Titanium Ti60 F225 Development Kit User Guide
The Titanium Ti60 F225 Development Board provides three multi-purpose 0.8 mm high-
speed ground plane sockets. These sockets can be used for GPIO, MIPI CSI-2 TX/RX, and
LVDS TX/RX. The board includes two USB type-C ports, one for USB 3.0 interface and the
other for the FTDI interface.
The FTDI FT4232H module has four channels to support the following interfaces:
• SPI —FTDI interface 0
• FPGA JTAG —FTDI interface 1
• FPGA UART —FTDI interface 2
• USB 3.0 chip UART —FTDI interface 3
The FTDI module receives the Ti60 configuration bitstream from a USB host and writes to
the Ti60 FPGA in SPI passive configuration. You can write a configuration bitstream to the
on-board SPI NOR flash memory through JTAG with the JTAG SPI Flash Loader Core.
Additionally, it supports a UART interface to the Ti60 and the USB 3.0 chip.
The SPI NOR flash memory stores the configuration bitstream. The Ti60 device accesses this
configuration bitstream when it is in active configuration mode (default).

Power On
To turn on the development board, turn on switch SW4. The 12 V DC power is input to
the on-board regulators to generate the required 3.3 V, 2.5 V, 1.8 V, 1.5 V, and 1.2 V for
components on the board. When these voltages are up and stable, the power-good LED, D22
illuminates, giving you a visual confirmation of the status.
Reset
The Ti60F225C4 device is typically brought out of reset with the
CRESET
signal. Upon
power up, the Ti60F225C4 device is held in reset until
CRESET
toggles high-low-high.
Note: You can manually assert the high-low-high transition with pushbutton switch SW3.
CRESET
has a pull-up resistor. When you press SW3, the board drives
CRESET
low; when
you release SW3, the board drives
CRESET
high. Thus, a single press of SW3 provides the
required high-low-high transition.
After toggling
CRESET
, the Ti60F225C4 device goes into configuration mode and reads
the device configuration bitstream from the flash memory. When configuration completes
successfully, the device drives the
CDONE
signal high.
CDONE
is connected to a green LED
(D15), which turns on when the Ti60F225C4 device enters user mode.
