchun EEPROM-xotira 4 KB gacha (ATmega/ATxmega)/512 bayt (ATtiny) (100 000 marta qayta yozish). Ichki xotira SRAM 32 KB gacha (ATxmega)/16 Kb(ATmega)/1 Kb(ATtiny) vaqtinchalik 2 taktli murojaat. Tashqi xotira hajmi 64 KB gacha (ATmega8515, ATmega162, ATmega640, ATmega641, ATmega1280, ATmega1281, ATmega2560, ATmega256). 8, 16 bit razryadli taymerlar. 8-, 9-, 10-, 16-bitli ШИM-modulyator (PWM). Analog komparatorlar. differentsial kirishli ARO (ADC), razryadliligi 8(ATtiny)/10(ATtiny/ATmega)/12(ATxmega) bit: ARO’ oldidagi dasturlanuvchi kuchaytirish koeffitsienti 1, 10 va 200 (differentsial rejimda); Kuchlanish manbalari, tashqi kuchlanish manbalari yoki ichki tayanch kuchlanishlari 2,56 V / 1,1 V (bazi ATtiny modellarida) tayanch kuchlanishi sifatida olinishi mumkin. Quyidagilarni oz ichiga oluvchi turli xil ketma-ket interfeyslar: UART/USART -universal sinxron/asinxron priyomoperedatchik; Serial Peripheral Interface (SPI) -sinxron ketma-ket port. USB interfeysi AT90USBxxxx seriya uchun. CAN interfeysi AT90CANxxx seriya uchun. LCD interfeysi ATmega169 va ATmega329 seriyalari uchun. ATtiny25, ATtiny45, ATtiny85 seriyalari uchun harorat datchigi. Izoh: hamma periferiya qurilmalarini ham dastur orqali ishga tushirib bolmaydi. fuses registridagi bit faqat programmator yordamida ozgartirilishi mumkin.
