Preface  
Thank you for purchasing this user system interface cable (HS3937ECH61H) for the Renesas’s  
original microcomputer H8/3937R H8/3937 series.  
The HS3937ECH61H is a user system interface cable that connects an H8/300L series E6000  
emulator (HS388REPI60H; hereinafter referred to as the emulator) through the expansion board to  
the IC socket for a TFP-100B package for the H8/3937R H8/3937 series MCU on the user system.

Section 2 Connection Procedures  
2.1  
Connecting User System Interface Cable to Emulator Station  
WARNING  
Observe the precautions listed below. Failure to do so  
will result in a FIRE HAZARD and will damage the user  
system and the emulator product or will result in  
PERSONAL INJURY. The USER PROGRAM will be  
LOST.  
1. Always switch OFF the user system and the emulator  
product before the USER SYSTEM INTERFACE CABLE  
is connected to or removed from any part. Before  
connecting, make sure that pin 1 on both sides are  
correctly aligned.  
2. The user system interface cable dedicated to the  
emulator must be used.  
To connect the cable body to the emulator station, follow the instructions below.  
1. Make sure the user system and emulator station are turned off.  
CAUTION  
When connecting or removing the user system interface  
cable, apply force only in the direction suitable for  
connection or removal, while making sure not to bend or  
twist the cable or connectors. Otherwise, the connectors  
will be damaged. The user system interface cable must be  
connected to an H8/300L Series E6000 emulator through the  
H8/3937 Series expansion board. Do not connect the user  
system interface cable directly to the E6000 emulator.

2. [1] After making sure the direction of the expansion board connector labeled E6000  
EMULATOR is correct, firmly insert the expansion board connector into the emulator  
station connector ([1] in figure 2).  
[2] Connect the expansion board labeled USER INTERFACE CABLE and the user system  
interface cable body.

2.2  
Connecting User System Interface Cable to User System  
WARNING  
Always switch OFF the user system and the emulator  
product before the USER SYSTEM INTERFACE CABLE  
is connected to or removed from any part. Before  
connecting, make sure that pin 1 on both sides are correctly  
aligned. Failure to do so will result in a FIRE HAZARD and  
will damage the user system and the expansion board or  
will result in PERSONAL INJURY. The USER PROGRAM will  
be LOST.  
To connect the cable head to the user system, follow the instructions below.  
2.2.1 Installing IC Socket  
After checking the location of pin 1 on the IC socket, apply epoxy resin adhesive to the bottom of  
the IC socket for an TFP-100B package, and fasten it to the user system before soldering.  
2.2.2  
Soldering IC Socket  
After fastening, solder the IC socket for an TFP-100B package to the user system. Be sure to  
completely solder the leads so that the solder slops gently over the leads and forms solder fillets.  
(Use slightly more solder than the MCU.)  
5
 
 
2.2.3  
Inserting Cable Head  
CAUTION  
Check the location of pin 1 before inserting.  
Align pin 1 on the IC socket for an TFP-100B package on the user system with pin 1 on the user  
system interface cable head, and insert the user system interface cable head into the IC socket on the  
user system, as shown in figure 3.  
2.2.4  
Fastening Cable Head  
CAUTION  
1. Use a Philips-type screwdriver whose head matches the  
screw head.  
2. The tightening torque must be 0.054 N•m or less.  
If the applied torque cannot be accurately measured,  
stop tightening when the force required to turn the screw  
becomes significantly greater than that needed when first  
tightening. If a screw is tightened too much, the screw  
head may break or an IC socket contact error may be  
caused by a crack in the IC socket solder.  
3. If the emulator does not operate correctly, cracks might  
have occurred in the solder. Check conduction with  
a tester and re-solder the IC socket if necessary.  
6
 
 
Fasten the user system interface cable head to the IC socket for an TFP-100B package on the user  
system with the four screws (M2.6 x 12 mm; with flat washers) provided. Each screw should be  
tightened a little at a time, alternating between screws on opposing corners. Take special care, such  
as manually securing the IC socket soldered area, to prevent the soldered IC socket from being  
damaged by overtightening the screws or twisting the components.

Recommended Dimensions for User System Mount Pad  
Figure 5 shows the recommended dimensions for the mount pad (footprint) for the user system with  
an IC socket for an TFP-100B package (IC149-100-054-B51: manufactured by YAMAICHI  
ELECTRONICS Co., Ltd.). Note that the dimensions in figure 5 are somewhat different from those  
of the actual chip's mount pad.

Section 3 Installing the MCU to the User System  
CAUTION  
1. Check the location of pin 1 before inserting.  
2. Use a Philips-type screwdriver whose head matches the  
screw head.  
3. The tightening torque must be 0.054 N•m or less.  
If the applied torque cannot be accurately measured,  
stop tightening when the force required to turn the screw  
becomes significantly greater than that needed when first  
tightening. If a screw is tightened too much, the screw  
head may break or an IC socket contact error may be  
caused by a crack in the IC socket solder.  
4. If the MCU does not operate correctly, cracks might have  
occurred in the solder. Check conduction with a tester  
and re-solder the IC socket if necessary.  
Check the location of pin 1 before inserting the MCU into the IC socket on the user system, as  
shown in figure 8. After inserting the MCU, fasten the socket cover with the provided four screws  
(M2.6 x 6 mm; with flat washers). Take special care, such as manually securing the IC socket  
soldered area, to prevent the IC socket from being damaged by overtightening the screws or twisting  
the components.

Section 4 Verifying Operation  
1. When using the H8/300L series E6000 emulator (HS388REPI60H), turn on the emulator  
according to the procedures described in the H8/300L Series E6000 Emulator User's Manual  
(HS388REPI60HE).  
2. Verify the user system interface cable connections by accessing ports and checking the bus  
states of the pins. If an error is detected, recheck the soldered IC socket and the location of  
pin 1.  
3. System Clock (OSC2, 1)  
When the system clock is selected in the HDI Configuration Window and jumper P4 is set in the  
user system interface cable, the system clocks in table 2 can be selected (see figures 9  
and 10).

Section 5 Notice  
1. Make sure that pin 1 on the user system IC socket is correctly aligned with pin 1 on the cable  
head before inserting the cable head into the user system IC socket.  
2. The dimensions of the recommended mount pad for the user system IC socket are different from  
those of the MCU.  
3. To avoid breaking wires in the cable body, do not place heavy or sharp metal objects on the user  
system interface cable.  
4. While the emulator station is connected to the user system with the user system interface cable,  
force must not be applied to the cable head. Position the emulator station, user system interface  
cable, and user system as shown in figure 12.
