pins that are externally pulled low will source current if the pull-up resistors are activated. The
Port D pins are tri-stated when a reset condition becomes active, even if the clock is not running.
The various special features of Port D are elaborated in “Alternate Functions of Port D” on page
70.
AVCC is the supply voltage pin for the A/D converter and a selection of I/O pins. This pin should
be externally connected to VCC even if the ADC is not used. If the ADC is used, it is recom-
mended this pin is connected to VCC through a low-pass filter, as described in “Analog Noise
Canceling Techniques” on page 163.
The following pins receive their supply voltage from AVCC: PC7, PC5:0 and (in 32-lead pack-
ages) PA1:0. All other I/O pins take their supply voltage from VCC.

3. About
3.1 Resources
www.datasheet4u.com
A comprehensive set of development tools, application notes and datasheets are available for
download at http://www.atmel.com/avr.
3.2 About Code Examples
This documentation contains simple code examples that briefly show how to use various parts of
the device. These code examples assume that the part specific header file is included before
compilation. Be aware that not all C compiler vendors include bit definitions in the header files
and interrupt handling in C is compiler dependent. Please confirm with the C compiler documen-
tation for more details.
For I/O Registers located in extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI”
instructions must be replaced with instructions that allow access to extended I/O. Typically
“LDS” and “STS” combined with “SBRS”, “SBRC”, “SBR”, and “CBR”.
3.3 Data Retention
Reliability Qualification results show that the projected data retention failure rate is much less
than 1 PPM over 20 years at 85°C or 100 years at 25°C.
3.4 Disclaimer
Typical values contained in this datasheet are based on simulations and characterization of
other AVR microcontrollers manufactured on the same process technology. Min and Max values
will be available after the device is characterized.
