RL78/G1P Fast Prototyping Board

6. Handling Precautions

6.1

Power to be Supplied

The maximum current that the power-supply IC (ISL9005AIRNZ-T from Renesas) can supply is 300 mA
during operation at 3.3 V.
If power is to be supplied to this product via the USB, take care with the regard to the load that the USB-power
source is capable of driving.
6.2

Remodeling the Board

Any modification of the board (including removing the patterns for cutting) shall be conducted at the user's
own responsibility.
6.3

Limitation on the Number of Connected RL78/G1P Fast Prototyping Boards

Connecting the same host PC to multiple RL78/G1P Fast Prototyping Boards is not possible.
6.4

Power-Supply Circuits and Usage Conditions

Different power supplies can be selected by remodeling the board. Table 6-1 shows the relationship between
power-supply circuits and usage conditions.
