Hi everybody!
In EEPROM we usually use a charge pump circuit,and in charge pump circuit we have a pumping clock to control! But, i don't know what pin of EEPROM connect to this clock!!! Can anyone explain to me! thanks alot!

Re: charge pump

What is the specification of the EEprom?
Do you have a Datasheet?

Re: charge pump

In EEPROM people use charge pump to provide voltage larger than voltage supply! so i think almost EPROM, EEPROM use charge pump! but in datasheet i can't find the pin for pump clock!!

charge pump

Very simple explanaition. Internal chargepump is usually supplied by own oscillator. That is why u don't able to find pin for clock.

Re: charge pump

So, the charge pump circuit must have self-osillator circuit??

yes, because we need not accurate clock, so we use intarnal osillator circuit.

charge pump

yes, the ring oscillator is used for charge pump clock.
