Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VSS | power_in | Ground reference for the device. |
| 2 | XO | output | 12MHz crystal oscillator output. |
| 3 | XI | input | 12MHz crystal oscillator input. |
| 4 | DM4 | bidirectional | USB D- signal for the 4th downstream port. |
| 5 | DP4 | bidirectional | USB D+ signal for the 4th downstream port. |
| 6 | DM3 | bidirectional | USB D- signal for the 3rd downstream port. |
| 7 | DP3 | bidirectional | USB D+ signal for the 3rd downstream port. |
| 8 | DM2 | bidirectional | USB D- signal for the 2nd downstream port. |
| 9 | DP2 | bidirectional | USB D+ signal for the 2nd downstream port. |
| 10 | DM1 | bidirectional | USB D- signal for the 1st downstream port. |
| 11 | DP1 | bidirectional | USB D+ signal for the 1st downstream port. |
| 12 | VDDR12 | power_out | 1.2V output from the 3.3V to 1.2V LDO. |
| 13 | VDD33 | power_in | 3.3V input for the 3.3V to 1.2V LDO (operating range 3.0 V to 3.6 V per Section 9.2). |
| 14 | REXT | input | USB PHY bias reference pin. |
| 15 | DMU | bidirectional | USB D- signal for the upstream port (the datasheet text reads D-; see review_required). |
| 16 | DPU | bidirectional | USB signal for the upstream port, labelled D- in the pin table (see review_required; likely D+). |
| 17 | SRST | input | System reset pin, pulled up by default. |
| 18 | VBUS_IN | input | USB VBUS facing port used to monitor VBUS power state; the chip starts function when VBUS_IN = 1. |
| 19 | PSELF | bidirectional | Bus power monitor distinguishing self-powered (high) from bus-powered (low) operation, default pull-up; can support DCP mode with VBUS connected. |
| 20 | VDD5 | power_in | 5V input for the LDO (VBUS range 3.0 V to 5.5 V per Section 9.2). |
| 21 | VDDR33 | power_out | 3.3V output from the 5V LDO. |
| 22 | DRV | bidirectional | LED control and charging hub enable, default pull-down; tied to GND for hub active/suspend indication, pulled high to enable BC1.2 charging mode. |
| 23 | LED1/EESCL | bidirectional | LED control for downstream ports 1 and 3, and EEPROM clock (SCL), default pull-down. |
| 24 | LED2/GLEDEN | bidirectional | LED control for downstream ports 2 and 4, and group LED indicator enable when pulled high to 3.3V, default pull-down. |
| 25 | PWRJ | bidirectional | Power switch enable for the 4 downstream ports in ganged power mode, active low, default pull-up. |
| 26 | OVCJ | bidirectional | Global over-current detection indicator for the 4 downstream ports, active low, default pull-up. |
| 27 | TEST / EESDA | bidirectional | Test mode enable and EEPROM data pin, default pull-up, active low; leave as no-connect or connect to EEPROM SDA for normal use. |
| 28 | VDD12 | power_in | 1.2V power input (operating range 1.08 V to 1.32 V per Section 9.2). |
