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:
| Clock Source | Frequency | Clock Input Destination |
|---|---|---|
| SiTime SiT8008AI Oscillator, U8 | 33.333333 MHz | Zynq PS Bank 500, pin C7 |
Table 10: 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.
| LED | Color | Connected to | Signal Schematic Name | Description and Notes |
|---|---|---|---|---|
| D1 | Red | Light sensor U4, pin 6 | - | Proximity sensing functionality of light sensor U4 |

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:
Figure 4: Module power supply dependencies
Power Consumption
| Board Variant | FPGA | Design | Typical Power, 25°C ambient |
|---|---|---|---|
| TE0722-02I | XC7Z010-1CLG225I | Not configured | TBD* |
| TE0722-02 | XC7Z010-1CLG225C | Not configured | TBD* |
| TE0722-02-07S-1C | XC7Z007S-1CLG225C | Not configured | TBD* |
Table 12: 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.
