Posted - 11/12/2004 : 07:38:41 I try to burn a 2732A chip. I can read similar chips, I can verify that the new is blank, but I can't write to the chip. It says programming chip(the red status bar increases), but the chip is still blank. I have a 12 V power supply and have set all the jumpers according to the software(I think). I have tried another PC, but same problem. Any Ideas? THanks

Posted - 11/13/2004 : 23:22:23 Most likely your Vpp setting is not correct. Also, the Vcc you need set to 6.2V.
Most of 2732 uses 25V Vpp, but some may use 21V or 12V. Confirm your chips Vpp from the datasheet.
