Typical values contained in this data sheet are based on simulations and characterization of
actual Atmel ATtiny24/44/84 AVR microcontrollers manufactured on the typical process tech-
nology. Applicable Automotive Min. and Max. values will be available after devices
representative of the whole process excursion (corner run) have been characterized.
