3.0 Programmer / Target System Power
Supply Scenarios + Standalone Mode
Programming Instructions
3.1 Overview
The EPSILON5 programmer has been designed so that it can be powered both directly from a Target
System (3.1 – 5.0V) and also from an external power supply (3.1 – 5.0V). This makes the
programmer ideal for both standalone use (not connected to a PC) and development use (connected
to a PC). The programmer can be powered from Target System voltages as low as 3.1V allowing it to
be used to program 3.3V Target Systems in the field (eg. on vehicles) without requiring the use of an
external power supply.
Please refer to the table below to choose the required 'Power Supply Scenario'. The relevant section
also gives detailed instructions on how to operate the programmer in 'Standalone' mode for the
chosen 'Power Supply Scenario'.
