2.2.2 Power Supply from Target System
The BDI1000 needs to be supplied between 2.5V and 5V via TARGET A connector. This mode can
only be used when the target system runs between 2.5V and 5V and the pin «Vcc Target» is able to
deliver a current up to:
• 900mA@2.5Vcc Target
• 700mA@3.3Vcc Target
• 450mA@5.0Vcc Target
For pin description and layout see chapter 2.1 «Connecting the BDI1000 to Target». Insert the en-
closed Jumper as shown in figure below. Please ensure that the jumper is inserted correctly.
For error-free operation, the power supply to the BDI1000 must be between 2.5V and 5V DC. The
maximal tolerable supply voltage is 5.25 VDC. Any higher voltage or a wrong polarity might
destroy the electronics.
