Block Diagram

<!--
Rules for all diagrams:
1. All diagrams are wrapped in the "Scroll Title" macro.
	- The title has to be named with the diagrams name
	- The anchor has the designation figure_x, whereby x is the number of the diagram

2. The Draw.IO diagram has to be inserted in the "Scroll Ignore" macro
	- Border has to be switched off in the macro edit
	- Toolbar has to be hidden in the macro edit

3. A PNG Export of the diagram has to be inserted in the "Scroll Only" macro, see Wiki page "Diagram Drawing Guidelines" how to do this step.

The workaround with the additional PNG of the diagram is necessary until the bug of the Scroll PDF Exporter, which cuts diagram to two pages, is fixed.



IMPORTANT NOTE: In case of copy and paste the TRM skeleton to a new Wiki page, delete the Draw.IO diagrams and the PNGs, otherwise due to the linkage of the copied diagrams every change in the TRM Skeleton will effect also in the created TRM and vice versa!

See page "Diagram Drawing Guidelines" how to clone an existing diagram as suitable template for the new diagram!

The boot device is selected by the mode jumpers on pin header J6. Placing a jumper at pin 13-14 sets Mode0 to low level. Mode1 is set to low level by jumper on pin 15-16. Boot modes are further described at the corresponding section of the modules, e.g. Table 2, Boot mode selection of TE0724 TRM. Default with no jumpers is boot from SD-Card.

Table 3: General overview of PL I/O signals and SoM's interfaces connected to the B2B connectors.

The TEB0724 carrier board supplies the attached module with 5V DC. All power rails on the  module and the baseboard are generated from this at the module and routed back the carrier. For detailed information about the pin out, please refer to the Pin-out Tables. 

<!--
TO-DO (future):
If Vivado board part files are available for this module, the standard configuration of the MIO pins by using this board part files should be mentioned here. This standard configuration of those pins are also apparent of the on-board peripherals of base-boards related to the module.
  -->

JTAG Interface

There is no device with JTAG port on the baseboard. JTAG access to the module is provided through B2B connector J1. This is routed to the carriers USB to JTAG/UART bridge.

Pmods

The GPIOs of the 10 Pmods (J10 to J17, J20, J21) are connected with 100 Ohm differential routing to the B2B connector. J21 is a pure I²C compatible Pmod, without additional signals. The other 9 are GPIO Pmods where despite J20 all others can be used as dual Pmods. By default VCCIO_35 is connected with a 0 Ohm resistor to 3.3V. De-soldering this resistor and using not fitted pin header J19 instead, the variable bank power VCCIO_35 for the Pmods J10, J11, J12, J13, J14, J16 can be selected.

...

Table 9: Pmod connections.

USB to JTAG/UART bridge

The TEB0724 carrier board has on-board microUSB 2.0 (J4) high-speed to UART/FIFO IC FT2232H (U1) from FTDI. Channel A can be used as JTAG Interface (MPSSE) to program on module JTAG devices. Channel B can be used as UART Interface routed to via a level shifter to the 1.8V section of the B2B connector, usually connected to the PS of the SoM. There is also a 256-byte serial EEPROM connected to the FT2232H chip pre-programmed with license code to support Xilinx programming tools.

CAN Screw Terminal

The CAN bus is routed to screw terminal J2.

...

Signals, Interfaces and Pins

Board to Board (B2B) I/Os

I/O signals connected to the B2B connector: 

microUSB JTAG/UART Interface

The microUSB connector provides JTAG access to the module through the carriers USB to JTAG/UART bridge, routed to B2B connector J1. The UART is routed via a levelshifter. There is no device with JTAG port on the baseboard.

SD Card Interface

Via dip switches S6-1 to S6-3 the variable bank power B_VCCIO_35 for the Pmods J10, J11, J12, J13, J14, J16 can be selected. Respect power regulator limits!

CAN Screw Terminal

The CAN bus is routed to screw terminal J2.

Jumpers on J22-1 to J22-3 and J22-2 to J22-4 connect proper split termination resistors to the CAN bus.

Pin Header

Pin Header J6 provides access to power functions, bootmode selection and PMIC In-Circuit Programming (For initial PMIC In-Circuit Programming of the module, Diode D28 has to be removed).

Alternatively to selecting B_VCCIO_35 by using S6 dip switches, VCCIO_35 ( e.g. SoM TE0724, Bank 35) can be selected by removing R45 and adding a jumper on optional J19. In table 18 valid jumper positions are given. Voltages and maximum current ratings could be found in the corresponding TRM of the attached module, (e.g. TE0724 TRM#PowerRails ).

Power Consumption

The maximum power consumption depends on the attached module the design running on the module and additional peripherals.

Xilinx provide a power estimator excel sheets to calculate power consumption for FPGAs. It's also possible to evaluate the power consumption of the developed design with Vivado. See also Trenz Electronic Wiki FAQ.

 * TBD - To Be Determined soon with reference design setup.

Power supply with minimum current capability of 3A for system startup is recommended.
