1. GENERAL DESCRIPTION
The Winbond's single chip PCI bus ISDN S/T interface controller (W6692A) 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. The built in PCI 2.2 interface circuit makes glueless
design for PCI bus add-on card application. It also provides 8-bit uC interface to serve as general purposed controller for
embedded applications.
