ID chip content
The ATBTLC1000ZR Xplained Pro can be connected to several Xplained Pro MCU boards and manually
connected to other hardware. Xplained Pro MCU board(s) that does not have 3.3V as its primary target
voltage reads all ID devices on connected extensions to check if they support the target voltage before
enabling it to the extension headers. The table provides the static content written in the ID chip.
