Overview

Refer to https://shop.trenz-electronic.de/de/Download/?path=Trenz_Electronic/carrier_boards/TE0703 for downloadable version of this manual and the rest of available documentation.

The Trenz Electronic TE0703 Carrier Board is a base-board for 4x5 SoM'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 SoM's.

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

Initial Delivery State

Board is shipped in following configuration:

• VCCIO voltage selection jumpers are all set to 1.8 V.
• S1 switch configured as reset button in CPLD.
• Two VG96 backplane connectors are not soldered to the board, but they are included in the package as separate components.
• S2 DIP switches are configured as follows:

Different delivery configurations are available upon request.

Signals, Interfaces and Pins

Board to Board (B2B) I/O's

For detailed information about the B2B pin out, please refer to the Master 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.

Dual channel USB UART/FIFO

TE0703 has on-board USB 2.0 High Speed UART/FIFO FT2232HQ from FTDI. Channel A can only be used in simple UART mode, Channel B can be used as UART, FIFO, JTAG (MPSSE) or High Speed Serial modes. An standard 256 Byte EEPROM to store custom Configuration settings for FT2232H is available. EEPROM settings can be changed using FTDI provided tools that can be downloaded from FTDI website. See FTDI website for more information.

Ethernet 

On-board ethernet jack J14 pins are routed to B2B connector JB1. Ethernet jack J14 LED's are all routed to CPLD Bank 1.

USB Interface

TE0703 board has two physical USB sockets:

• J4 as mini USB type B socket wired to the on-board FTDI FT2232H chip.
• J6 as USB type A wired to B2B connector 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 on-board:

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

DIP switches

Power and Power-On Sequence

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 power consumption for TE0703-05 + TE0715-01 module with SD micro card inserted, ethernet connected, link up, system booted into Linux prompt and idling 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 voltages options.
