Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | DP0 | bidirectional | Root port USB differential data plus; DP0 paired with DM0 forms the upstream USB port. |+| 2 | DM0 | bidirectional | Root port USB differential data minus; DM0 paired with DP0 forms the upstream USB port. |+| 3 | VCC | power_in | 3.3-V supply voltage; recommended range is 3.3 V to 3.6 V for TUSB2046BI/TUSB2046I (3 V to 3.6 V for TUSB2046B). |+| 4 | RESET | input | Active-low TTL input with hysteresis that must be asserted at power-up; a 100 µs to 1 ms reset pulse is recommended after VCC reaches 90%, and the clock must be active during the last 60 µs of the reset window. |+| 5 | EECLK | tri_state | EEPROM serial clock 3-state output with a 100-µA internal pulldown when EXTMEM is low; when EXTMEM is high the terminal is disabled and must be left unconnected. |+| 6 | EEDATA/GANGED | bidirectional | When EXTMEM is high it selects ganged or per-port overcurrent detection; when EXTMEM is low it is the EEPROM serial data I/O with a 100-µA internal pulldown, and as a standard TTL input it must not change dynamically during operation. |+| 7 | GND | power_in | Ground terminal that must be tied to ground for proper operation. |+| 8 | BUSPWR | input | Active-high power source indicator that must be pulled to 3.3 V for bus-powered mode or pulled low for self-powered mode, and must not change dynamically during operation. |+| 9 | PWRON1 | output | Active-low push-pull power-on/off control for downstream port 1; external power switches must accept 3.3-V inputs because the output cannot drive 5-V signals. |+| 10 | OVRCUR1 | input | Active-low overcurrent input with noise filtering for downstream port 1; in ganged mode all OVRCUR terminals must be tied together. |+| 11 | DM1 | bidirectional | Downstream port 1 USB differential data minus, paired with DP1. |+| 12 | DP1 | bidirectional | Downstream port 1 USB differential data plus, paired with DM1. |+| 13 | PWRON2 | output | Active-low push-pull power-on/off control for downstream port 2; external power switches must accept 3.3-V inputs because the output cannot drive 5-V signals. |+| 14 | OVRCUR2 | input | Active-low overcurrent input with noise filtering for downstream port 2; in ganged mode all OVRCUR terminals must be tied together. |+| 15 | DM2 | bidirectional | Downstream port 2 USB differential data minus, paired with DP2. |+| 16 | DP2 | bidirectional | Downstream port 2 USB differential data plus, paired with DM2. |+| 17 | PWRON3 | output | Active-low push-pull power-on/off control for downstream port 3; external power switches must accept 3.3-V inputs because the output cannot drive 5-V signals. |+| 18 | OVRCUR3 | input | Active-low overcurrent input with noise filtering for downstream port 3; in ganged mode all OVRCUR terminals must be tied together. |+| 19 | DM3 | bidirectional | Downstream port 3 USB differential data minus, paired with DP3. |+| 20 | DP3 | bidirectional | Downstream port 3 USB differential data plus, paired with DM3. |+| 21 | PWRON4 | output | Active-low push-pull power-on/off control for downstream port 4; external power switches must accept 3.3-V inputs because the output cannot drive 5-V signals. |+| 22 | OVRCUR4 | input | Active-low overcurrent input with noise filtering for downstream port 4; in ganged mode all OVRCUR terminals must be tied together. |+| 23 | DM4 | bidirectional | Downstream port 4 USB differential data minus, paired with DP4. |+| 24 | DP4 | bidirectional | Downstream port 4 USB differential data plus, paired with DM4. |+| 25 | VCC | power_in | 3.3-V supply voltage; recommended range is 3.3 V to 3.6 V for TUSB2046BI/TUSB2046I (3 V to 3.6 V for TUSB2046B). |+| 26 | EXTMEM | input | When high, the serial EEPROM interface is disabled; when low, pins 5 and 6 become the EEPROM clock and data terminals. |+| 27 | TSTPLL/48MCLK | bidirectional | Test terminal that must be tied to ground for normal 6-MHz operation; for 48-MHz operation a 48-MHz clock source (no crystal) can be connected to this input. |+| 28 | GND | power_in | Ground terminal that must be tied to ground for proper operation. |+| 29 | XTAL2 | output | 6-MHz crystal output that must be left open when an oscillator drives XTAL1. |+| 30 | XTAL1 | input | 6-MHz crystal or oscillator input with 50% duty cycle, from which the internal PLL generates the 48-MHz and 12-MHz clocks; an oscillator TTL output must not exceed 3.6 V. |+| 31 | TSTMODE | input | Test/mode terminal that must be tied to ground for normal 6-MHz operation or to 3.3-V VCC for 48-MHz operation. |+| 32 | SUSPND | output | Active-high suspend status output that is high during suspend mode and low during normal operation. |+| 33 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VQFN-32(5x5) |+| Category | Interface |+| Pins | 33 |++## CAD (KiCad official)++- Symbol: `TUSB2046BIRHBTG4`+- Footprint: `Package_DFN_QFN:QFN-32-1EP_5x5mm_P0.5mm_EP3.3x3.3mm`+- 3D model: VQFN-32(5x5) (KiCad packages3D, STEP)+- 3D model files: `tusb2046birhbtg4-etched.step` / `tusb2046birhbtg4-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready);
