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.

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 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 4x5 modules use 1.8V for the SD card interface.

USB JTAG and UART

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

Do not access the FT2232H EEPROM using FTDI programming tools, doing so will erase normally invisible user EEPROM content and invalidate stored Xilinx JTAG license. Without this license the on-board JTAG will not be accessible any more with any Xilinx tools. Software tools from FTDI website do not warn or ask for confirmation before erasing user EEPROM content.

Ethernet

On-board Ethernet jack J14 pins are routed to B2B connector JB1. Ethernet jack J14 LEDs PHY_LED1 and PHY_LED2 are both routed to System Controller 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 (USB transceiver used depends on the SoM model used).

JTAG Interface

JTAG access to the System Controller 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 signals from System Controller CPLD to the JB2 connector are routed as follows:

JTAG Signal	B2B Connector Pin
TCK	JB2-100
TDO	JB2-98
TDI	JB2-96
TMS	JB2-94

LEDs

There are four on-board LEDs:

LED	Color	Description
D1	Red	FTDI UART receive activity.
D2	Green	FTDI UART transmit activity.
D3	Red	CPLD signal FL_0.
D4	Green	CPLD signal FL_1.

LEDs D3 and D4 are also connected to the B2B connector JB2 pins FLED1 and FLED2 respectively and can be controlled by SoM FPGA firmware.

DIP switches

Switch	ON	OFF
S2-1	User configurable, routed to CPLD	User configurable, routed to CPLD
S2-2	User configurable, routed to CPLD	User configurable, routed to CPLD
S2-3	JTAG enabled for B2B connector JB2	JTAG enabled for CPLD
S2-4	Boot from SD Card	Boot from QSPI flash on module

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

Power Input Pin	Max Current
VIN (power connector jack J13)	4A

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 altogether, see next chapter.

VCCIO voltage selection jumpers J5, J8, J9 and J10

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

Jumper J5	1-2	2-3	Voltage
VCCIOA	ON	OFF	1.8 V
VCCIOA	OFF	ON	3.3 V

Jumper J8	1-2	2-3	Voltage
VCCIOB	ON	OFF	1.8 V
VCCIOB	OFF	ON	3.3 V

Jumper J9	1-2	2-3	Voltage
VCCIOC	ON	OFF	1.8 V
VCCIOC	OFF	ON	3.3 V

Jumper J10	1-2	2-3	Voltage
VCCIOD	ON	OFF	1.8 V
VCCIOD	OFF	ON	3.3 V

Take care of the VCCO voltage ranges of the particular PL IO-banks (HR, HP) of the mounted SoM, otherwise damages may occur to the FPGA. Therefore, refer to the TRM of the mounted SoM to get the specific information of the voltage ranges.

It is recommended to set and measure the PL IO-bank supply-voltages before mounting of TE 4 x 5 module to avoid failures and damages to the functionality of the mounted SoM.
