Info - Revision

The Revision mode of the Info command reads back the silicon revision of the ATECC608A-TNGTLS. This information is hard coded into the device. This information may or may not be the same as what is read back in the Revision bytes shown in the Configuration zone.

Table 1. Input Parameters - Info Revision
Opcode (1 Byte)	Mode (1 Byte)	Param (2 Bytes)	Data (0 Bytes)	Description
0x30	0x00	0x00 00	—	Returns silicon revision

Table 2. Output Response - Info Revision
Name	Response	Description
Response	00 00 60 vv	Revision Info. 0x60 indicated ATECC608A-TNGTLS. vv is the most recent silicon version.

Note: The Output Response for the ATECC608A devices will be 0x00 0x00 0x60 0x02. The response for the ATECC608B devices will be 0x00 0x00 0x60 0x03. The device revision is the easiest way to determine which version of silicon you have. Over time the fourth byte for the ATECC608B could change if additional silicon enhancements are implemented.
