On-board Peripherals
32 MByte Quad SPI Flash Memory
On-board QSPI flash memory S25FL256S (U7) is used to store initial FPGA configuration. 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 used.
SPI Flash QE (Quad Enable) bit must be set to high or FPGA is unable to load its configuration from flash during power-on. By default this bit is set to high at the manufacturing plant.
eMMC Flash Memory
eMMC NAND Flash (U15) is connected to the Zynq PS MIO bank 501 pins MIO46..MIO51 (see also Variants Currently in Production for options).
Gigabit Ethernet
On-board Gigabit Ethernet PHY is provided with Marvell Alaska 88E1512 IC (U8). The Ethernet PHY RGMII interface is connected to the Zynq Ethernet0 PS GEM0. I/O voltage is fixed at 1.8V for HSTL signalling. The reference clock input of the PHY is supplied from an on-board 25.000000 MHz oscillator (U9), the 125MHz output clock signal CLK_125MHZ is connected to the pin G13 of the System Controller CPLD chip (U19).

High-speed USB ULPI PHY
Hi-speed USB ULPI PHY is provided by USB3320 from Microchip. The ULPI interface is connected to the Zynq PS USB0 via MIO28..39, bank 501. The I/O voltage is fixed at 1.8V and PHY reference clock input is supplied from the on-board 52.000000 MHz oscillator (U14).
RTC - Real Time Clock
Temperature compensated Intersil ISL12020M IC is used for Real Time Clock (U20). Battery voltage must be supplied to the module VBAT_IN pin from the carrier board to use battery backed functionality. Battery backed registers can be accessed over I2C bus at slave address of 0x6F. General purpose RAM is at I2C slave address 0x57. RTC IC is supported by Linux so it can be used as hwclock device.
MAC-Address EEPROM
A Microchip 2Kbit 11AA02E48 serial EEPROM (U17) is connected to the System Controller CPLD and contains globally unique 48-bit node address which is compatible with EUI-48TM specification. Upper 1/4 of the memory array contains 48-bit node address and is write protected.

Power and Power-On Sequence
Power Supply
Power supply with minimum current capability of 3A for system startup is recommended.
Power Consumption
Power Input Pin | Typical Current |
---|---|
VIN | TBD* |
3.3VIN | TBD* |
* TBD - To Be Determined soon with reference design setup.
Power Distribution Diagram
Current rating of Samtec Razor Beam™ LSHM B2B connectors is 2.0A per pin (2 adjacent pins powered).
Power-On Sequence
For highest efficiency of the on-board DC-DC regulators, it is recommended to use same 3.3V power source for both VIN and 3.3VIN power rails. Although VIN and 3.3VIN can be powered up in any order, it is recommended to power them up simultaneously.
It is important that all carrier board I/Os are 3-stated at power-on until System Controller CPLD sets PGOOD signal high (B2B connector JM1, pin 30), or 3.3V is present on B2B connector JM2 pins 10 and 12, meaning that all on-module voltages have become stable and module is properly powered up.
See also Xilinx datasheet DS187 for additional information. User should also check related carrier board documentation when choosing carrier board design for TE0720 module.
NOSEQ input signal
NOSEQ input signal from the carrier board can be used to control output of the two DC-DC converters U1 and U3. It works in conjunction with the System Controller CPLD firmware controlled ON_1V0 and ON_1V8 input signals of the U21 and U25 gate ICs.
If NOSEQ input signal from the carrier board is low (logical 0), signals ON_1V0 and ON_1V8 can be driven by System Controller CPLD to control outputs of the U1 and U3 DC-DC converters. | If NOSEQ input signal from the carrier board is high (logical 1), state of the ON_1V0 and ON_1V8 signals is irrelevant and DC-DC converters U1 and U3 outputs are always enabled. |
Initial state of the ON_1V0 and ON_1V8 signals and therefore also functionality of the NOSEQ signal depend on the System Controller CPLD firmware.
