| 10 | VDDA33 | power_in | 3.3V analog power supply. |
| 11 | TEST | passive | Test pin; must be treated as no-connect or connected to ground with no traces routed to this pin. |
| 12 | PRTPWR1 | output | Port 1 USB power enable output (12mA source); dual-function as battery charging strap option when strapped high via resistor. |
| 13 | OCS_N1 | input | Port 1 over-current sense input from external current monitor; active-low indicates over-current condition on port 1. |
| 14 | CRFILT | passive | Core regulator filter capacitor connection; optionally connect 0.1µF low-ESR capacitor to VSS or leave unconnected. |
| 15 | VDD33 | power_in | 3.3V digital power supply. |
| 16 | PRTPWR2 | output | Port 2 USB power enable output (12mA source); dual-function as battery charging strap option when strapped high via resistor. |
| 17 | OCS_N2 | input | Port 2 over-current sense input from external current monitor; active-low indicates over-current condition on port 2. |
| 18 | PRTPWR3 | output | Port 3 USB power enable output (12mA source); dual-function as battery charging strap option when strapped high via resistor. |
| 19 | OCS_N3 | input | Port 3 over-current sense input from external current monitor; active-low indicates over-current condition on port 3. |

| 22 | SDA | bidirectional | I2C/SMBus serial data line with open-drain output and Schmitt trigger input (12mA sink); dual-function as non-removable port 1 strap pin (NON_REM1). |
| 23 | VDD33 | power_in | 3.3V digital power supply. |
| 24 | SCL | bidirectional | I2C/SMBus serial clock line with open-drain output and Schmitt trigger input (12mA sink); dual-function as configuration select pin 0 (CFG_SEL0) latched on RESET_N negation. |
| 25 | HS_IND | output | Hi-speed upstream port indicator output (12mA source); driven high for HS connection, low for FS; dual-function as configuration select pin 1 (CFG_SEL1) latched on RESET_N negation. |
| 26 | RESET_N | input | Active-low reset input with Schmitt trigger; system can reset the device by driving low; minimum active-low pulse is 1µs after all supplies within operating range. |
| 27 | VBUS_DET | input | Upstream VBUS power detection input; detects upstream bus power state to control internal D+ pull-up assertion; use 2:1 voltage divider (two 100kΩ resistors) for detachable hubs. |
| 28 | SUSP_IND | output | Active/suspend status LED output; negated (low) when unconfigured or suspended, asserted (high) when configured and active; multi-function with LOCAL_PWR/NON_REM0. |
