Brief Description 

The PE0403 Platform Evaluation Kit is designed to assist in the evaluation and application development of 
the  CMX724x  and  CMX734x  ranges  of 

FirmASIC

®

  products.  The  kit  is  in  the  form  of  a  populated  PCB 

comprising a generic CMX7240 or CMX7340 IC and the appropriate supporting components and circuitry.

 

The

 

PE0403 - 724x is fitted with a CMX7240 and the PE0403 - 734x is fitted with a CMX7340. 

The  board  also  incorporates  all  of  the  necessary  power-supply  regulation  facilities  for  operation  from  a 
single 5 volt supply, or a dual +/-5 volt supply if the instrumentation interface is required. 

The board is fitted with a C-BUS connector allowing the PE0403 to be operated by connection to either of 
the two C-BUS ports on a CML PE0002 Interface Card, and used with the associated PC GUI software, or 
by direct connection between the CMX7240/CMX7340 C-BUS and the user's µC development application 
or emulation system. 

The common CMX724x/CMX734x Function Image

TM

 (FI) can be loaded, on power-up, directly into the on-

board target IC (CMX7240/CMX7340) using the PE0002 interface or the user's system. 

Function images suitable for the CMX724x/CMX734x range of products can be downloaded from the CML 
Technical Portal.
