TUSB2046IBVF

Texas Instruments · USB Converters · LQFP-32(7x7)

TUSB2046IBVF from Texas Instruments, in a LQFP-32(7x7). 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, paired with DM0 to form the upstream USB port.
2 DM0 bidirectional Root port USB differential data minus, paired with DP0 to form the upstream USB port.
3 VCC power_in 3.3-V supply voltage; recommended operating range is 3.0 V to 3.6 V for the TUSB2046B and 3.3 V to 3.6 V for the TUSB2046BI and TUSB2046I.
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 output (3-state) with a 100-µA internal pulldown when EXTMEM is low; it is disabled and must be left unconnected when EXTMEM is high.
6 EEDATA/GANGED bidirectional Serial EEPROM data I/O with a 100-µA internal pulldown when EXTMEM is low, or the GANGED power-management mode select when EXTMEM is high; this standard TTL input 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 output for downstream port 1, which cannot drive 5-V signals so external switches must accept 3.3-V inputs.
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 USB differential data minus for downstream port 1, paired with DP1.
12 DP1 bidirectional USB differential data plus for downstream port 1, paired with DM1.
13 PWRON2 output Active-low push-pull power-on/off control output for downstream port 2, which cannot drive 5-V signals so external switches must accept 3.3-V inputs.
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 USB differential data minus for downstream port 2, paired with DP2.
16 DP2 bidirectional USB differential data plus for downstream port 2, paired with DM2.
17 PWRON3 output Active-low push-pull power-on/off control output for downstream port 3, which cannot drive 5-V signals so external switches must accept 3.3-V inputs.
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 USB differential data minus for downstream port 3, paired with DP3.
20 DP3 bidirectional USB differential data plus for downstream port 3, paired with DM3.
21 PWRON4 output Active-low push-pull power-on/off control output for downstream port 4, which cannot drive 5-V signals so external switches must accept 3.3-V inputs.
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 USB differential data minus for downstream port 4, paired with DP4.
24 DP4 bidirectional USB differential data plus for downstream port 4, paired with DM4.
25 VCC power_in 3.3-V supply voltage; recommended operating range is 3.0 V to 3.6 V for the TUSB2046B and 3.3 V to 3.6 V for the TUSB2046BI and TUSB2046I.
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 Test terminal that must be tied to ground for normal 6-MHz operation, or may receive a 48-MHz clock source (no crystal) for 48-MHz input clock operation.
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 input with 50% duty cycle that drives the internal PLL generating the 48-MHz and 12-MHz clocks; an external oscillator output must not exceed 3.6 V TTL level.
31 TSTMODE input Test/mode terminal that must be tied to ground for 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 mode and low during normal operation.
