Micro SD Card Socket

Micro SD Card card socket is not directly wired connected to the B2B connector pins, but through a Texas Instruments TXS02612 SDIO port expander, which is needed Port Expander 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 card has 3.3 V signalling, but the MIO Bank 501 on the Xilinx Zynq 7000 chip is set to 1.8 V3V signal voltage level while Xilinx Zynq MIO bank uses 1.8V for VCCIO.

Dual channel USB UART/FIFO

TE0703 has on-board USB 2.0 High Speed dual high-speed USB-to-multipurpose UART/FIFO FT2232HQ controller from FTDI. Channel A can only be used in simple UART mode, Channel channel B can be used as in UART, FIFO, JTAG (MPSSE) or High Speed Serial 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 -byte serial EEPROM is available for storing custom configuration settings of the FT2232H chip. Contents of this EEPROM can be programmed with the FTDI provided software tools which can be downloaded from FTDI website. See FTDI website for more information.

Ethernet

On-board ethernet Ethernet jack J14 pins are routed to B2B connector JB1. Ethernet jack J14 LED's are all routed to CPLD Bank 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 (actual USB transceiver present on the SoM 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 Minimini-USB JTAG Interface interface (FTDI FT2232H) and controlled by DIP switch S2-3. JTAG pins are routed signals from System Controller CPLD to the JB2 connector are routed as follows:

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

...

LEDs

There are four LED's 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.

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

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

Used as CARD Detect - as the SD card connector has no CD pin

...

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