80 / 126 page ![]() Device identification STLUX 80/126 DocID027870 Rev 1 11 Device identification 11.1 Unique ID The STLUX family provides a 56-bit unique identifier code usable as a device identification number which can be used to increase the device security. The unique ID code is a frozen signature not alterable by user. The unique device identifier is ideally used by the application software and is suited for: Serial code Security keys in conjunction with cryptographic software to increase the embedded Flash code security Activating the secure boot sequence. 11.2 Device ID The STLUX family identification model is coded in the following register area and it cannot be altered by the user. Table 64. Unique ID register overview Address Option name Unique ID bits 76 5 4 3 2 1 0 48E0h UID0 LotNum [7:0] 48E1h UID1 LotNum [15:8] 48E2h UID2 LotNum [23:16] 48E3h UID3 WaferNum [4:0] Xcoord [7:5] 48E4h UID4 Xcoord [4:0] Ycoord [7:5] 48E5h UID5 Ycoord [4:0] LotNum [42:40] 48E6h UID6 LotNum [31:24] 48E7h UID7 LotNum [39:32] Table 65.
