The AVR® DA family of microcontrollers are
using AVR CPU with hardware multiplier, running at up to 24 MHz, with 32/64/128 KB of
Flash sizes, 4/8/16 KB of SRAM, and 512B 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 and Sleepwalking, accurate analog features, and
advanced digital peripherals.Figure 1-1. Overview of AVR® DA Family Microcontrollers
Figure 1-1 shows the AVR DA family microcontrollers with
different pin counts and flash memory sizes. The parts with different flash memory sizes
typically also have different RAM and EEPROM.
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.
From the available microcontrollers of AVR DA family, the 48-pin and 64-pin devices
are relevant for this application note, as these devices are equipped with two and
three instances of ZCD peripheral respectively.
Note: The 48-pin and 64-pin devices of AVR DB family are also relevant for this application
note, as these devices are equipped with two and three instances of ZCD peripheral
respectively.
