For Burning 27FS512 EEPROM Chips in Burn 1, Burn 2, Or AutoProm Need to use Offsets!
If you are using TunerPro, look under the ‘Tools’ menu item and select the ‘Moates Prom I/O’ option. If you are using Flash n Burn, you should already be looking at this menu. In this menu you will need to do the following.
In the correct order:- Select the type of chip you’ll be programming from the drop-down menu. This will likely be either the AT29C256 or the 27SF512.
- Pick the ‘Load file to buffer’ option, and navigate to the file you want programmed on the chip. Select it, and it will be loaded to memory on the PC. Take note of the file size indicated in the message window. It will likely be one of four sizes: 4k, 16k, 32k, or 64k (kbytes).
- In the top right part of the window you will see the offset values that need to be changed. The file size along with the chip size will determine what offsets you need to use. (Flash n Burn usually automatically selects sane offsets based on your chip type and file size.) When you change the offset values, you will notice that other values will change automatically.
- It is critical that the correct values are filled in for all four boxes before programming the chip.
You may have to go back and re-enter values depending on the order you enter them. The following table summarizes what offsets you need to use depending on chip used and file size:
| File Size |
Chip |
Buffer Start -> End |
Chip Start -> End |
| 4k (4096) |
AT29C256 |
000000 -> 000FFF |
007000 -> 007FFF |
| 16k (16384) |
AT29C256 |
000000 -> 003FFF |
004000 -> 007FFF |
| 32k (32768) |
AT29C256 |
000000 -> 007FFF |
000000 -> 007FFF |
| 4k (4096) |
27SF512 |
000000 -> 000FFF |
00F000 -> 00FFFF |
| 16k (16384) |
27SF512 |
000000 -> 003FFF |
00C000 -> 00FFFF |
| 32k (32768) |
27SF512 |
000000 -> 007FFF |
008000 -> 00FFFF |
| 56k (57344) |
27SF512 |
000000 -> 00DFFF |
002000 -> 00FFFF |
| 64k (65536) |
27SF512 |
000000 -> 00FFFF |
000000 -> 00FFFF |
As you can see, the buffer (or file content) will be placed at the ‘end’ of the chip.
Once you have selected the proper chip, the proper file to use for the program content and the proper offsets you are ready to program the chip.
If using a 27SF512 chip, you must ‘Erase Chip’ first! This is not needed with the AT29C256. Go ahead and select the ‘Program Chip’ option. Follow this action with a ‘Verify’ command to make sure everything programmed correctly. You should get a ‘Success’ notice.
