Footnote# Footnote 0 B/2004 1 Use "Special Device Functions" menu to set protection of individual Sector/Block of the device. 2 Programming of a protected device is not allowed. Attempting to program a protected device may produce a programming error. 3 Chip erase option should be ON before programming a protected device. 4 The Sprint user memory map is same as device memory map. 5 The ID locations are located at buffer address [4000h-4007h]. The Configuration word is located at buffer address [400Eh]. 6 Both the Configuration words and device ID bytes can be set from "Special Device Functions" menu or from the above said addresses in the data file. 7 The checksum is calculated by using the special procedure given in device datasheet or as per device manufacturer specifications. 8 Check 2nd line on device (FPO-code).If last character is 'A' select (D)-type device. 9 Flash memory is located at buffer address [0h-FFFFh], and is accessed as byte wide data. 10 OSD Flash memory is located at buffer address [10000h-17FFFh], and is accessed as word wide in Big Endien data format. 11 When using the device in word wide data access, use the data file of Big-Endian data format. 12 The Boot sector protection is OTP, and once protected it can not be unprotected. 13 Sprint memory map is supported for a file which is generated by Cypress design tools. 14 The buffer address [100000h-10003Fh] are security bytes, embedded in data file. 15 Security bytes can be erased/programmed, but not read/verified. 16 The buffer address from [200000h-200001h], contains two bytes of checksum information embedded in the data file. 17 The Code array of 8 kBbyte size is located at buffer address [0000h-1FFFh]. 18 The Data array of 2 kBbyte size is located at buffer address [2000h-27FFh]. 19 You can program different security modes of the device by proper setting through "Special Device Functions" menu. 20 The device SPF (Serial Programming Fuse) programming can be enabled through option available under "Special Device Functions" menu. 21 Buffer address 0000h contains Flash Option Bits. Once you program the Flash Read Protect (FRP) option bit (Bit 2), no further operations can be performed on the device. 22 Buffer address 0001h is reserved for future use and must contain Blank data [FFh] in it. 23 The device has Read Protection feature and can be set through "Special Device Functions" menu. 24 Pages 5,6 and 7 of the device [F8A0h-F8FFh] are reserved pages, no operations will be done on these reserve pages. 25 These devices have programmable reset polarity. Use "Special Device Functions" menu to set the reset polarity. 26 The Write Protect Register is programmed with the address value of the first word that is to be protected. All address values equal to or greater than the value contained in the Protect Register will be protected from further writes. 27 Use "Special Device Functions" menu to set Protect Register value. 28 To secure the content of the Protect Register from any future writes permanently, set this option to 'Disable' in "Special Device Functions" menu. 29 To check it out, first perform Device Read operation, then check the option under "Special Device Functions" menu. 30 Use "Special Device Functions" menu to enable the security feature of the device. 31 The ID locations are located at buffer address [200000h-200007h]. The Configuration bytes are located at buffer addresses [300000h-30000Dh]. 32 The device has 256 bytes of Data Memory(EEPROM) located at buffer address [F00000h-F000FFh]. 33 The device has 1024 bytes of Data Memory(EEPROM) located at buffer address [F00000h-F003FFh]. 34 DUMMY.
