Part Number: TUSB7320
Other Parts Discussed in Thread: USB2ANY
Dear TI Support Team,
I am using the TUSB7320 USB 3.0 xHCI host controller with the optional external I2C EEPROM (24xxseries) to customize Vendor ID / Device ID and port configuration.
In the current datasheet SLLSE76Q (Rev. Q, March 2024), Section 8 “Register Maps” only contains Table 8.1. PCI Configuration Register Map, which describes the PCI configuration space at offsets 000h0FCh.
The older E2E answers and documentation refer to an “EEPROM register map (Table 3.1)” in the datasheet, but this table does not appear anywhere in Rev. Q, and there is no description of the EEPROM byte layout (offsets for Vendor ID, Device ID, descriptors, port config, etc.).
1.Could you please provide:The complete EEPROM register map for TUSB7320/TUSB73x0 (byte offsets and field definitions), or An older datasheet revision or application note where this EEPROM map is documented,
2.or A reference EEPROM image and description of which bytes correspond to Vendor ID, Device ID, and any other configurable options.I plan to program the EEPROM externally over I2C using a USB2ANY style programmer, so I only need the correct format and field map; the protocol itself is already clear from section 6.4.1 (TwoWire SerialBus Interface).
3.Without this EEPROM map, it is not possible to safely generate the correct contents for the external EEPROM on TUSB7320.
Thank you for your support.
