AVR-DA
Product Brief
Introduction
The AVR-DA family of microcontrollers is using the AVR® CPU with hardware multiplier, running at up to 24 MHz, with
32/64/128 KB of Flash, 4/8/16 KB of SRAM, and 512 bytes of EEPROM in 28-, 32-, 48-or 64-pin packages. The
family uses the latest technologies from Microchip with a flexible and low-power architecture including Event System,
accurate analog features, advanced digital peripherals and Peripheral Touch Controller (PTC). Features
