I'm building a custom Arduino MKRZero board. I'm sourcing the components from Digikey. I'm stuck on the ATECC508A authentification IC.
The problem is that the Arduino schematic mentions "ATECC508A-MAHDA" for the IC. Datasheet of the component says it communicates through I2C. There is no more stock for this IC on Digikey but the ATECC508A-SSHAW, ATECC508A-SSHCZ and ATECC508A-MAHCZ are available.
Datasheet (P26) of the component says "SSH" and "MAH" stand for the package options, "CZ" and "DA" stand for the I/O types : "CZ" = Single Wire Interface ; "DA" = I2C. But nothing in the datasheet about "AW" (ATECC508A-SSHAW). I need a I2C IC but I don't know if this one (ATECC508A-SSHAW) is I2C or Single Wire.
