NEC uPD6258 serial EEPROM datasheet
(1/1)
Gyorgy Albert:
Hi forum members,

I am looking desperately for the datasheet of an older 3 wire serial EEPROM made by NEC, uPD6258. It is a SOP8 3 wire device (similar to the Microwire interface) with 8 kbit capacity. Maybe I am lucky, and someone can help with the complete datasheet. It is in a pre-2K generation measurement instrument, and holds the calibration coefficients, which I would like to backup. All what I found are two lines in the 1995 NEC Semiconductor Selection Guide (including the uPD6257, the smaller 4kbit brother).

Thanks in advance,
Gyorgy (George)

some references here  but  programming wise ?

you have to check in many programmers their supported devices list ???
