Initial Delivery State

Configuration Signals

Boot process.

The TE0716 supports QSPI and SD Card boot modes, which is controlled by the insertion of the SD card before powering on.

Reset process.

The nRST signal active low reset input, forces PS_POR_B to apply a master reset of the entire Zynq. This reset could be manually done by pressing a switch. This signal could be also reached by a B2B large connector.

This nRST signal (active low) is also held until all FPGA power supplies set their Power Good signals.

Furthermore, if the FPGA core voltage drops under 0.84V or the 3.3V power supply drops to 2.94V or less, this nRST signal is also activated by the Voltage Monitor.

See more about the Power-on Reset (PS_POR_B) signal in the “Zynq-7000 SoC Technical Reference Manual” (“UG585”).

On-board Peripherals

Quad SPI Flash Memory

On-board 32MByte QSPI flash memory S25FL256S (U7) could be used to store the initial FPGA configuration file. After configuration completes, the remaining free memory can be used for application 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 used.

• Part number: S25FL256SAGBHI20
• Supply voltage: 3.3V (2.7V - 3.6V).
• Speed: 133MHz max.
• Temperature: Industrial Range -40°C to +85°C.

ADCs

The TE0716 module has 10x 12-Bit Low Power SAR Analog-to-Digital Converter, fully differential input, signed output, with SPI−compatible interface (NCD98011), which are connected to the FPGA PL BANK34.

• Part number: NCD98011XMXTAG
• Analog supply and ADC reference voltage: 3.3V (1.65V – 3.6V).

MAC-Address EEPROM

A 2Kbit 24AA025E48 serial EEPROM I2C memory (U24), connected to the BANK501 PSMIOs, contains a globally unique 48-bit node address, which is compatible with EUI-48TM specification. The device is organized as two blocks of 128 x 8-bit memory. One of the blocks, the upper half of the array (80h-FFh), stores the 48-bit node address and is permanently write-protected, while the other block is available for application use.

• Part number: 24AA025E48T-I/OT
