Справочная информация:
Буква V в названии микросхемы означает пониженное напряжение питания;
Буква A - микросхема имеет расширенный диапазон питания от 1.8 до 5.5 Вольт;
Буква P - PicoPower - пониженное потребление;
Для уточнения названия столбца (например, если смотреть таблицу далеко от шапки) нужно просто подвести курсор к ячейке - всплывет подсказка.
Таблица находится в постоянной доработке. О замечаниях и неточностях пишите Moriam ˆˆ
Об atmega: все из нижеперечисленных микросхем имеют сторожевой таймер (watchdog), систему контроля питания brown-out detection, RC-генератор и имеют возможность внутрисхемного программирования
