Pablop Posted March 5, 2008 Report Share Posted March 5, 2008 I´ve designed this little PCB for a Bankstick of four Atmel EEPROMs "24C256".I´d like to check this with the people in the forum before I continue. And, if it´s correct, I hope someone finds it useful.Thanx,Pablo PUpdate: I removed this version because it had some little bugs. See below.

julienvoirin Posted March 7, 2008 Report Share Posted March 7, 2008 i can send you the design for 8 bankstick if you like. it fits on a very small board and works (i use it in the seq) and can be opened with the free eagle soft. Quote Link to comment Share on other sites More sharing options...
Pablop Posted March 8, 2008 Author Report Share Posted March 8, 2008 I thank you, that'd be nice.Thing is what I found are 24C256 from atmel, which have only two pins for chip select, thus giving a max of 4.I checked and double-checked the board, and seems to be fine. But since it's the first one I design I wanted to check it out. Quote Link to comment Share on other sites More sharing options...
Pablop Posted March 20, 2008 Author Report Share Posted March 20, 2008 The PCB is OK and working. It's useful if you have Atmel's eeproms. They will allow just 4 ICs to be used together. So this PCB is for a bankstick made of four chips. I'm adding a slightly updated design for those who could find it handy. There are two differences: First one is that it makes clear where the two bridges should be placed. Second, and maybe more important, there was a confusion regarding the labels of the pins in J1. sc should have been sd and viceversa.Cyabankstick4p.rarbankstick4p.rar Quote Link to comment Share on other sites More sharing options...
