They all seem software compatible, here is a list of ids I found in various datasheets: CY15B104Q-PZXI 7F7F7F7F7F7FC22C03 51-85075 8-pin PDIP Industrial CY15B104QN-50SXA 7F7F7F7F7F7FC22C40 001-85261 8-pin SOIC (EIAJ) Automotive CY15V104QN-50SXI 7F7F7F7F7F7FC22C04 002-18131 8-pin GQFN Industrial CY15B104QN-20LPXC 7F7F7F7F7F7FC22CA1 002-18131 8-pin GQFN Commercial CY15B104QN-20LPXI 7F7F7F7F7F7FC22C01 002-18131 8-pin GQFN Industrial CY15V104QN-20LPXC 7F7F7F7F7F7FC22CA5 002-18131 8-pin GQFN Commercial CY15V104QN-20LPXI 7F7F7F7F7F7FC22C05 002-18131 8-pin GQFN Industrial CY15B104QN-50LPXI 7F7F7F7F7F7FC22C00 002-18131 8-pin GQFN Industrial Sascha -- Pengutronix e.K. | | Steuerwalder Str. 21 | http://www.pengutronix.de/ | 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/
