Quad SPI Flash Memory
On-board QSPI flash memory is used to store initial FPGA configuration. Datasheet is provided in Texas Instruments. Besides FPGA configuration, remaining free flash memory can be used for user application and data storage. All four SPI data lines are connected to the FPGA allowing x1, x2 or x4 data bus widths. Maximum data rate depends on the selected bus width and clock frequency.
Quad SPI Flash (U7) is connected to the Zynq PS QSPI0 interface via PS MIO bank 500.

Power on Sequence
The TE07028 SoM meets the recommended criteria to power up the Xilinx Zynq properly by keeping a specific sequence of enabling the on-board DC-DC converters and regulators dedicated to the particular functional units of the Zynq chip and powering up the on-board voltages. When the U8 and U9 generates PWRGD signal, it turns on the U4 which generates PWRGD_3.3V, it turns on the U6 and it generates PWROK signal which is connected to MR. Whenever the supply voltage for U12 drops down below the threshold it resets the system. Actually it resets the system when all regulators are working.

Voltage Monitor Circuit
The microprocessor supervisory circuits monitor system voltages asserting an open-drain RESET signal when the SENSE voltage drops below a preset threshold or when the manual reset (MR) pin drops to a logic low. The RESET output remains low for the user adjustable delay time after the SENSE voltage and MR return above their thresholds. Datasheet is available in Texas Instruments website.
