Hello Everyone! Please can anyone give me a suggestion what can be cause of strange problem with starting STC12C5A60S2 ?
Board on STC12C5A60S2 wouldn't start until I touch oscillator pins with unconnected! multimeter wires, seems like capacitance of wires, ~some pf, make a deal.
Recently I tried different oscillators orignal-4mh, 6, 8, 10, 12 mhz, different capacitors 1, 10, 22, 47 pf, nothing working. Power line of a board is fine.
Thanks.
