TUSB2036 SLLS372F – MARCH 2000 – REVISED SEPTEMBER 2013 www.ti.com DESCRIPTION The TUSB2036 hub is a 3.3-V CMOS device that provides up to three downstream ports in compliance with the USB 2.0 specification. Because this device is implemented with a digital state machine instead of a microcontroller, no firmware programming is required. Fully-compliant USB transceivers are integrated into the ASIC for all upstream and downstream ports.

TUSB2036 SLLS372F – MARCH 2000 – REVISED SEPTEMBER 2013 www.ti.com TERMINAL FUNCTIONS TERMINAL NAME BUSPWR DM0 NO. I/O 8 I DESCRIPTION Power source indicator. BUSPWR is an active-low input that indicates whether the downstream ports source their power from the USB cable or a local power supply. For the bus-power mode, this terminal must be pulled low, and for the self-powered mode, this terminal must be pulled to 3.3 V. Input must not change dynamically during operation.

TUSB2036 www.ti.com SLLS372F – MARCH 2000 – REVISED SEPTEMBER 2013 TERMINAL FUNCTIONS (continued) TERMINAL NAME VCC NO. I/O 3, 25 DESCRIPTION 3.3-V supply voltage XTAL1/CLK48 30 I Crystal 1/48-MHz clock input. When MODE is low, XTAL1/CLK48 is a 6-MHz crystal input with 50% duty cycle. An internal APLL generates the 48-MHz and 12-MHz clocks used internally by the ASIC logic. When MODE is high, XTAL1/CLK48 acts as the input of the 48-MHz clock and the internal APLL logic is bypassed.

TUSB2036 www.ti.com SLLS372F – MARCH 2000 – REVISED SEPTEMBER 2013 USB Design Notes The following sections provide block diagram examples of how to implement the TUSB2036 device. Note, even though no resistors are shown, pullup, pulldown, and series resistors must be used to properly implement this device. Figure 6 is a block diagram example of how to connect the external EEPROM if a custom product ID and vendor ID are desired. Figure 7 is an example of how to generate the 6-MHz clock signal.

TUSB2036 SLLS372F – MARCH 2000 – REVISED SEPTEMBER 2013 www.ti.com Programming the EEPROM An SGS Thompson M93C46 EEPROM, or equivalent, stores the programmable VID and PID. When the EEPROM interface is enabled (EXTMEM = 0), the EECLK and EEDATA are internally pulled down (100 μA) inside the TUSB2036. The internal pulldowns are disabled when the EEPROM interface is disabled (EXTMEM = 1). The EEPROM is programmed with the three 16-bit locations as shown in Table 2.

TUSB2036 SLLS372F – MARCH 2000 – REVISED SEPTEMBER 2013 www.ti.com Bus-Powered Hub, Ganged-Port Power Management When used in bus-powered mode, the TUSB2036 supports up to four downstream ports by controlling a TPS2041 device which is capable of supplying 100 mA of current to each downstream port. Bus-powered hubs must implement power switching to ensure current demand is held below 100 mA when the hub is hot-plugged into the system.

TUSB2036 www.ti.com SLLS372F – MARCH 2000 – REVISED SEPTEMBER 2013 Self-Powered Hub, Individual-Port Power Management In a self-powered configuration, the TUSB2036 can be implemented for individual-port power management when used with two TPS2044 because it is capable of supplying 500 mA of current to each downstream port and can provide current limiting on a per port basis.
PAGE 14
TUSB2036 SLLS372F – MARCH 2000 – REVISED SEPTEMBER 2013 www.ti.com Self-Powered Hub, Ganged-Port Power Management The TUSB2036 can also be implemented for ganged-port power management in a self-powered configuration. The implementation is very similar to the bus-powered example with the exception that a self-powered port supplies 500 mA of current to each downstream port. The overcurrent protection can be provided by a TPS2044 quad device or a TPS2024 single power switch. TUSB2036 Upstream Port 1.
