Microchip Technology ATmega3209 Microcontrollers

Microchip Technology ATmega3209 Microcontrollers megaAVR^® 0-series uses the AVR^® processor with hardware multiplier and runs up to 20MHz. These MCUs include memories of 6KB SRAM, 256bytes of EEPROM, and a wide range of flash size up to 48KB. The ATmega3209 MCUs use the latest technology with a flexible and low-power architecture, including Event System and SleepWalking, accurate analog features, and advanced peripherals.
