AVR32DD20-E/REB

The AVR32/16DD14/20 microcontrollers of the AVR DD Family of microcontrollers are using the AVR CPU with hardware multiplier running at clock speeds up to 24 MHz, with up to 32 KB of Flash, up to 4 KB of SRAM, and 256 bytes of EEPROM. The microcontrollers are available in 14- or 20-pin packages. The AVR DD Family uses the latest technologies from Microchip Technology, with a flexible and low-power architecture, including the Event System, intelligent analog features, and advanced digital peripherals.
