AVR128DB28/32/48/64 AVR DB Family Introduction The AVR128DB28/32/48/64 microcontrollers of the AVR DB family of microcontrollers are using the AVR CPU with hardware multiplier running at clock speeds up to 24 MHz. They come with 128 KB of Flash, 16 KB of SRAM, and 512 bytes of EEPROM. The microcontrollers are available in 28-, 32-, 48- and 64- pin packages. The AVR DB family uses the latest technologies from Microchip with a flexible and low-power architecture, including Event System, accurate analog subsystems, and advanced digital peripherals. AVR DB Family Overview The figure below shows the AVR DB 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.
