Functions

The HFC-S mini is a single-chip ISDN S/T HDLC basic rate controller for embedded applications.
The S/T interface, HDLC-controllers, FIFOs and a microprocessor interface are integrated in the HFC-S mini.
A PCM128 / PCM64 / PCM30 interface is also implemented which is able to connect to many telecom serial busses. CODECs are usually connected to this interface. All ISDN channels (2B+1D) and the PCM interface are served fully duplex by the 8 integrated FIFOs.
