The R0E436640CFK20 can be used for debugging and board 
mounted evaluation in common by mounting an IC socket on 
the user system. 
(1) For debugging 
Mount the IC socket on the foot pattern of the user system 
in that order. 
After connecting the R0E436640CPE00 and 
R0E436640CIF00, connect the R0E436640CFK20 to the 
IC socket. And fix them with the screws (M2 x 12mm) 
included with the R0E436640CFK20. 
(2) For onboard evaluation 
Mount an H8/300H Tiny Series MCU in that order on the 
IC socket on the user system. And fix them with the 
screws (M2 x 6mm) included with the R0E436640CFK20. 
Before using the R0E436640CFK20, be sure to read "7. 
Precautions" on page 4 and the R0E436640CPE00 User’s 
Manual.
