Re: [ukvac] [Tech] What is timekeeping ram?
These are Non-Volitile RAMs with a clock module.
They are used in systems that require a real-time clock that functions when
power is turned off.
DS1643 are normally found in old IBM PC.
Problem is they have a Lithium battery built in - sealed in the epoxy
package - and this normally lasts for about two years when left on the shelf
and for 6 years when actually in somthing and used regularly
They are still a current Dallas part so unless they are newish, best place
for them is the odds-sods department
