The Trenz Electronic TE0703 Carrier Board is a base-board for 4x5 SoMsSoM's, which exposes the MIO- and the PS/PL-pins of the SoM to accessible connectors and provides a whole range of on-board-components to test and evaluate Trenz Electronic 4x5 SoMsSoM's.

See page "4 x 5 cm carriers" to get information about the SoMs SoM's supported by the TE0703 Carrier Board.

Signals, Interfaces and Pins

Board to Board (B2B) I/O's

For detailed information about the B2B pin out, please refer to the Master Pinout Pin-out Table. 

Micro SD Card Socket

Micro SD Card socket is not directly wired to the B2B connector pins, but through a Texas Instruments TXS02612 SDIO port expander, which is needed for voltage translation due to the different voltage levels of the Micro SD Card and MIO bank 501 of the Xilinx Zynq 7000 chip. The Micro SD Card has 3.3 V signalling, but the MIO Bank 501 on the Xilinx Zynq 7000 chip is set to 1.8 V. !!! (card detect signal...)

Dual channel USB UART/FIFO

...

• J4 as mini USB type B socket wired to the on-board FTDI FT2232H chip.
• J6 as USB type A wired to B2B connector JM3 (there is usually something like SMSC USB3320 or similar USB transceiver on the module).JB3 (actual USB transceiver present on the SoM depends on the SoM model).
  

JTAG Interface

JTAG access to the CPLD and Xilinx Zynq chip on the SoM is provided via Mini-USB JTAG Interface (FTDI FT2232H) and controlled by DIP switch S2-3. JTAG pins are routed from CPLD to the JB2 connector as follows:

LED's

There are four LED's onboardon-board:

LED's D3 and D4 are also connected to the 4x5 B2B connector pins. Those LEDs JB2 pins FLED1 and FLED2 respectively and can be controlled by 4x5 SoM FPGA Modulemodule.

Power and Power-On Sequence

Power

...

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

Power Supply

TE0703 needs one single power supply with nominal of 5V.

Power Consumption

Typical value: power consumption for TE0703-05 + TE0715-01 module . with SD micro card inserted. Ethernet , ethernet connected, link up. System , system booted into Linux prompt and idling . Average power consumption was is 5V / 0.55A.

Power-On Sequence

It is not allowed to feed any voltage to any external I/O pin before there is no power indication on M3.3VOUT pins. Presence of 3.3V on B2B JB2 connector pins 9 and 11 indicates that module is properly powered up and ready.

If any of the VCCIOA, VCCIOB, VCCIOC or VCCIOD will be powered through external connectors J1 or J2, then corresponding VCCIO jumper should also be removed altogether, see next chapter.

 VCCIO voltage selection jumpers J5, J8, J9 and J10

Refer to the 4x5 Module Integration Guide for VCCIO voltage voltages options.
