thank you Eric for answer.
I tried max232 without transistors. Everything works fine with old chips. I measure the supply current(max232 not connected). 8 ma for old chips after "touchless" and restart(when they are ready for ISP). And 0.2 ma for the new ones. It looks like they are near power-down mode. (i test 5 old chips in 5 boards and 15 new chips on the same boards). |
