1.5.3 Current Consumption / Parameters
1.5.3.1 Current Consumption
The programmer can either be powered from the Target System via one of the ISP Headers or from
an independent power supply via CON1. The table below details the programmer current
consumption with a supply voltage of 5.0V and 3.3V for both ‘Standby’ mode and during a typical
programming operation when the programmer is independently powered. If the programmer is to be
powered from the Target System (typical of field use), then the Target System power supply must be
capable of supplying the maximum current that can be drawn by the programmer during a
programming operation.

Notes:
The above measurements were taken with the programmer and Target System independently
powered (i.e. J9 removed). EPSILON BOM – 1.20/1.21. Target device – AT90S8515.
These measurements refer to the current taken by the programmer’s internal circuitry.
Standby Mode – All LED’s OFF (Target Vcc is OFF so the Target Vcc LED is also OFF)
1.5.3.2 Maximum Current handling of programmer
If the programmer is supplying power to the Target System, then the current drawn by the Target
System must be below the maximum value stated in the table below.
