Manufacture and supply of the SPM ASIC will be discontinued as              

per the end of December 1996.                                               


The PROFIBUS SPM ASIC is designed for simple field devices, such            

as I/O stations. It was one of the first field bus ASICs for                

PROFIBUS and does not meet the subsequently introduced PROFIBUS-            

DP Standard. The new SPM2 ASIC that conforms to the standard has            

been available for the past year and has the same number of I/O             



In view of the fact that the ET 200 distributed I/O system has              

been converted to the Standard and SIMATIC S7 supports only stan-           

dard PROFIBUS DP devices, sales of the SPM ASIC will be discon-             

tinued as per the end of Dec. '96.                                          


Last orders can be placed until that date.
