Indy NVRAMs

Unread postby cris_adder » Sun Feb 19, 2012 1:55 am

Just came across these New Old Stock (NOS) Indy NVRAM, DS1386-8K-150. Have ordered a couple, hopefully they will be ok, not so sure about old stock though - if the battery is any good. After reading the semiconductor data sheet for the DS1386-8K-150, it seems that the battery is disconnected whilst in storage (bit 7):

TIME OF DAY REGISTERS
...
When set to logic 0, EOSC (Bit 7) enables the Real Time Clock oscillator. This bit is set to logic 1 as
shipped from Dallas Semiconductor to prevent lithium energy consumption during storage and shipment
(DIP Module only).

Battery may be disconnected which should increase the shelf life, but let's remember that batteries dry out just from being unused, so if it's a very old stock, don't expect miracles.
I've bought a couple of those from different source a two months ago, but didn't have the need to use them yet (my Indy still behaves).

cheers
