TUSB9260 DEMO Board Block Diagram
Figure 1 represents the block diagram of the TUSB9260 DEMO Board. The board is designed to be
powered from either a 12-V DC wall-wart (not supplied) or via USB cable power.

12-V DC Jack
The DEMO Board can operate from a standard DC jack for connecting an external 12-V wall-wart. The
wall-wart should be rated for 12 V with at least a 2-A current rating. The tip of the DC jack has positive
polarity. A wall-wart is not supplied with this reference design demonstration module, leaving it capable of
bus power mode by default. In this mode, only Solid State Drives will work. If other higher current hard
drives are to be used a wall-wart will have to be used.

Cable Power vs. Self Power
The DEMO Board can be configured to operate off of cable power or use the 12-V wall-wart. To configure
the board to use cable power jumper J4 must have a jumper placed across pins 1 and 2. When configured
for cable power mode only 5-V and 3.3-V are available at the SATA connector. Therefore only SATA
devices such as SSD drives may operate in this mode.
For self power mode J4 must have a jumper placed across pins 2 and 3. In this mode any SATA device
can operate since 12 V, 5 V, and 3.3 V are available at the SATA connector.

Power Switch
The DEMO Baord uses a TI TPS2561 power switch. This switch serves two purposes. It limits the amount
of in-rush current on VBUS and it allows power to the SATA connector to be switched via the TUSB9260.
The switch is controlled via GPIO10 from the TUSB9260 and power faults can be monitored by GPIO11.
By default the DEMO Board is configured to always apply power to the SATA connector and power faults
are not monitored.

3.3-V, 1.8-V, and 1.1-V Regulator
The DEMO Board utilizes a TI TPS650061 regulator to power the TUSB9260 and associated circuitry.
1 Push Button Reset
Connected to the TPS650061 is a push button (SW2) that can be used to reset the TUSB9260 to its
default state. When pressed the global reset terminal (GRST#) on the TUSB9260 will be driven low.

SPI
The TUSB9260 supports a SPI interface connected to a SPI flash device. The flash device is used to hold
the firmware for the TUSB9260.
For normal SPI operation a jumper on J13 must be populated. For reprogramming of the SPI flash device
it may be necessary to temporally remove J13. Refer to the TUSB9260 Flash Burner User Guide
(SLLU125) for more information about programming the SPI flash.

Crystal or Oscillator Support
The TUSB9260 DEMO can support either a crystal or oscillator reference clock. By default the board is
configured to use a 25-MHz crystal. To use an oscillator R23 and R37 need to be populated with a 0-ohm
resistor. C17 and C19 need to be de-populated. The crystal or oscillator should be rated for 1.8 V with
PPM of ±100 or better. The frequency of the clock is configurable via resistors R10-R13. Table 1 shows
how to populate resistors R10-R13 for desired clock frequency.

GPIOs/LEDs/PBUTTON
1 GPIO LEDs
Each GPIO is connected to an LED on the DEMO Board. The LEDs are located along the top side of the
board (D1 – D8). The LEDs are for test purposes and can be used to indicate device operational states.
This is firmware dependent.
2 PWM LEDs
Each PWM is connected to an LED (D3 and D6) on the DEMO Board. PWM LEDs are for test purposes
and can be used to indicate hard drive activity or USB activity. This is firmware dependent.
3 GPIO Push Button
There is one GPIO configurable push button (SW1) on the DEMO Board. This push button is connected to
GPIO3. This is firmware dependent.

Troubleshooting Tips for Windows
If the hard drive can be seen in Device Manager but does not show up in Windows Explorer (as seen
below) you may need to partition and format the hard drive. This is typical of a new or corrupted hard
drive.
