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. For this reason, the pins PB[5:0] and PC[7:6] must be disabled (INPUT_DISABLE)
or enable pull-ups (PULLUPEN).
megaAVR
®
0-series Overview
The figure below shows the megaAVR
®
0-series devices, laying out pin count variants and memory sizes:
• Vertical migration is possible without code modification, as these devices are fully pin and feature compatible
• Horizontal migration to the left reduces the pin count and, therefore, the available features
