Hi ! Upto now I had no need to serach for replacement chips and I tried it for the first time. I tried with "NetComponents" link from www.chipdir.nl page and my browser did not accept cookies (which is odd, I checked the settings, all was OK). I don't know how to search more. I discarded ftz since these chips are very likely to be obsolete.
Here's the info : Type : ROM Manufacturer : Macronix Site : http://www.macronix.com Datasheet : http://www.fulcrum.ru/Documents/CDROMs/MACRONIX/memPdf/maskrom/23c2100.pdf Memory : 2M-BIT [256K x 8/128K x 16] CMOS MASK ROM Marking : MX23C2100 Pinout : NC 1 40 A8 A7 2 39 A9 A6 3 38 A10 5 4 37 A11 4 5 36 A12 3 6 35 A13 2 7 34 A14 1 8 33 A15 0 9 32 A16 ~CE 10 31 ~BYTE VSS 11 30 VSS ~OE 12 29 Q15/A-1 Q0 13 28 Q7 Q8 14 27 Q14 Q1 15 26 Q6 Q9 16 25 Q13 Q2 17 24 Q5 Q10 18 23 Q12 Q3 19 22 Q4 Q11 20 21 VCC Are there any EEPROM/FlashROM chips compatible to this type ? Even the ones with different pin layout are OK (I'll just make a PCB to re-route the connections), as long as they have the same functioning. BTW: If anyone gives Me the lesson about doing a search myself, I won't mind. But then I'm a just a worker on a '83 milling machine. Next problem : either I'm browser-blind or I or could not find the official sharp website (while searching, I even stumbled upon a medical company !?). I need this URL to find a datasheet for LH5320H4 (it performs the same function as the above MX23C2100 chip). I need data on this one as well to make sure about pin-layout and maybe speedup the search for compatible ROM chips.
