7810C–AVR–10/12
Atmel ATmega328P [Preliminary]
1.1.7
AV
CC
AV
CC is the supply voltage pin for the A/D Converter, PC3:0, and ADC7:6. It should be externally
connected to V
CC, even if the ADC is not used. If the ADC is used, it should be connected to VCC
through a low-pass filter. Note that PC6..4 use digital supply voltage, V
CC.
1.1.8
AREF
AREF is the analog reference pin for the A/D Converter.
1.1.9
ADC7:6 (TQFP and QFN/MLF Package Only)
In the TQFP and QFN/MLF package, ADC7:6 serve as analog inputs to the A/D converter.
These pins are powered from the analog supply and serve as 10-bit ADC channels.
1.2
Disclaimer
Typical values contained in this datasheet are based on simulations and characterization of
actual ATmega328P AVR microcontrollers manufactured on the typical process technology.
Automotive Min and Max values are based on characterization of actual ATmega328P AVR
microcontrollers manufactured on the whole process excursion (corner run).
1.3
Automotive Quality Grade
The ATmega328P have been developed and manufactured according to the most
stringent requirements of the international standard ISO-TS-16949. This data sheet contains
limit values extracted from the results of extensive characterization (Temperature and Voltage).
The quality and reliability of the ATmega328P have been verified during regular product
qualification as per AEC-Q100 grade 1.
As indicated in the ordering information paragraph, the products are available in only one tem-
perature grade.
