SLLSE76Q March 2011 – March 2024 TUSB7320 , TUSB7340
PRODUCTION DATA
This read-only register identifies the Device Serial Number for the TUSB73x0. The Device Serial Number is in the format of an IEEE defined 64-bit extended unique identifier (EUI-64). The EUI-64 consists of TI’s 24-bit company ID (called an OUI-24) plus a 40 bit extension identifier. TI’s OUI-24 is 080028h and is hardwired into bits 63:40 of the Device Serial Number Register. The TUSB73x0 has been assigned the range of 00 0000 0000h to 00 0FFF FFFFh for the 40-bit extension identifier. As such, bits 39:32 of the Device Serial Number Register are hardwired to 00h, and bits 31:0 of the Device Serial Number Register are defined by a value unique for each device.
