3.0 BLUEBOARD-RL78/G12/G13/G14_30pin Hardware Description
3.1 Introduction
The NGX BLUEBOARD-RL78/G12/G13/G14_30pin is based on RL78/G12/G13/G14_30pin
microcontroller from RENESAS. RL78/G12 offers 16 KB, RL78/G13 offers 48KB, RL78/G14 offers
64KB Flash memory, 32-MHz operation, ADC: Up to 8 channels, 10-bit resolution, 2.1µs conversion
time, D/A converter: 2 channels, 8-bit resolution, On-chip temperature sensor and wide range of
peripherals. Refer to the RL78/G12/G13/G14 data sheet for complete device details.
BLUEBOARD-RL78/G12/G13/G14_30pin microcontroller is factory-programmed with a quick start
demo program. The quick start program resides in RL78/G12/G13/G14_30pin on-chip Flash memory and
runs each time power is applied, unless the quick start has been replaced with a user program.

4.0 BLUEBOARD-RL78/G12/G13/G14_30pin hardware verification
NGX's BLUEBOARD-RL78/G12/G13/G14_30pin board evaluation platforms ship with a
factoryprogrammed test firmware that verifies the BLUEBOARD-RL78/G12/G13/G14_30pin board
peripherals. It is highly recommended that you verify the board, before you start programming. Also this
exercise helps you get acclimatized with the board quickly.
To run the tests you will need the following:
BLUEBOARD-RL78/G12/G13/G14_30pin

4.2 Powering the Board
The BLUEBOARD-RL78/G12/G13/G14_30pin requires DC supply of 6.5V.1A rating to power it up,
alternatively the board could be powered through Emulator.
4.3 Verifying all the peripherals BLUEBOARD-RL78/G12/G13/G14_30pin board
The following section focusses on the verification of all the peripherals supported on the BLUEBOARD-
RL78/G12/G13/G14_30pin board. The order of the tests is mentioned in the same manners as the flow of
the test firmware. We highlyrecommend that you follow the order of the test. The testfirmware is designed
in a manner that the user needs to spend as minimum time as possible to verify all the peripherals.
Note: It is highly recommended that the user tests all the peripherals as soon as the board is received.
Power up the board and we are all set to verify the BLUEBOARD-RL78/G12/G13/G14_30pin board
peripherals. The order of the peripherals that are verified by the firmware are as follows:
4.3.1 LED
Test setup and verification:
As soon as the board is turned ON or reset; the test LED (D1) go ON & OFF for a couple of times, this
simple test validates the LED.
4.3.2 BUZZER
Test setup and verification:
When the board is turned ON or reset you will hear a beep after few seconds. This confirms the status of
the Buzzer.
4.3.3 USER SWITCH
Test setup and verification:
When you press the User Switch, LED (D1) toggles.

4.3.4 ADC
Test setup and verification:
The ADC pin is connected to a potentiometer. To test the ADC rotate the wheel of the potentiometer, as
the position varies the ADC value sensed is displayed on the UART1 port. Open the hyper terminal as
shown in the Fig 6, 7 and 8.
Note: Since the RL78/G12/G13/G14 has a 10-bit ADC, the values of the ADC reading will range from
0x0000 to 0x1023.
Fig 5
4.3.5 UART0 and UART1
Note: The UART0 and UART1 test is not there in the factory-programmed test firmware , user need to
load the UART0 and UART1 sample firmware separately then follow the below steps. To load the
firmware follows the steps in section 3.2 in the user manual.
Test setup and verification:
Open the hyper terminal as shown in the below image. To test the UART0 and UART1 open the hyper
terminal with settings 9600bps 8N1, i.e.
Baud Rate: 9600 bps
Bits: 8
Parity: None
Stop bits: 1
Flow Control: None
Note: On RL78/G14 board UART0 lines are not available; UART0 pins of RL78/G14 are not pin
compatible with UART0 pins of RL78/G12/G13.

A ‘Connect To’ window opens where you have to select the COM port. In this example it is COM26.Click
OK. A ‘COM26 Properties’ window appears. Set the values as shown below. Click OK.
Note: Please check for your machines COM port number. The COM port number can be different.

Next a ‘Hyper Terminal’ window opens as shown.
Fig 9
4.3.6 Supply Voltage Adjustment Pot
Test setup and verification: This pot demonstrates the MCU can work for variable voltages i.e 1.6 V to
5.5 V. We have verified user LED (D1) blinky at voltage 1.8V.
Adjust the pot to set the voltage between the specified ranges and test the user LED (D1) blinky, LED
(D1) should toggle.
