1 Overview
1.1 What is the TUSB1004EVM?
The TUSB1004EVM is a PCB created to help for customers to evaluate the TUSB1004. The EVM has two
Mirco-B USB receptacles and a stacked dual port USB-A receptacle. The user of the EVM can insert a standard
Micro-B USB cable into the TUSB1004EVM board then conenct the cable to a motherboard or system. The user
can then insert an USB device directly or through an standard USB cable into the USB-A receptacle side of the
EVM board.
1.2 What is Included in the TUSB1004EVM?
The following are the major components of the EVM:
• TUSB1004 device
• Two Micro-B USB receptacle
• Dual Port USB-A receptacle
• Headers for configurating various TUSB1004 features.

2 Hardware Configuration
2.1 Power
The EVM board can be powered from either Micro-B VBUS pin or from an external power supply through the
barrel jack (J4). The EVM defaults to being powered from a Micro-B Receptacle VBUS (J3).
If powering the EVM from barrel jack, make sure R46 is unpopulated. When removed, a jumper will need to be
placed across JMP13 pins 1 and 2.
Note
Limit VBUS voltage and voltage from barrel jack to no more than 6 V.
2.2 Configuration Jumpers
Multiple jumpers are provided on the EVM for configuration of TUSB1004 and also for probe points.
Following is a list of 4-level jumpers which are used to configure the TUSB1004: JMP3, JMP4, JMP5, JMP6,
JMP7, JMP8, JMP9, and JMP10. The jumper position to select between the different levels is detailed in 4-Level
Configuration Jumper Settings Table.
Note
4-level pins are sampled on rising edge of the EN pin. Therefore, a change in any 4-level pin state will
not be applied until after the EN pin is toggled from low to high.

2.5 Local I2C Access
Access to TUSB1004s local I2C signals is provided through the JMP1 and JMP2 connectors. The TUSB1004
supports either 1.8 V and 3.3 V LVCMOS levels. The TUSB1004 VIO_SEL pin (JMP9) is used to select which
voltage level is used. It is important that the I2C signalling levels meet the TUSB1004 LVCMOS levels when I2C
interface is accessed through the connector.
When the MODE pin (JMP10) is floating, TUSB1004 will be enabled for I2C mode. The TUSB1004 I2C target
address is determined by sampled state of SSEQ0/A0 (JMP3) and SSEQ1/A1 (JMP4).
A standalone external I2C host can be connected for debug and control purposes. An example of an external
I2C Host controller is the Total Phase Aardvark I2C/SPI Host Adapter (Total Phase Part#: TP240141).

3 Quick Start Guide
The following instructions assume the EVM is configured for pin-strap mode and is powered from J3 VBUS.
1. Insert a Micro-B USB cable into J3 on the EVM. Connect the other end of the USB cable to the motherboard.
2. Insert a USB device or USB cable into the lower USB-A receptable of the EVM.
3. The USB device should enumerate. If the USB device does not enumerate, then check that VBUS is at the
appropiate level at D1 pin 1.
4. Insert a Micro-B USB cable into either J1 on the EVM. Connect the other end of the USB cable to the
motherboard.
5. Insert a USB device or USB cable into the upper USB-A receptable of the EVM.
6. The USB device should enumerate. If the USB device does not enumerate, then check that VBUS is at the
appropiate level at D2 pin 1.
The following instructions assume the EVM is configured for the I2C mode and is powered from the barrel jack.
1. Insert +5 V DC power source into the barrel jack (J4).
2. Configure the TUSB1004 through the I2C interface (JMP1 and JMP2).
3. Insert a Micro-B USB cable into either J3 or J1 on the EVM. Connect the other end of the USB cable to the
motherboard.
4. Insert a USB device or USB cable into either USB-A receptable of the EVM. Be sure to connect that the USB
device/cable into the correposding USB-A receptacle (J3 = lower receptaclce, J1 = upper receptacle)
5. The USB device should enumerate. If the USB device does not enumerate, check that VBUS is at the
appropiate level at the correcpsoding USB-A receptacle, pin1 of D1 or D2.
