Overview

The Trenz Electronic TE0703 Carrier Board is a base-board for 4 x 5 SoMs, 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 4 x 5 SoMs.

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

Refer to http://trenz.org/te0703-info for the current online version of this manual and other available documentation.

• VCCIO voltage selection jumpers are all set to 1.8 V.
• SD IO Voltage jumper J11 is set to 1.8V.
• 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.

Configuration Signals

The configuration signals are managed by the CPLD and therefore Firmware dependet. Standart configuration is given below.

Signals, Interfaces and Pins

Board to Board (B2B) I/Os

I/O signals connected to the B2B connector: 

Micro SD Card Socket

Micro SD card socket is connected to the B2B connector through a Texas Instruments TXS02612 SDIO port expander for voltage translation. The Micro SD card has 3.3V signal voltage level while most 4 x 5 modules use 1.8V for the SD card interface.

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 (USB transceiver used depends on the SoM model used). Instead of J6, a micro USB connector J12 can be assembled

Ethernet 

On-board Ethernet jack J14 pins are routed to B2B connector JB1. Ethernet jack J14 LED signals PHY_LED1, PHY_LED2, PHYLED1R and PHYLED2R are all routed to System Controller CPLD bank 1.

Ethernet PHY connection

External VG96 Connector I/Os

I/O signals connected to the B2B connector: 

On-board Peripherals

USB to JTAG and UART bridge

TE0703 has on-board USB JTAG and UART solution based on UART/FIFO controller from FTDI (U4). FTDI EEPROM is pre-programmed with license code to support Xilinx programming tools.

JTAG and UART signals along with some more FTDI IOs are routed to the CPLD. See CPLD Firmware TE0703 CPLD - CC703S#CC703S for further description.

CPLD

TE0703-06 has a Lattice LCMXO2-1200HC as a system controller. for further function description see Firmware TE0703 CPLD - CC703S#CC703S,

SD IO Levelshifter

SD IO levelshifter (U2) is used in congntion with jumper J11 to select the correct SD IO interface voltage of the SoM. 

I²C Repeater

For power sequence reasons the I²C bus is routed via a repater (U7) to to ensure no IOs of the SoM are driven before M3.3VOUT is up.

LEDs

There are four on-board LEDs. D3 and D4 are  connected to the B2B connector JB2 pins FLED1 and FLED2 respectively and can be read by CPLD firmware. See TE0703 CPLD - CC703S#CC703S-LED.

DIP switches

DIP switch settings are CPLD Firmware dependent, default firmware:

Mode status is displayed on TE0703 LEDs, see TE0703 CPLD - CC703S#CC703S-LED.

Jumper

TE0703-06 has 5 Voltage selection jumpers. Select 1.8V or 3.3V in accordenc of the attached module capabilities and your needs. Refer to the 4 x 5 Module Integration Guide for VCCIO voltages options.

Power

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

Power Supply

Single power supply with minimum current capability of 3A at 5V for system startup is recommended.

Power Consumption

Typical power consumption for TE0703-05 + TE0715-01 module with SD micro card inserted, Ethernet connected and 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.
