Microchip Technology AVR64DA48
The AVR64DA28/32/48/64 microcontrollers of the AVR® DA family are using the AVR CPU with hardware multiplier, running at up to 24 MHz, with 64 KB of Flash, 8 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 lowpower architecture including Event System, intelligent analog features, advanced digital peripherals and Peripheral Touch Controller (PTC). The name of a device in the AVR® DA family is decoded as follows: Figure 2.FEATURES
