2. Cautions
1. Do not look into the LED beam!
Special care must be taken with the high power LEDs
2. When power supply of E1 On-Chip debugger is used please note that the maximum
current provided by the debugger is limited to 200mA. Thus an external power
supply is required in case all functions on the StarterKit are used to full extend.

4.2.1 Power Supply
4.2.1.1 Power supply configuration
The StarterKit provides two options for powering the board’s integrated circuits. It is possible to
supply the StarterKit by using the E1 Debugger or it is possible to supply the StarterKit by using
an external 12 Volt power supply.
With the default jumper setting (see 0) the StarterKit is configured to be power supplied by the E1
Debugger.
The operation of the LIN and the FlexRay interface is only possible by using an external 12 Volt
power supply.
When the board is supplied externally by 12 Volt, please choose the following jumper settings:

4.2.2 Microcontroller Area and Port Pin Interfaces
On the different versions of the RH850/F1x StarterKit the following device are assembled:
Y-ASK-RH850F1L-V3: R7F701057
Y-ASK-RH850F1K-V3: R7F701587
Y-ASK-RH850F1H-V3: R7F701527
Y-ASK-RH850F1KM-S4-V3: R7F701649
Y-ASK-RH850F1KH-D8-V3: R7F701709
As external clock supply of the microcontroller, a 16MHz crystal oscillator and a 32.768kHz sub-
oscillator is mounted.
Each microcontroller I/O pin is connected to a pin header interface. The pin header interfaces
allow easy probing of I/O pins and provide the ability to selectively connect the I/O pins to power,
ground or other signals. Table 1 and Table 2 are showing the assignment of the pin header
interface.
Certain GPIO pins of the device might not be available on all StarterKit versions. An overview of
these pins can be found in Table 10.

Table 11. Port power supply groups
In the RH850/F1H, F1KM-S4 and F1KH-D8 versions of the board a 3.3V regulator is supplied to
provide the required voltage for the Ethernet transceiver. This voltage is supplied to the BVCC
Pin Group Power Supply and will affect the ports P10, P11, P12 and P18 (blue area in Figure 8).
All other port pins operate at 5 V (red area in Figure 8). For RH850/F1L and RH850/F1K all port
pins operate at 5 V.
4.2.3 LEDs
4.2.3.1 RGB LED
A RGB LED is provided to allow visual observation of microcontroller output port state and to
show the functionality of the PWM Diagnostic Macro. The RGB LED, which is part of the Rotary
Encoder, is driven by three N-channel transistor. A feedback for each RGB LED channel is
