I have attached datasheet for SST89E51RD2. I am reading data sheet for capacitor value but i didn't find it in datasheet.

How do you determine the value of the capacitor of the reset circuit for the SST89E51RD2 ?

The cap is for a power up delay.. Most new micros don't use one, but a 10uf cap wouldn't be a bad choice.. page 65 figure 31 shows that very circuit..
