Caution To Be Taken For This Product - Renesas Protection Board R0E330850ACBP0 User Manual

5. Precautions

Caution to Be Taken for This Product:

Be sure to connect this product to the user system, and supply power from the Vcc1 pin.
Use the power pin Vcc1 with 5.5 V or less. If the Vcc1 pin is set to 5.6 V or more accidentally, the LED1 and LED2
will light up to notify it. If the LEDs light up, turn the power off immediately.
If the pins protected against overvoltage are overvoltaged, the voltage of the Vcc1 pin may rise up to 5.6 V because
of reverse current. When you need to maintain the Vcc1 pin voltage of the user system, add dummy resistance and
voltage regulator diode to the power line of the Vcc1. (Figure 3 is a mounting example.)
Do NOT touch this product while powering on. Part of the circuit may be at a high temperature immediately after
turning off the emulator. Please take some time to let it cool down before touching this product.
Notes on This Product:
It does not provide any guarantees to protect the emulator from any possible improper connection with the user
system. For details, refer to the specifications.
When using this product, the electrical characteristics change slightly compared with when not using it. For final
evaluation or characteristics verification, use the evaluation MCU.
We cannot accept any request for repair. When requesting for repair of the emulator used with this product, refer to
"7. Troubleshooting" on page 6.
For inquiries about the product or the contents of this manual, contact your local distributor.
