Product 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 offer 48 KB in a 28/32/40/48-pin package.
