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; 3.0 V to 3.6 V is the recommended range for TUSB2046B. |+| 4 | RESET | input | Active-low TTL input with hysteresis that must be asserted at power-up; a reset pulse of 100 µs to 1 ms is recommended after VCC reaches 90%, and the clock must be active during the last 60 µs of the reset window. |+| 5 | EECLK | output | EEPROM serial clock, a 3-state output with a 100-µA internal pulldown when EXTMEM is low; it must be left floating when EXTMEM is high. |+| 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; it is a TTL input that must not change dynamically during operation. |+| 7 | GND | power_in | Ground; must be tied to ground for proper operation. |+| 8 | BUSPWR | input | Power source indicator: pull to 3.3 V for bus-powered mode or pull low for self-powered mode; must not change dynamically during operation. |+| 9 | PWRON1 | output | Active-low push-pull power-on/off control output; the external power switch must accept 3.3-V inputs because the output cannot drive 5-V signals. |+| 10 | OVRCUR1 | input | Active-low overcurrent input with noise filtering; in ganged mode all OVRCUR terminals must be tied together. |+| 11 | DM1 | bidirectional | Downstream USB differential data minus, paired with DP1 for downstream port 1. |+| 12 | DP1 | bidirectional | Downstream USB differential data plus, paired with DM1 for downstream port 1. |+| 13 | PWRON2 | output | Active-low push-pull power-on/off control output for downstream port 2; the external power switch must accept 3.3-V inputs. |+| 14 | OVRCUR2 | input | Active-low overcurrent input for downstream port 2 with noise filtering; in ganged mode all OVRCUR terminals must be tied together. |+| 15 | DM2 | bidirectional | Downstream USB differential data minus, paired with DP2 for downstream port 2. |+| 16 | DP2 | bidirectional | Downstream USB differential data plus, paired with DM2 for downstream port 2. |+| 17 | PWRON3 | output | Active-low push-pull power-on/off control output for downstream port 3; the external power switch must accept 3.3-V inputs. |+| 18 | OVRCUR3 | input | Active-low overcurrent input for downstream port 3 with noise filtering; in ganged mode all OVRCUR terminals must be tied together. |+| 19 | DM3 | bidirectional | Downstream USB differential data minus, paired with DP3 for downstream port 3. |+| 20 | DP3 | bidirectional | Downstream USB differential data plus, paired with DM3 for downstream port 3. |+| 21 | PWRON4 | output | Active-low push-pull power-on/off control output for downstream port 4; the external power switch must accept 3.3-V inputs. |+| 22 | OVRCUR4 | input | Active-low overcurrent input for downstream port 4 with noise filtering; in ganged mode all OVRCUR terminals must be tied together. |+| 23 | DM4 | bidirectional | Downstream USB differential data minus, paired with DP4 for downstream port 4. |+| 24 | DP4 | bidirectional | Downstream USB differential data plus, paired with DM4 for downstream port 4. |+| 25 | VCC | power_in | 3.3-V supply voltage; 3.0 V to 3.6 V is the recommended range for TUSB2046B. |+| 26 | EXTMEM | input | When high, disables the serial EEPROM interface; when low, pins 5 and 6 act as the EEPROM clock and data terminals. |+| 27 | TSTPLL/48MCLK | bidirectional | Production test terminal that must be tied to ground for normal 6-MHz operation; a 48-MHz clock source (no crystal) may be connected here for 48-MHz input clock operation. |+| 28 | GND | power_in | Ground; must be tied to ground for proper operation. |+| 29 | XTAL2 | output | 6-MHz crystal output; this terminal must be left open when an oscillator drives XTAL1. |+| 30 | XTAL1 | input | 6-MHz crystal input with 50% duty cycle that feeds the internal PLL; when driven by an oscillator the 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 for external logic power-down; it is high during suspend and low during normal operation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | LQFP-32(7x7) |+| Category | Interface |+| Pins | 32 |++## CAD (KiCad official)++- Symbol: `TUSB2046BVF`+- Footprint: `Package_QFP:LQFP-32_7x7mm_P0.8mm`+- 3D model: LQFP-32(7x7) (KiCad packages3D, STEP)+- 3D model files: `tusb2046bvf-etched.step` / `tusb2046bvf-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready);
