 		 #91236 - 3.3 Volt EPROMs in a 5 Volt System
Hi, i'm building a 8052 system with a 5 volt supply. The AMD 8052s I have are all specified to run at 5 volts like usual, but then I have these unusual M27V512 EPROM memory chips from SGS Thomson that run at 3.3 volts. I have not yet built the circuitry, so I'm wondering if the EPROMs I have (M27V512) are able to operate in read mode under a supply voltage of 5 volts, and that I can integrate it into my system just like a M27C512 (5 volt 32kbyte eprom). The specifications do state that the M27V512 will operate within a vcc range of -2 to 7 volts, but I dunno if it'll be likely that i'll be able to read data off the ERPOM with vcc=5v. I think when vcc=5volts, the EPROM is in verification mode, and I don't think it's the same as read mode.

thanks!
