IA80C152  
Preliminary Data Sheet  
UNIVERSAL COMMUNICATIONS CONTROLLER  
The GSC is a serial interface that can be programmed to support CSMA/CD, SDLC, user definable  
protocols, and limited HDLC. Protocol specific features are supported in hardware such as address  
recognition, collision resolution, CRC generation and errors, automatic re-transmission, and  
hardware acknowledge. The CSMA/CD protocol meets the requirements of ISO/IEC 8802-3 and  
ANSI/IEEE Std 802.3 to the extent implemented in the original IC. The SDLC protocol meets  
the requirements of IBM GA27-3093-04 to the extent implemented in the original IC.  
Functional Block Diagram  
Figure 4 shows the major functional blocks of the IA80C152. Each version of the IA80C152  
function identically to each other with the exception of the 2 additional I/O ports (Port 5 and  
Port 6) in the JB and JD versions.
