Hello,
I can't find anywhere how to connect ISP on an Atmega T44A chip, I would like to use an arduino nano for programming, but being an SMD I have to finish studying the PCB and put the 6 pins for ISP programming.
does anyone have a schematic?
thank you
I do not quite understand your problem.
For ISP you need: SCK -> PA4; MISO->PA5; MOSI->PA6 and RESET->PB3. That will be the same for both packages.

more power?
More power for what?
Maybe you are referring to the VCC & GND pins that you have seen on the 6-pin ISP headers?

yees
Connect the 4 signal pins to the 6-pin ISP header as @Willem43 says in post #2. Then route VCC and GND to the 2 remaining pins on the header.
Or am I missing something?
yes, I knew that too but I wanted to be sure, where they were on the chip that I use square smd
The datasheet will identify the pinout for the specific package type you have.
