2.6 Turning ON the Power
2.6.1 Checking the Connections of the Emulator System
Before turning the power ON, check the connection of the interface cable with host machine, PC7501, emulation probe, and
user system.
2.6.2 Power Supply to the User System
This emulator cannot supply the power to the user system. Therefore design your system so that the user system is powered
separately.
The voltage of the user system should be 2.7V
≤
VCC
≤
5.5V when the POWER selection jumper is set to the INT POWER side.
Do not change the voltage of the user system after turning on the power. To change the power supply voltage of the user
system, and the voltage of the user system is 2.2V to 2.7V, set the POWER selection jumper to the EXT POWER side. For
details about the POWER selection jumper, refer to “2.10.1 Setting the Jumper on the Emulation Probe R0E521000EPBM0”
(page 38).
When the POWER selection jumper is set to the EXT POWER side, this product consumes max. 500 mA of electrical current
from the user system. Please consider the capacity of the power supply of the user system.
2.6.3 Turning ON/OFF the Power
Turn ON the power of the emulator and user system as simultaneously as possible when the POWER selection jumper the INT
POWER side. Turn OFF the power of the emulator and user system as simultaneously as possible.
Do not leave either the emulator or user system powered on, because of leakage current the internal circuits may be damaged.
When the POWER selection jumper the EXT POWER side and the on-chip oscillator is operating, it is possible to turn
ON/OFF the power of the user system.
When turning ON the power again after shutting OFF the power, wait for about 10 seconds.
IMPORTANT
Note on the Emulator’s Pin VCC:
z
The emulator's pin VCC is connected to the user system in order to monitor user system voltage.
2.6.4 LED Display When the Emulator Starts Up Normally
Figure 2.4 shows upper panel LED lighting status when the emulator started up properly. Check it when starting up the
emulator system.
