Boot Process

The 7 boot mode strapping pins on the TE0723 module are set to boot the system from quad SPI Flash only. For additional information refer to the TE0723 schematic and Xilinx UG585 Zynq-7000 All Programmable SoC Technical Reference Manual section "Boot Mode Pin Settings".

Signals, Interfaces and Pins

I/O Signals

List of I/O signals between PS/PL banks and external connectors:

Table x: .

JTAG Interface

JTAG access to the Xilinx Zynq XC7Z010 SoC is provided through FTDI USB/UART FIFO bridge connected to the J9 Micro USB connector.

Quad SPI Interface

Following line is just an example, change it to your needs.

Quad SPI Flash (U14) is connected to the Zynq PS QSPI0 interface via PS MIO bank 500, pins MIO1 ... MIO6.

Note that table column says "Signal Name", it should match the name used on the schematic.

Table x: Quad SPI interface signals and connections.

SD Card Interface

TE0723 module has on-board SD Card socket (J10) with card detect switch wired to the SoC PS MIO bank 500.

USB Interface

ESP Wi-Fi Interface

Interface for the ESP8266 Wi-Fi module is provided through connector J5.

I2C Interface

I²C interface pins from the Zynq SoC PL bank 34 are connected to the connector J1. There are no on-board I2C slave devices.

Table x: .

On-board Peripherals

DDR Memory

TE0723 module has up to 512-MBytes of DDR3L SDRAM arranged into 32-bit wide memory bus providing total of 1 GBytes of on-board RAM. Different memory sizes are available optionally.

Quad SPI Flash Memory

On-board quad SPI Flash memory S25FL127S (U5) is used to store initial FPGA configuration. Besides FPGA configuration, remaining free flash memory can be used for user application storage. All four SPI data lines are connected to the Zynq SoC's PS, allowing x1, x2 or x4 data bus widths. Maximum data rate depends on the bus width and clock frequency used.

Dual High-speed USB to Multipurpose UART/FIFO

FT2232H...

High-speed USB ULPI PHY

Hi-speed USB ULPI PHY (U18) is provided with USB3320 from Microchip. The ULPI interface is connected to the Zynq SoC's PS USB0 via MIO28..39, bank 501 (see also section). The I/O voltage is fixed at 3.3V and PHY reference clock input is supplied from the on-board 52.000000 MHz oscillator (U14).
