4.0 Powering the Target System 

4.1 Overview 

This section explains the different options available for powering the 

‘Target System’

 

It is possible to power the 

‘Target System’

. either from an 

‘external power supply’

 or by utilising the 

‘Programmer Controlled Target Power Supply’

 

Target System 
powering method 

Voltage range 
(V) 

Power supply used to power the Target 
System 

Independently powered  3.0 – 5.0 

External Power Supply 
e.g. bench supply 

Powered from the 
programmer 

Pre-set 
voltages: 
3.0V, 3.3V, 
4.7V or 5.0V 

Programmer Controlled Target Power Supply 

 
The programmer is only capable of generating 4 different pre-set target voltages: 3.0V, 3.3V, 4.7V or 
5.0V.
