QSPI Interface

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 TE0722 FPGA 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 Table 2: Selecting power-on boot device.

On-board Peripherals

Quad SPI Flash Memory

On-board QSPI flash memory (U5) is provided by Cypress Semiconductor Serial Flash Memory S25FL127SABMFV101 with 128 MBit (16 MByte) storage capacity. This non volatile memory is used to store initial configuration data. Besides initial configuration data, remaining free flash memory can be used for user application and data storage.

Proximity and Ambient Light Sensor

The TE0722-02 Zynq SoC board is equipped with the Si1143 infrared proximity and ambient light sensor. On-board three red LEDs D1, D3 and D5 are connected to the light sensor to use the proximity sensing functionality. For more details and how to configure and use this chip, refer to the Si1141/42/43 data sheet.

Oscillator

The Zynq SoC board one reference clocking signal as system clock provided by on-board oscillator U8:

Table 9: Clock sources overview

On-board LEDs

There are 6 LEDs fitted on the Zynq SoC board. The LEDs are user configurable to indicate for example any system status.

Connectors

All connectors are for 100mil (2.54mm pitch) headers, all connector locations are in 100mil grid. The module's PCB provides footprints to mount and solder optional pin headers, if those are not factory-fitted on module.

Power and Power-On Sequence

To power-up a module, power supply with minimum current capability of 1A is recommended.

Power Supply

TE0722-02 needs one single power supply with nominal of 3.3V at all variants. Following diagram shows the dependencies of the power supply:

Power Consumption

Table 11: Module power consumption

*TBD - To Be Determined.

The maximum power consumption of the module mainly depends on the design running on the Zynq SoC's FPGA and ambient temperature.

Xilinx provide a power estimator excel sheets to calculate power consumption. It is also possible to evaluate the power consumption of the developed design with Vivado. See also Trenz Electronic Wiki FAQ.

Power

...

-On Sequence

There is no specific or special power-on sequence, single power source is needed as 3.3V as power supply voltage.

Voltage Monitor Circuit

The voltages 1.0V (core voltage) and 3.3V are monitored by the voltage monitor circuit U6, which generates the POR_B reset signal at power-on. A manual reset is also possible by driving the connector pin P1-10 ('NRST') to GND. Leave this pin unconnected or connect to VDD (3.3V) when unused.
