Hardware Revision History and Known Issues

6.1.

Identifying Product ID and Revision

The revision and product identifier of Xplained Pro boards can be found in two ways; either through Atmel

Studio or by looking at the sticker on the bottom side of the PCB.

By connecting an Xplained Pro MCU board to a computer with Atmel Studio running, an information

window will pop up. The first six digits of the serial number, which is listed under kit details, contain the

product identifier and revision. Information about connected Xplained Pro extension boards will also

appear in the Atmel Kit's window.

The same information can be found on the sticker on the bottom side of the PCB. Most kits will print the

identifier and revision in plain text as A09-nnnn\rr, where nnnn is the identifier and rr is the revision.

Boards with limited space have a sticker with only a QR-code, which contains a serial number string.

The serial number string has the following format:

"nnnnrrssssssssss"

n = product identifier

r = revision

s = serial number

The product identifier for SAM C21 Xplained Pro is A09-2419.

6.2.

Revision 6

Revision 6 has silicon revision D or newer of the ATSAMC21J18A-AUTES (U300) device mounted, it is

otherwise identical to revision 5.

6.3.

Revision 5

Revision 5 fixes all known issues outlined on rev. 2-3. The power supply system is divided in two with a

separate 3.3V regulator for both EDBG, and for the Target section. The power supply block diagram for

revision 2 and 3 is shown below. The power switch has been redesigned to avoid voltage leakage at

power on. The DAC, LIN, and CAN connectors have been moved to ease mounting in production. The

RESET level-shifter has been redesigned to avoid leakage when target power is switched off.
