Hi ! I was looking around for the CMOS mask ROM (later I found it's name) marked MX 23C2100. I looked around Macronix site and found no datasheet for it. I seems it's production is discountined. As I heavily depend on it's proper functioning (it is a OS ROM) and my computer is not getting any younger by the day, I thought it would be a good idea to have a backup of it.
But, since I found no other references on the net for 23C2100, I don't know which (newer) part can replace it. I'm willing to even do some pin-shuffling with small adaptor-PCB, as long as it can function within specs of the original (mem size and organization, A0-A16, Q0-Q15, OE and CE pins). Also, I'm not clear on how does the ~BYTE pin work ? Does the mem organization work as bytes when ~BYTE is low-active or high-inactive ? The pdf I gave URL of in previous post has an error on page 2, where both tables show "~BYTE=VSS" and that's the point of confusion. The only real candidate for this is MX 23C4100 (found on Macronix site) that seems to be an ideal drop-in replacement, but that isn't EEPROM or FlashROM type. I need EEPROM or FlashROM since : 1. It is easier to find 2. If I make a mistake it won't be thrown away, just re-programmed again Any help is appreciated. PS : Feel free to warn Me what does "mask ROM" really means. :-) Regards -- Boris -- Author: Boris Ivic INET: [EMAIL PROTECTED] Fat City Network Services -- (858) 538-5051 FAX: (858) 538-5051 San Diego, California -- Public Internet access / Mailing Lists -------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB CHIPDIR-L (or the name of mailing list you want to be removed from).
