RAJ306010 RSSK(RTK0EML2C0S01020BJ)
4. Function
4.1
Power supply
The board operates by supplying a single power supply of 6V to 42V to the J4 (VM input pin) and J6 (GND input
pin) pins. And, the 5V built-in regulator of RAJ306010 operates to supply 5V to the peripheral circuits and
VDD.
Note.1
When using any motor, refer to "4.3.4" and supply the voltage according to the motor within the operating range
of RAJ306010. (When using the motor included in this kit, supply 24V.) In addition, fuses are mounted on TB100
and TB101 of this board. Replace the fuse capacity according to the motor current to be controlled.
When using external MOSFET and shunt resistor mounted on this board, refer to "4.3.5 When using an external
MOSFET board" and connect the external MOSFET board power and GND to J3 and J5.
This board is equipped with J1/J2 to supply external 5V power without using RAJ306010's built-in regulator. For
details, refer to "4.16 5V Power Supply Selection Function".
Note.1 When using the attached motor, apply 24V ± 10% to J3 (VM connection terminal) and J6 (GND connection terminal).
4.2
Emulator connection
To rewrite or debug the firmware of RAJ306010, use an emulator compatible with RL78 manufactured by
Renesas Electronics. Connect the emulator to the emulator connector (CN_E1).The pin assignment of the
Emulator connector is shown below. This pin assignment is compatible with the cable that comes with the
Renesas emulator.
