[volt-nuts] 3458A NVRAM (David C. Partridge)

[David C. Partridge]

 I contacted Conitec who have always been very helpful by all reports.

Sad to say they won't do the device support work for the FM18W08 on the Galep-4 without a charge (I guess this was bound to happen at some stage).

Ho-hum
Dave

Hello Dave,

I have experienced the same issue with my programmer and found out it must be the slow "Power-Up to First Access (tPU)" of 10ms from the FM1608B/FM16W08.
Older FM1608 were much faster (only 1µS).

see details
