TUSB2036 and TUSB2077A EVM User's Guide

This document describes the main features and functionality of the TUSB2036 and TUSB2077Aevaluation module (EVM) boards. The 3-port TUSB2036 and 7-port TUSB2077A are USB 2.0 full-speedhubs.

The TUSB20xx EVM family is a collection of evaluation modules built to evaluate the operation of the TIfull-speed hubs. Each device has its own evaluation module which consist in one USB FS Upstream portand 3 or 7 USB FS downstream ports. The evaluation modules include all the required hardware tooperate the TI hub on all the possible configuration modes.

No special software, firmware, or drivers are required to operate these EVMs; any operating system withUSB stack support will support any of these hubs.

Hardware Description www.ti.com

4 Hardware DescriptionThis section contains descriptions of the external power source, bus power versus self power, voltageregulators, USB downstream power management, ESD protection, a reset signal, an external EEPROM,and external oscillator.

4.1 External Power SourceThe EVM can operate from a standard DC jack for connecting an external 5-V wall-wart. The wall-wartshould be rated for 5 V with at least a 2-A current rating. The tip of the DC jack has positive polarity. Awall-wart is not supplied with this evaluation module, leaving it capable of bus power mode by default. Inthis mode, only a maximum of 4-downstream ports are supported. If more than 4-downstream ports arerequired, a wall-wart must be used.

High-power USB devices require the use of the wall-wart as well.

4.2 Bus Power versus Self PowerThe EVM can be configured to operate off the USB cable power (VBUS) or a 5-V wall-wart.

The EVM uses the TPS2111 as a supervisory circuit to automatically switch from one source to another. Ifboth sources are present at the same time, the EVM will switch to use the external power source.

When the EVM is using the cable power, only low-power USB devices are supported, these are devicesthat draw no more than 100 mA from VBUS.

When the EVM is using the external power, high-power devices drawing up to 500 mA are supported onevery downstream port.

4.3 Voltage RegulatorThe TPS76333 is used to step down the 5-V source (cable or wall-wart) to a 3.3-V voltage rail required topower the TUSB20XX.

4.4 USB Downstream Power ManagementThe USB Specification requires a power management circuit when the USB downstream ports are goingto be actively attached or detached. The EVM uses the TPS2044B for power management, this circuitprovides the 5-V (VBUS) signal to each USB downstream port and it also works as an over-current andover-temperature supervisor. The TUSB20XX controls the TPS2044B by asserting the PWRON# signals.When a USB downstream port is drawing more than 500 mA from VBUS, the TPS2044B triggers an OC#signal to the hub and this de-asserts the corresponding PWRON# signal which, in turn, removes the 5-Vsignal from the specific downstream port. The TPS2044B cannot be used as a chip select fordownstream ports by controlling the state of the EN# and OE# signals. This is because when an over-current event is present the specification requires the USB host to decide whether or not to apply power tothe downstream port.

4.5 ESD ProtectionThe EVM implements ESD protection on all the USB ports using the SN75240.

4.6 ResetThe TUSB20XX requires a Reset signal at power up for proper operation, the Datasheet specifies thetiming requirements for the power-on Reset signal. The EVM implements this power-on reset by adding anRC circuit from the 3.3-V power rail to the RESET# input. The EVM also implements a Reset push buttonwhich can be used to bring the device to its default state at any time.

4.7 External EEPROMThe TUSB20xx hub is fully operational without any external EEPROM. The EVM; however, implements anoption to populate an external EEPROM to store a custom product ID (PID). If an external EEPROM isused, jumpers U10 and U22 on the TUSB2036 and jumpers U11 and U25 on the TUSB2077A EVM haveto be set accordingly. See Table 3 for configuration options.

4.8 External OscillatorThe TUSB20xx requires a clock input which may come from a crystal or an external oscillator. See thedevice datasheet (TUSB2036 - SLLS372, TUSB2077A - SLLS414) for more information about electricalspecs. The EVM implements a crystal oscillator circuit, by default, and it is equipped with a socket for anexternal oscillator. See Table 3 for configuration options.

5 LED IndicatorsLED descriptions for the TUSB2036 EVM are shown in Table 1 and the LED descriptions for theTUSB2077A EVM are shown in Table 2.
