Table 1 lists the changes in the pin definitions of the TUSB211 and TUSB216I devices, and highlights pin configurations that may require change when using the TUSB216I to replace the TUSB211 in an existing system.
| Pin | TUSB211 | TUSB216I | Schematic and BOM Change Notes |
|---|---|---|---|
| 1 | D1M | D1M | No change required |
| 2 | D1P | D1P | No change required |
| 3 | TEST | SDA | GPIO mode: no change required |
| I2C mode: add a 4.7-kΩ pullup to 1.8 V or 3.3 V; connect to master SDA. | |||
| 4 | CD | SCL/CD | No change required, GPIO Mode: Recommended to connect the pin to a test point on the PCB. |
| I2C mode: add a 4.7-kΩ pullup to 1.8 V or 3.3 V; connect to master SCL. | |||
| 5 | RSTN | RSTN | No change required |
| 6 | EQ |
BOOST |
BOM: pulldown resistor value may need to change for optimal tuning, optional. |
| 7 | D2P | D2P | No change required |
| 8 | D2M | D2M | No change required |
| 9 | ENA_HS | RX_SEN/ENA_HS |
No Change required. Mid RX_SEN setting is selected automatically if the pin is left disconnected. Schematic (Optional): resistor options can be added for RX_SEN tuning. Recommend connecting ENA_HS pin to a test point on the PCB. |
| 10 | GND | GND | No change required |
| 11 | VREG | CDP_ENZ | No change required If CDP is not in use. |
| 12 | VCC | VCC | No change required |
