Hi all.
Im tearing down an old Cisco IP phone that Ive had forever but which I no longer use (7940G). I thought I'd see if there was anything interesting/useful inside it that might make for a rainy day project some time.
Maybe about the only interesting thing so far (its full of ASICs, of course) is the LCD, but it has an interface that Ive not come across before.
Im wondering if anyone might happen to know if this fits some kind of standard or common interface, and/or whether there is a datasheet floating around somewhere that would detail how to drive the LCD itself?
I figure I might try to build a breakout board for it so that I could potentially use it in a project, or just muck about with it.
It appears to have an 8 bit interface that I traced to the 74FCT3573 which is right at the bottom of the photo. From there it then disappears into a Cisco branded ASIC of some kind (possibly just a branded FPGA, Ive seen them do this in other products).
Thanks!
