Crypto Device - ATECC508A (U4)
The WINC1500 PICtail/PICtail Plus Daughter Board contains a ATECC508A Crypto
authentication device. The I
2
C pins required for interfacing with the ATECC508A
device is connected only to the PICtail Plus connector. The ATECC508A device is inter-
faced with the host MCU through 0R resistors, R22 and R23.
The 0R resistors are not mounted in the Rev 1 of the board and users need to solder
these pads. These resistors are mounted from the Rev 1.2 of the board. The revision
of the board could be found from the text in the bottom copper layer "04-10608 REV
X.X", where X.X indicates the revision of the board.
