Reading, erasing and writing SPI, I2C and Microwire EEPROMs with ABPROG (ZN031 / ZN035)

Strumenti Interface Classic Flashing / Programming Medium ⏱ 15-30 min 12 steps

This is the ABPROG's bread-and-butter function: reading, erasing, programming and verifying the serial memories in automotive modules. You use it to save a dump before modifying it, to clone a module or to rewrite an EEPROM after the job.

Hardware / cables

  • AVDI
  • ZN045 programmatore ABPROG
  • ZN031 adattatore EEPROM/BCM
  • ZN035 socket EEPROM 8 pin
  • CB101 prolunga
⚠ WarningBefore erasing or programming any memory, read the original dump and save it to the PC with "Save": the "Erase" function wipes the chip content and without a backup the module is beyond recovery. Use "Verify" after every write to confirm the chip content matches what's in the hex editor.

Procedure

  1. Connect the ZN045 to the AVDI and the AVDI to the PC, then plug the right adapter into the DB25 on the ZN045: ZN031 (EEPROM/BCM) for memories still soldered to the board, ZN035 (EEPROM socket) for desoldered 8-pin memories.
  2. Open "ABProg" > "Upgraded" to get to the programmer's main screen.
  3. Press "Select": the list of all supported devices opens. Pick the family and the exact chip you have in front of you.
  4. For SPI EEPROMs the software supports ST M35080VP / M35080V6, ST D080D0WQ, D160D0WQ, ST M95010, M95020, M95040, M95080, M95160, M95320, M95640, M95128, M95256 and M95P08.
  5. For I2C EEPROMs, 24C01, 24C02, 24C08, 24C16, 24C32, 24C64, 24C128, 24C256, 24C512 and 24C1024 are supported.
  6. For Microwire, 93C46, 93C56, 93C66, 93C76 and 93C86 are supported, each in both 8-bit and 16-bit organisation: pick the wrong organisation and the dump comes out unreadable or byte-swapped, so check it on the module.
  7. Press "Diagrams": if a connection diagram exists for the selected device, the software shows it. Wire the adapter leads according to that diagram.
  8. Press "Read" to read the memory. The content appears in the hex editor.
  9. Press "Save" and save the original dump to the PC as a backup straight away, before you touch anything.
  10. If you need to load a ready file (a modified dump or the donor module's dump) use "Load" to bring it into the hex editor; with "Find/Replace" you can search for a hex or UTF-8 pattern within the editor content.
  11. If the chip requires it press "Erase" to wipe it, then "Program" to write the hex editor content to the chip.
  12. Finish with "Verify": the software compares the chip memory against the hex editor content and tells you whether the write went through.
