4.4.3 Analyzer input connector
An analyzer input connector is located on the EMU3 probe as shown in Figure 21 . The
analyzer input connector allows you to use 8 external input signals (TTL level). The
connector has nine pins—one ground pin (the right-most pin) and eight input signal pins (1-
8), as shown in
Figure 22 .
Figure 22. Analyzer probe input connections
A specially-adapted 9-wire cable is included to connect your application or an external
device (such as an oscilloscope or multi-meter) to these inlets. Each wire is color-coded as
summarized in
Table 2 :
4.4.4 Application power supply follower
Your emulator is equipped with an automatic power supply follower, which converts your
application power to the range supported by the emulator. The emulator’s internal power
supply regulator supports a V
DD
voltage up to 5.5 V. The lower limit of the range depends on
the ST7 you are emulating. For more information, refer to your ST7xxxx Datasheet.
If your application’s voltage lies outside of the range supported by your emulator or your
ST7, the emulator’s power supply follower will convert the voltage to within the appropriate
range – for example, even if the application voltage is 6 V, it will be limited by the emulator to
5.5 V.
