24C02W6 Datasheet, PDF – Alldatasheet

What kind of laptop are we talking? Thank you in advanced, Peter Attached is an image of the chip and a data sheet for 24cx. Nuneaton Warwickshire My Country: I posted this on a older thread I have and just wanted to make a new thread in the event that someone has some questions later in life this might be easier to come across.

Last edited by Peter9DO; at I’m running out options to try with no luck thus far I’m debating swaping out the chip itself, but I’m not sure if the 24c0w6 IC has built in memory or is it linked to a memory modual.

Just to let you know the way I’m doing it, I’m attaching a wire to whatever pin combo and then turning the computer on. So, does that mean every time you shut the computer down you’re resetting the BIOS chip? I have done all 3 of these combinations with no results! I believe I have found the schematics for this chip, but seeing the actual chip is obsolete I’m going off of an ROHS version that I think is the same.

Not sure if it is case sensitive? Okay, so after reviewing the datasheet which is the correct one may I add and taking some readings. Vel mihi ede potum vel mihi redde nummos meos!

If someone could please help me and just run through the process of shorting the chip to verify that I’m doing this all properly and to make sure I have done the right pin combination, I would be in debt to you!

Last edited by trebo; at First S and Datasbeet Did the thread i linked have more detailed info on pin shorting? Thank you for all the help that everyone has provided thus far!


Find More Posts by gilly The time now is In a similar way, during power-down continuous decrease in VCCas soon as VCC drops below the power-on-reset threshold voltage, the device stops responding to any instruction sent to it. The 24C02W6 IC has a device reset within it. I only glanced at that thread but it was though folks would pass over their info and have a mpw given in response Originally Posted by Peter9DO.

Originally Posted by 2andrewd. Okay, so now I’m going to 24c022w6 read through the data sheet and I will be back later! Because I think it would be pointless if there is a diffent chip datasbeet the memory, because the settings are stored elsewhere. Min Vcc for this IC is 2.

Well, I was working on the laptop and retracing my steps, make sure I was doing things right seeing that I have worked on this so long ago I don’t remember what I had completed seeing my notes on this one were not very complete, I’m sure out of pure frustration. Let me ask what i should have asked to begin with
