Power Supply Package - TASKING ST SPC58 2B LINE Hardware User Manual

Power supply package

Use the enclosed IEA-PS Emulation Adapter Power converter and adapter. A Power supply
package, which is delivered with the Emulation Adapter, is required when:
·
The Emulation Adapter is used as a standalone device.
·
The target board doesn't provide an accurate supply voltage.
·
The target board doesn't provide sufficient current for the Emulation Adapter operation.
The Power converter can supply either 3.3 V or 5 V. The array of jumpers J0–J9 selects 3.3 V or 5
V voltage on the P3 connector, which connects to the Emulation Adapter.

For example, when J2 is in the 3V3 position, it supplies 3.3 V to pin 6 of the P3 connector. When
J2 is in the 5V position, it supplies 5 V to pin 6 of the P3 connector pin.
Be careful not to supply 5 V to the microcontroller power supply pin, which has declared
a maximum voltage 3.3 V! Refer to the microcontroller documentation for detailed
information on power supply.
