Complete automotive EEPROM marking reference, with the original workshop list, the additional 93 / 24 / 25-series notes and the MCU mask-code appendix. All original entries are retained, including conflicting or uncertain ones.
The supplied workshop list records 4G04 / 24C04, H160 / 95160 and C46 / 93C46. Use these entries to find the corresponding original reference, then compare the complete marking on your component.
All reference rows are shown. The original series notes remain visible below.

Additional 93 / 24 / 25-series notes
English translation of the supplied workshop notes. Model codes and correspondence entries are retained as written.

93LC46 93LC56 93LC66 93LC76 93LC86
Note: Parts with “L” are low-voltage devices, with an operating voltage of 1.8V–5.5V; parts without “L” operate at 4.5V–5.5V.
Parts with “L” can replace parts without “L”; parts without “L” cannot replace parts with “L”.

MCU mask-code appendix from the original document
This appendix includes HC05/HC08/HC11/HC12-related names and the source heading “9S12”. It is preserved in full; that heading does not establish that every listed device belongs to the 9S12 family. Original “MSE” spellings and question marks have not been silently corrected.
