Data Sheet
1. GENERAL DESCRIPTION
W66910 PCI ISDN S/T-Controller
The Winbond's single chip TE mode ISDN S/T interface controller (W66910) is an all-in-one device suitable for ISDN Internet
access. Three HDLC controllers are incorporated in the chip, one for D channel and the other two for B channels. These HDLC
controllers facilitate efficient access to signaling and data services. It also provides 8-bit microprocessor interface to serve as
general purposed controller for embedded applications.
