Initial Delivery State

Table 1: Initial delivery state of programmable devices on the module

Boot Process

The 7 boot mode strapping pins (MIO2 ... MIO8) of the Xiliny Zynq Z-7010 device are hardware programmed on the board. They are evaluated by the Zynq device soon after the 'POR_B'.signal is deasserted to begin the boot process (see section "Boot Mode Pin Settings" of Xilinx manual UG585).

The TE0723 Zynq board is hardware programmed to boot initially from the on-board QSPI Flash memory U5. The JTAG interface of the module is provided for storing the data to the QSPI Flash memory through the Zynq device.

JTAG Interface

JTAG access to the Xilinx Zynq XC7Z010 SoC is provided through FTDI USB/UART FIFO bridge connected to the Micro USB2 connector J9.

Quad SPI Interface

Quad SPI Flash (U5) is connected to the Zynq PS QSPI0 interface via PS MIO bank 500, pins MIO1 ... MIO6.

Table 4: Quad SPI interface signals and connections

SD Card Interface

TE0723 module has on-board 3.3V SD Card socket (J10) with card detect switch wired to the SoC PS MIO bank 500.

ESP Wi-Fi Interface

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

Table 6: ESP8266 Wi-Fi module interface.

I2C Interface

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

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... U3.

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).

Microwire Serial EEPROM

There is a 2-Kbit (128 x 16-bit organization) Microwire compatible serial EEPROM 93AA56B (U6) connected to the FTDI FT2232H dual high-speed USB to multipurpose UART/FIFO (U3). This external EEPROM allows each of the FTDI FT2232H chip’s channels to be independently configured as a serial UART (RS232 mode), parallel FIFO (245) mode or fast serial (optical isolation). The external EEPROM can also be used to customize the USB VID, PID, serial number, product description strings and power descriptor value of the FT2232H for OEM applications. Other parameters controlled by the EEPROM include remote wake up, soft pull down on power-off and I/O pin drive strength.

High-Speed Analog Multiplexer

TE0723 module has a on-board TI CD74HC4051 high-speed CMOS logic analog multiplexer (U10) with 8 analog inputs from connectors J4 and J11, and single analog output connected to the operational amplifier (see next section).

Low-power Operational Amplifier

8-input analog multiplexer output is connected to the on-board Microchip Technology MCP6001 operational amplifier (U11). Amplifier output is connected to the Zynq SoC's PS bank 0, XADC dedicated differential analog input pins VP_0 and VN_0.

Oscillators

The module has following reference clock signals provided by on-board oscillators:

Table 8: Reference clock signals.

On-board LEDs

There are three LEDs on-board TE0723:

Table 9: On-board LEDs.

Power and Power-On Sequence

Power Supply

5V power can be supplied by the external power supply through connector J12 or via USB connection to the host system through USB connector J8 or J9. Minimum current capability of 1A for external power supply is recommended.

Power Consumption

Power consumption is to be determined by the user and depends on SoC's FPGA design and connected hardware.

Power-On Sequence

There is no specific power-on sequence, system will power-up automatically when 5V is present either through J8, J9 or J12.
