Hello, I am programming EPM3064ALC44-7 using JTAG-ByteBlaster. I will use the exact circuit shown in Figure 2 of application note AN-95 from Altera which describes connections to JTAG header and will also supply power to device through, VCCIO and VCCINT pins (3.3 Volts). However, I am trying to make a prototype board, which will only program devices using JTAG header (might seem crazy, but this is purely academic). Question: So, I need to know, how much current (Icc) is drawn by the device while only programming it (through pins VCCIO, VCCINT and JTAG pins on device), so that I can use a supply with minimum current requirement. Thanks, Drew
