4. Usage (See Figure 2) 
The R0E521258CFJ00 can be used for debugging and board 
mounted evaluation in common by mounting the 
NQPACK052SB on the user system. 
(1) For debugging 
Mount the NQPACK052SB and YQPACK052SB on the 
foot pattern of the user system in that order. And fix them 
with the YQ-GUIDE’s (do not use the screws included 
with the YQPACK052SB). 
After connecting the R0E521000EPB00 or 
R0E521000CPE00 and R0E521258CFJ00, connect the 
R0E521258CFJ00 to the YQPACK052SB. 
(2) For onboard evaluation 
Mount an R8C/24 and 25 Groups MCU and 
HQPACK052SB (separately available) in that order on the 
NQPACK052SB on the user system. And fix them using a 
screw included with the HQPACK052SB. 
Before using the R0E521258CFJ00, be sure to read "7. 
Precautions" on page 4 and the R0E521000EPB00 or 
R0E521000CPE00 User’s Manual.
