Points to consider when using the HT8051OCDS-ICE
●
Voltage and Current:
– The operating voltage of the HT8051OCDS-ICE can be within 2.0V~5.5V
– If the Power Out box is checked then the power supply to the Target Board will be provided
by the e-Link. If this item is not checked, an external power supply will be required
– In addition to the EV needing a VDD power supply, the other analog/digital circuit power
supplies may be connected with the OCDS operation. Refer to the datasheet to see if it is to
be provided by the user or to be connected with the VDD
– The maximum current for the power supply to the Target Board is 200mA. If the application
board current exceeds 200mA, an external power supply must be used
– When powered by the e-Link, if the load current becomes larger, the VDD output may not
be stable. It is recommended to take this into account during VDD setup
