If you worked with the LP2052 you would have read about it in the datasheet. The user signature row is 64 bytes of programmable data area. In the LP2052 it has 32 bytes. Good to store version information, configuration or any other data you wish. The user signature row is readable even if the chip is locked.
To program the US Row, you must first program the fuse which enables programming of the user signature row. Of course, I haven't found a programmer that will program it yet, aside from writing some of my own routines to do it. |

| Have you carefully read this document? | 01/01/70 00:00 | |
| yes, got it, read it | 01/01/70 00:00 | |
| What happens if you erase the chip? | 01/01/70 00:00 | |
