NEC uPD7201C Datasheet, Pinout?

Hi guys, I've looked trough my Z80 Stuff some minutes before b'cause a friend wanted an Z80A CPU, ok found it. In a Bag 6 uPD780-1 which are also Z80A's, I found two uPD7201C. I've googeled some time before that the uPD7201A is some Z80-SIO - alike, has an other Pinout for example and should be compatible to some Intel chip which is mostly a clone of the Z80-SIO also. (maybe to give the Intel world acess to a usable USART to this time) But: I can't find a datashet for the uPD7201C using google or the usual suspects, can someone help out here? I think possibly this isn't just a different letter, maybe it means that this is the Zilog compatible Version with the Zilog Pinout? Does anyone know something about it or has a datasheet? Next interesting thing are 10 pcs. of NS405-B18N, a sticker says that that are display processors, someone knows where tehy where used in? Kind Regards, Holm -- Technik Service u.
