ATmega3209/4809 – 48-pin
Data Sheet
megaAVR® 0-series
Introduction
The ATmega3208/3209/4808/4809 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-, 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.
The devices described here offer Flash sizes from 32 KB to 48 KB in a 48-pin package.
