An additional 256 bytes of EEPROM (256 x 8) holds calibration constants and configuration parameters that survive power cycles. ## On-chip analog and serial connectivity reduce external parts Thirteen 12-bit SAR ADC channels (A/D 13x12b SAR) and one 10-bit DAC (D/A 1x10b) are integrated, so a temperature sensor, potentiometer, or current-sense amplifier can connect directly without an external converter. The peripheral set includes Brown-out Detect/Reset, POR, PWM, and WDT — all standard for reliable standalone operation. The oscillator can be driven from an external crystal or the internal RC, saving a component when board area is tight.","metaTitle":"Microchip AVR64DD20-I/SO AVR MCU, 24MHz, 64KB Flash, 20-SOIC","metaDescription":"Microchip AVR64DD20-I/SO 8-bit AVR MCU, 24MHz core, 64KB Flash, 8KB RAM, 20-SOIC package, -40°C to 85°C.

The AVR64DD20-I/SO is the 64 KB / 20-pin SOIC variant; if you need more I/O or a smaller package, the AVR32DD28T-I/SS is a valid cross-shop candidate, though memory and pin count differ."},{"question":"Will AVR64DD20-I/SO work with Arduino IDE?","answer":"The AVR® DD series is supported in Microchip's MPLAB X IDE and Studio 7. Arduino IDE support depends on third-party board packages; check the Arduino community for AVR DD core availability. The part itself is an 8-bit AVR core, so it is architecturally compatible with the Arduino ecosystem, but official toolchain support is through Microchip's tools."},{"question":"Is AVR64DD20-I/SO RoHS compliant?","answer":"Yes, the part is ROHS3 Compliant, meeting the latest EU RoHS directive without exemptions."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/AVR64DD20-I-SO","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/AVR64DD20-I-SO when reusing this data.
