1. GENERAL DESCRIPTION
The Winbond
'
s single chip ISDN S/T interface controller (W6690) 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 signalling and data
services. The PCM codec interface provides voice service or other services. For PC ISA bus add-on
card application, the built-in plug and play controller is used for automatic card identification and
resource assignment. The plug and play controller can be disabled for traditional ISA card
applications. Furthermore, an Intel or Motorola 8-bit micro-controller compatible interface is provided.
