ATmega4809 - Microcontrollers

Download the ATmega4809 datasheet PDF. This datasheet also covers the ATmega4808 variant, as both devices belong to the same microcontrollers family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • and advanced peripherals. The devices described in this data sheet offer 48 KB in a 28/32/40/48-pin package. Important:  The 40-pin version of the ATmega4809 is using the die of the 48-pin ATmega4809 but offers fewer connected pads. For this reason, the pins PB[5:0] and PC[7:6] must be disabled (INPUT_DISABLE) or enable pull-ups (.

ATmega4808/4809 ATmega4808/4809 Data Sheet Introduction The ATmega4808/4809 microcontrollers are part of the megaAVR® 0-series, which uses the AVR® processor with hardware multiplier running at up to 20 MHz, and offers a wide range of Flash sizes up to 48 KB, up to 6 KB of SRAM, and 256 bytes of EEPROM in 28-, 32-, 40-, or 48-pin packages. The series uses the latest technologies from Microchip with a flexible and low-power architecture, including Event System and SleepWalking, accurate analog features, and advanced peripherals. The devices described in this data sheet offer 48 KB in a 28/32/40/48-pin package. Important:  The 40-pin version of the ATmega4809 is using the die of the 48-pin ATmega4809 but offers fewer connected pads.
