Re: RICOH Chipset RL5E823 & RL3E851 give more details

As I want to help you in sourcing this part & get the Datasheet,
Please could you give us the pkg and pins of those two chips.
also , please give us the name of the equipment on which they are.
because perhaps I could find you a diagram on which they are.
are they parts of printers, copiers, gsms??
do you have a picture or photo of those chips you could upload?
Are you Sure that they are manufactured by Ricoh : what is the logo
& other markings,

Yes, it's from Ricoh

There's that big RICOH sign on the chip, both of them are from the DVD /CD writer, I suspect they might custom ASICS. Both of them are in TQFPs.

Re: Yes, it's from Ricoh

OK. Sir,
But give me the exact reference from this CD/Writer :
what is the part Number?
Yes because in fact it is possible to get the full diagram of it
but w/o any reference I cannot do it a search for you.
