AVR128DA28/32/48/64 AVR DA Family Introduction The AVR128DA28/32/48/64 microcontrollers of the AVR DA family are using the AVR CPU with hardware multiplier, running at up to 24 MHz, with 128 KB of Flash, 16 KB of SRAM, and 512B of EEPROM in 28-, 32-, 48- or 64-pin packages. The AVR DA family uses the latest technologies from Microchip Technology, with a flexible and low-power architecture including Event System, intelligent analog features, advanced digital peripherals and Peripheral Touch Controller (PTC). AVR DA Family Overview The figure below shows the AVR DA devices, laying out pin count variants and memory sizes: Vertical migration is possible without code modification, as these devices are fully pin and feature compatible Horizontal migration to the left reduces the pin count, and therefore, the available features Figure 1.AVR DA Family Overview Devices described in this data sheet Devices described in other data sheets Flash 128 KB AVR128DA28 AVR128DA32 AVR128DA48 AVR128DA64 64 KB AVR64DA28 AVR64DA32 AVR64DA48 AVR64DA64 AVR32DA28 32 KB AVR32DA32 AVR32DA48 Pins 28 32 48 64 Devices with different Flash memory sizes typically also have different SRAM.
