Other Parts Discussed in Thread: TUSB2046B

hi,

i intend to use the TUSB2046BIRHB with SOM based on AM335X.

regarding pins 5,6,26.

if the data lines are disabled the component is automatic bridge for up to 4 USB ports simultaneously?

what is the exact function of pins 5,6,26 and where do i connect them to the SOM (regular I/O, I2C....)?

can u give example of using the SUSPEND pin?

    hello Golan,

    EECLK (pin 5): EEPROM serial clock. When EXTMEM is high, the EEPROM interface is disabled. The EECLK  terminal is disabled and must be left floating (unconnected). When EXTMEM is low, EECLK acts as a 3-state serial clock output to the EEPROM with a 100-μA internal pulldown.

    EEDATA/ GANGED(pin 6): EEPROM serial data/power-management mode indicator. When EXTMEM is high, EEDATA/GANGED selects between ganged or per-port power overcurrent detection for the downstream ports. When EXTMEM is low, EEDATA/GANGED acts as a serial data I/O for the EEPROM and is internally pulled down with a 100-μA pulldown. This standard TTL input must not change dynamically during operation

    EXTMEM (pin 26): When EXTMEM is high, the serial EEPROM interface of the device is disabled. When EXTMEM is low, terminals 5 and 6 are configured as the clock and data terminals of the serial EEPROM interface, respectively.

    Also You can review the TUSB2046B Reference Schematic for a detailed implementation guide.
