The purpose of this document is to collect the various peripheral tech briefs (including
the AVR1000b Technical Brief), which describe how
to use C-code on new AVR® devices. These documents are particularly
useful for Microchip tinyAVR® 0- and 1-series, and megaAVR® 0-series devices.Figure . Block Diagram megaAVR® 0-series
Note:
The red boxes indicate the
peripherals with associated technical briefs in this document. In the online
version, these boxes are

The ATmega4809 microcontrollers of the megaAVR® 0-series are using
the AVR® processor with hardware multiplier, running at up to 20
MHz, with 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 package. 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.
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).
