Single-Chip Modem  
DATA SHEET  
K-Series devices are available with two control  
interface versions: one for a parallel multiplexed  
address/data interface, and one for a serial  
interface. The parallel version is intended for use  
with 8039/48 or 8031/51 microcontrollers from  
Intel or many other manufacturers. The serial  
interface can be used with other microcontrollers  
or in applications where only a limited number of  
port lines are available or the application does not  
lend itself to a multiplexed address/data interface.  
The parallel versions may also be used in the  
serial mode, as explained in the data sheet pin  
description.  
APPLICATIONS INFORMATION  
GENERAL CONSIDERATIONS  
Figures 1 and 2 show basic circuit diagrams for  
K-Series modem integrated circuits. K-Series products  
are designed to be used in conjunction with a control  
processor, a UART or RS-232 serial data interface,  
and a DAA phone line interface to function as a typical  
intelligent modem. The K-Series ICs interface directly  
with Intel 8048 and 80C51 microprocessors for control  
and status monitoring purposes. Two typical DAA  
arrangements are shown: one for a split ±5 or  
±12V design and one for a single 5V design. These  
diagrams are for reference only and do not represent  
production-ready modem designs.  
In most applications the controller will monitor the  
serial data for commands from the DTE and the  
received data for break signals from the far end  
modem. In this way, commands to the modem are  
sent over the same line as the transmitted data. In  
other applications the RS-232 interface handshake  
lines are used for modem control.
