Reading TSOP48 mask ROM mrom, tsop48

raybellis

I have a Macronix 5V Mask ROM that I need to read which has a non-standard pinout, which as far as I can tell is very similar to this for the Sharp LH533 MROM series.

Can anyone advise a supported chip that I can select that will allow me to read its data?

This chip is same as MX23C3211, choose MX23C3211 to read.

Thanks! That worked :D

Actually it doesn't work quite right, because the MX23C3211 is only 4MB, and the chips I have are 8MB :'(

I believe I need MX23C6410 support, with the only difference being that pin 12 is A21 instead of VSS.
