3.2 DEMO_FX3_U3V_CAM01 baseboard design details
The DEMO_FX3_U3V_CAM01 baseboard consists of the FX3 silicon (CYUSB3014-BZXI), USB-C connector,
SuperSpeed MUX, and SPI flash. The board is bus-powered and uses a 19.2-MHz crystal for operation. The
development board provides convenient access to FX3 interfaces, such as GPIOs, I2C, SPI, and JTAG. The two
40-pin headers (on the reverse PCB side in Figure 3) provide FX3 signals to connect to external boards using the
GPIO interface. Note that for convenience, the headers have long pins that extend above the top side of the PCB
for use as test points or attachment to mating connectors. All I/O signals, which include the 32-bit data bus, 13
control lines, and a 100-MHz clock, are available to connect to external devices such as FPGAs, CPLDs, image
sensors, or microcontrollers.
The baseboard contains the following key components:
3.2.1 USB connector (J1)
The FX3 capture kit provides one USB 3.0 Type-C receptacle that brings out FX3 USB signals. This receptacle
accepts a Type-C connection, and the other end of the cable connects to a USB host PC via either a Type-A or a
Type-C port as well. A SuperSpeed USB-C cable is included in the kit. Use this port to test FX3 applications that
communicate with a host PC. Using the Type-C interface allows access to FX3 debug interface using serial
terminal messages.
3.2.2 Jumpers and switches
Jumper (J2): This is a power ON jumper. When closed, it allows USB VBUS for powering the board.
J2 close: Power ON (Default)
J2 open: Power OFF
Power switch (SW1): This is used to switch the add-on board power from 1.8 V to 3.3 V and vice-versa. This
allows compatibility with FX3 camera kit interconnect modules, which typically require 1.8 V. The camera add-
on board supplied with this kit can operate at both 1.8 V and 3.3 V; however, to connect an external Raspberry
Pi MIPI camera board, 3.3 V is required.
SW1 ON: 3.3 V (Default)
SW1 OFF: 1.8 V
Reset switch (SW2): Reboots the silicon. Press the switch and release to boot from the selected mode set by
SW3.
Mode selection switch (SW3): Selects the mode in which FX3 has to boot upon reset or power ON. The FX3
camera kit can boot in two modes based on the position of this switch.
Table 2 Boot modes

SW3.1 ON
To program the device, set SW3 in USB mode. After programing, setting the mode switch in SPI mode and
rebooting the device allows FX3 to boot from the SPI flash.
User switch (SW4): Allows to achieve user-defined functions such as still capture. Pressing this switch sends an
I2C command to FX3.

EZ-USB™ FX3 camera kit system design
3.2.3 Baseboard power supply
The baseboard consists of three regulators. Each power rail has corresponding test points on the board for
probing. Make sure no external voltages are applied at the test points as it may permanently damage the kit
functionality.
3.2.3.1 5 V to 3.3 V regulator (U1)
This is an LDO that provides a 3.3 V output at 1 A. TLE4284DVATMA1 from Infineon Technologies is used on this
board.
3.2.3.2 5V to 1.2 V regulator (U6)
This is a buck regulator that provides 1.2 V for powering the FX3 core. It also provides power to the FPGA present
on camera add-on board. IR3883MTRPBF from Infineon Technologies is used on board.
3.2.3.3 5V to 1.8 V / 3.3 V regulator (U8)
This is an LDO that provides a 1.8 V or 3.3 V output at 1 A. This regulator features a switch SW1 that changes the
output voltage based on the switch status.
Mode 1: SW1 = OFF →VOUT = 1.8 V
Mode 2: SW1 = ON → VOUT = 3.3 V
TLE4284DVATMA1 from Infineon Technologies is used on this board.
3.2.4 FX3 (U3)
This is a USB 3.1 Gen 1 SuperSpeed controller with a 32-bit ARM926EJ core CPU and 512 kB embedded SRAM. It
supports UVC, UAC, U3V, and USB vendor class protocols. With GPIF II of 8-, 16-, 24-, and 32-bit data bus at
100 MHz, FX3 supports slave FIFO and parallel camera interface features. It has dedicated interfaces for SPI Flash
and I2C. FX3 supports selectable clock input frequencies at 19.2, 26, 38.4, and 52 MHz. Additionally, a dedicated
19.2 MHz crystal input support is also available. It is a 121-ball, 10- × 10-mm, 0.8-mm pitch Pb-free ball grid array
(BGA).
3.2.5 SPI flash (U7)
The kit configuration is stored on the 32-Mbit SPI flash. After power ON, FX3 fetches the required details from the
configuration image, stores it in its RAM and starts executing from it.
3.2.6 Interface/GPIO connectors (J4, J5)
The baseboard has two 20-pin interfaces/GPIO female connectors. All the signals required for interfacing FX3
with external add-on modules are routed to the connectors. Pin 5 of J4 in the connector is removed (i.e., cut) to
polarise the connector to avoid connecting the add-on boards in incorrect orientation.
Note: Do not connect any external voltage source to these pins as it may permanently damage the kit.
The pins are available only for probing purpose.
3.2.7 Crystal (Y1)
FX3 needs a 19.2-MHz crystal to generate the clock for its operation.

EZ-USB™ FX3 camera kit system design
3.2.8 Reset switch (SW2)
The reset switch (SW2) is provided for debug purpose. The RC circuit provides a clean reset signalevery time after
power up. The RC circuit formed by R1 and C72 gives a 10-ms pulse width because it assumes the worst 3.3 V
supply ramp up time and FX3 crystal POR reset time. On pressing SW2, FX3 starts rebooting based on the mode
selection switch SW3.
3.2.9 LEDs (LED1, LED2, LED3)
•LED1 (power ON LED) is a GREEN color LED used for 3.3-V power supply indication
•LED2 is a RED color LED to indicate fault on VBUS
•LED3 is a BLUE color application-driven user LED connected to GPIO_4 of FX3
3.3 DEMO_FX3_U3V_CAM01 camera add-on board design details
3.3.1 Add-on board power supply
The camera add-on board consists of three regulators. Each power rail has corresponding test points on board
for probing. Make sure no external voltages are applied at the test points as it may permanently damage the kit
functionality.
3.3.1.1 3.3 V to 1.5 V regulator (U3)
This is an LDO that generates 1.5 V from 3.3 V coming from the baseboard. TLS205B0LDVXUMA1 from Infineon
Technologies is used on the board. It is rated to provide maximum current of 300 mA.
3.3.1.2 3.3 V to 2.5 V regulator (U1)
This is an LDO that generates 2.5 V from 3.3 V coming from the baseboard. TLS205B0LDVXUMA1 from Infineon
Technologies is used on the board. It is rated to provide maximum current of 300 mA.
3.3.1.3 3.3 V to 2.8 V regulator (U5)
This is an LDO that generates 2.8 V from 3.3 V coming from the baseboard. TLS205B0LDVXUMA1 from Infineon
Technologies is used on the board. It is rated to provide maximum current of 300 mA.
3.3.2 Crosslink FPGA (U2)
The camera add-on board uses CrossLink FPGA from Lattice Semiconductor. It is a programmable video
bridging device that supports a variety of protocols and interfaces for mobile image sensors and displays.
CrossLink supports video interfaces including MIPI DPI, MIPI DBI, CMOS camera and display interfaces,
OpenLDI, FPD-Link, FLATLINK, MIPI D-PHY, MIPI CSI-2, MIPI DSI, SLVS200, subLVDS, HiSPi, and more.
This kit uses the two MIPI CSI-2 interface ports of the CrossLink FPGA to communicate with the onboard camera
module and external camera module. The FPGA converts the received MIPI signals to a 16-bit parallel interface
thus allowing FX3 to communicate with the image sensors / camera module directly. This kit uses the 80-ball
ctfBGA package with 37 I/Os.

3.3.3 Image sensor connector (J2) and onboard camera module (M1)
The camera add-on board uses a 5-MP MIPI camera module, e-CAM52A_MI5640_MOD from E-Con Systems that
features Omnivison OV5640 CMOS image sensor. This MIPI CSI camera module streams VGA @ 60 fps, HD (720p)
@ 60 fps and full HD (1080p) @ 30 fps. It is an auto focus camera that provides output at YUV422 format. The
camera module is mounted on the image sensor connector assembly present on the add-on board.
3.3.4 Crystal (Y1)
SG-210STF 24.0000ML0 is used to provide 24-MHz clock for the camera module.
3.3.5 External camera module connector for Raspberry Pi (J3)
The camera add-on board allows you to interface external off-the-shelf Raspberry Pi MIPI camera module such
as PCAM-5C. This is a 22-pin FPC connector. You need a 22-pin to 15-pin flex cable (CAB0306) to connect the off-
the-shelf Raspberry Pi MIPI camera module with the DVK camera add-on board.
3.3.6 GPIO interface connectors (J4, J5)
The camera add-on board also has two 20-pin mating interface/GPIO connectors to interface the camera add-
on board with the FX3 baseboard.
Note: Do not connect any external voltage source to these pins as it may permanently damage the kit.
The pins are available only for probing purpose.
