hi All, I have a board using 4MB (i.e. 32Mbit) 5V (I measured the voltage to confirm it's not 3.3V) ROM chip in SOP-44 package (or maybe that's called 44PSOP, I am not really sure) : the markings are removed, all it says it's 32Mbit and I cannot tell the exact chip. So, I found the reference schematic and instead single 32Mbit chip it uses 2 x 27C160F chips:
So, my questions are:
1) considering that then the single 32MB chip needs to be compatible with that 2 x 27C160F setup, what could that single 32MBit chip be (including compatible chip models)?
2) is there EEPROM chip that is compatible with the chip ID-entified in 1), i.e. that allows easy erase and programming or all those compatible 5V 32Mbit chips are not electronically erasable?
Thank you!
[EDIT] just to add that I found "MX29L3211MC" as potential answer, but it's not 5V and 3.3V instead...
