Notes:
The specification of the grove connector is on the assumption that Grove modules are to be connectable through I2C. If a connector is mounted, however, connection to all Grove modules (through I2C) is not guaranteed. Use this connector after having confirmed the specifications of this product and Grove modules (through I2C) you intend to use.
Figure 5-3 and Table 5-7 show the pin assignments of the Grove connector.

Clock circuits are provided to handle the clock sources for the evaluation MCU. For details on the specifications of the evaluation MCU clocks, refer to the RL78/G16 User's Manual: Hardware. For details on the clock circuit of this product, refer to the circuit schematics of the RL78/G16 Fast Prototyping Board. Table 5-8 shows the details of the clocks on the RL78/G16 Fast Prototyping Board.
Table 5-8 Details of Clocks
Clock | Function and Usage | State as Shipped | Frequency | Package for the Oscillator |
OSC1* | Crystal oscillator for the main system clock (e.g. CSTNE12M0G52x from Murata Manufacturing Co., Ltd.) | Not mounted | n/a | SMT |
OSC2* | Crystal oscillator or ceramic resonator for the main system clock (e.g. CSTLS10M0G53x from Murata Manufacturing Co., Ltd.) | Not mounted | n/a | Lead type |
OSC3 | Crystal oscillator for the sub clock | Mounted | 32.768 kHz | SMT |
Note: Use the main system clock by cutting the patterns for cutting [SS01] and [SS02] and short-circuiting the shortcircuit pads [SC01] and [SC02]. Note that the main system clock cannot be used at the same time as the subclock.
Pressing the reset switch (RST) applies a hardware reset to the evaluation MCU.
An optional user switch (SW) is mounted. It is connected to pin 4 of the evaluation MCU, which operates as pin function P137. The INTP0 interrupt is multiplexed on the same pin.
A USB-to-serial converter (FT232RQ) from FTDI is mounted on the board and is usable with the standard driver of Windows 10. For other operating systems, install the driver by downloading from the following Web site of FTDI.
https://www.ftdichip.com/
DRIVERS > VCP Drivers
The USB-to-serial converter reset header (J13) is open-circuit; it is recognized as a COM port when the host PC is connected to this board via a USB cable.
As the interface with the RL78 COM port debug tool, the USB-to-serial converter enables debugging and programming of the evaluation MCU. Refer to Chapter "Developing Code". Note that the P40, P01, and P00 pins of the evaluation MCU are respectively occupied as the TOOL0, TOOLRxD, and TOOLTxD functions.
When the RL78 COM port debug tool is in use, use of the P125/RESET pin as the P125 port pin is prohibited. Do not make the option byte setting for using P125.
If P125 is mistakenly set, COM port debugging and writing will become unavailable. If you are unable to use COM port debugging or writing, please recover by erasing the program using an E2 emulator or E2 emulator Lite connection, or by using the 'COM Port Connection Recovery Application for Fast Prototyping Board' (R01AN7363).
For the method of COM port debugging, refer to the application note, RL78 Debugging Functions Using the Serial Port (R20AN0632).
When the USB-to-serial converter is not used as the interface with the RL78 COM port debug tool, using the RxD0 and TxD0 functions of the P01 and P00 pins enables UART communications between the host PC and the evaluation MCU. The user needs to prepare the terminal software, such as TeraTerm.
The USB-to-serial converter is placed in the forced reset state by short-circuiting its reset header (J13). If the evaluation MCU alone is to operate without the use of the RL78 COM port debug tool, place the USB-to-serial converter in the reset state. This allows the use of P01 (RxD0) and P00 (TxD0) as facilities other than for a UART, such as port pins, while a reset is being applied to the USB-to-serial converter. Even if P11 and P12 are used as facilities other than for a UART, such as port pins, the board must be connected to the host PC by using the USB cable. Figure 5-4 shows the position of the USB-to-serial converter reset header.
The operating power (VDD) of the evaluation MCU can be changed to supply from the emulator or external power, and to 5 V or 3.3 V with the use of a header (J15). Only change the jumper setting of J15 while power is not being supplied.
When the evaluation MCU is to have a desired power-supply voltage, or when more current is required, use an external power supply. The usable voltages depend on the evaluation MCU.
Destinations for the connection of an external power supply:
Figure 5-8 shows the positions of the external power supply.
When an external power supply is used, confirm that the I/O voltages for Arduino® shields, Pmod™ modules, or Grove modules are correct.
This header (J9) is used to measure the current drawn by the evaluation MCU (J9 header components are not mounted). Connecting an ammeter to this product enables measurement of the current being drawn by the evaluation MCU. Take care to cut the given pattern for cutting (SS18) if this header is to be used. Figure 5-9 shows the positions of the current measurement header and pattern for cutting.
Insert an ammeter between the sockets of the current measurement header (J9) to measure the current. Cut the pattern for cutting (SS18) (Figure 5-11) and turn down the LED to reduce the current drawn with an MCU other than the evaluation MCU.
Figure 5-10 is a block diagram of the power-supply lines related to the measurement of current drawn. For a block diagram of the power-supply circuit as a whole, refer to Figure 6-2.
If you intend to use this board without connecting a USB connector, cut the given pattern for cutting (SS14). Figure 5-11 shows the position of the pattern for cutting.
This 14-pin connector (J8) is used to connect this product to an on-chip debugging E2 emulator or E2 emulator Lite, from Renesas Electronics, incorporating programming facilities. The emulator is used for programming or debugging the evaluation MCU.
To connect the emulator, change the circuit as follows.
For the usage of the emulator, refer to the E1/E20/E2 Emulator, E2 emulator Lite Additional Document for User's Manual (Notes on Connection of RL78) (R20UT1994).
If you use COM port debugging with the use of the USB-to-serial converter, make the following change to settings as follows.
When power is supplied to this product from an emulator or through the USB, note that the total current of VDD, 5 V, and 3.3 V should not exceed the maximum current of 200 mA.
Any modification of the board (including cutting the patterns for cutting) shall be conducted at the user's own responsibility.
The following shows the settings of jumpers as shipped.
In this document, "short-circuit pads" refers to pairs of pads for short-circuiting by solder.
"Pattern for cutting" refers to a narrow signal pattern in the middle part between two short-circuit pads. When you cut the pattern for cutting, do not cut over the silkscreened frame of a white ellipse.
In some cases, a pattern for cutting may not be visible because it has been covered with coating of a resist. Also refer to the circuit schematics.
In the circuit schematics, the symbol below indicates that there is a pattern for cutting between short-circuit pads.
In the circuit schematics, the symbol below indicates that there are only short-circuit pads without any pattern for cutting.
Different power supplies can be selected. Table 6-1 shows the relationship between power-supply sources and usage conditions.
Figure 6-2 shows the block diagram of the power-supply circuit.

Notes:
When you are using QE for Capacitive Touch (QE) with this product, change the circuits in the following cases (1) and (2).
For the methods for developing touch applications with the use of QE in the RL78/G16 MCU, refer to the application note "RL78 Family Using the standalone version of QE to Develop Capacitive Touch Applications" (R01AN6574).
When the power is turned on or immediately after release from resetting of the USB-to-serial converter of this product, if a user program which starts the output of the UART transmission to the P00/TxD0 line is written to the target MCU before the host PC recognizes the USB-to-serial converter as the COM port, the operation of the USB-to-serial converter may be unstable and prevent connection to the Renesas Flash Programmer or terminal software.
In such cases, turn on the power (connect the USB cable) while pressing the reset switch, wait about 3 seconds until the host PC recognizes the USB-to-serial converter as the COM port, and release the reset switch. Otherwise, reset the USB-to-serial converter (by briefly short-circuiting J13 and then restored it to open-circuit) while pressing the reset switch, wait about 3 seconds until the host PC recognizes the USB-toserial converter as the COM port, and release the reset switch.
