Initial Delivery State

Table 1: Initial delivery state of programmable devices on the module.

Boot Process

Boot mode is selected via two Mode pins at B2B connector J2. By default the TE0724 supports JTAG and SPI Boot Mode. Connecting a SD Card via B2B connector to MIO Pins (See SD Card Interface) gives the possibility to boot from SD Card. The Mode pins are pulled up at the module.

Table 2: Boot mode selection.

Signals, Interfaces and Pins

<!--
Connections and Interfaces or B2B Pin's which are accessible by User
  -->

Board to Board (B2B) I/Os

I/O signals connected to the SoCs I/O bank and B2B connector: 

Table 3: General overview of PL I/O signals connected to the B2B connectors.

All PS MIO banks as well as PL bank 34 are powered by on-module DC-DC power rails. Valid VCCO_35 for PL bank 35 should be supplied via the B2B connector.

For detailed information about the pin out, please refer to the Pin-out Tables. 

The configuration of the PS I/Os MIO40 to MIO51 depend on the carrier board peripherals connected to these pins.

<!--
TO-DO (future):
If Vivado board part files are available for this module, the standard configuration of the MIO pins by using this board part files should be mentioned here. This standard configuration of those pins are also apparent of the on-board peripherals of base-boards related to the module.
  -->

<!--
MGT lanes should be listed separately, as they are more specific than just general I/Os.  
  -->

JTAG Interface

JTAG access to the ZYNQ SoC is provided through B2B connector J1 and testpoints.

Table 4: JTAG interface signals.

System Controller Pins

Special purpose pins are available for System Controller functions and are routed to the Power Management IC (U4) with the following default configuration:

Table 5: System Controller CPLD I/O pins.

<!--
For the detailed function of the pins and signals, the internal signal assignment and implemented logic, look to the Wiki reference page SC CPLD of this module or into the bitstream file of the SC CPLD.
Add link to the Wiki reference page of the SC CPLD, if available.
   -->

Quad SPI Interface

Quad SPI Flash (U13) is connected to the Zynq PS QSPI_0 interface via PS MIO bank 500, pins MIO1 ... MIO6.

Table 6: Quad SPI interface signals and connections.

SD Card Interface

There is no physical SD Card slot on the module. Three different interface options are possible at a carrier via the PS MIO 10 to 15 or 40 to 45 or 46 to 51 plus additional MIOs for SD Card Detect and Write Protect as well as SD Card Power Controls. For details compare Xilinx UG585-Zynq-7000-TRM Table 2-4.

Ethernet Interface PHY

The TE0724 is equipped with a Marvell Alaska 88E1512 Gigabit Ethernet PHY (U7) connected to PS Ethernet GEM0. The I/O Voltage is fixed at 1.8V for HSTL signaling. 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 PL IO_L11P_T1_SRCC_34.

Table 7: Ethernet PHY connections.

CAN PHY

A felxible data rate CAN Transceiver is provided by a Microchip MCP2542FDT.

DDR Memory

By default TE0724 module has 2 DDR3L SDRAM chips arranged into 32-bit wide memory bus providing total of 1 GBytes of on-board RAM. Different memory sizes are available optionally.

Quad SPI Flash Memory

On-board QSPI flash memory (U13) on the TE0724-04 is a ISSI IS25LP512M with 512 Mbit (64 MByte) storage capacity. This non volatile memory 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.

MAC Address EEPROM

A Microchip 24AA025E48 serial EEPROM (U23) contains a globally unique 48-bit node address, which is compatible with EUI-48(TM) specification. The device is organized as two blocks of 128 x 8-bit memory. One of the blocks stores the 48-bit node address and is write protected, the other block is available for application use. It is accessible over I²C bus with slave device address 0x53.

USER EEPROM

A Microchip 24AA128T serial EEPROM (U10) is available for e.g. module identification and user Data. The device has 128Kbit memory with max 64 bytes page write capability. It is accessible over I²C bus with slave device address 0x50.

Oscillators

The module has following reference clock signals provided by on-board oscillators and external source from carrier board:

Power and Power-On Sequence

<!--
If power sequencing and distribution is not so much, you can join both sub sections together

Power Consumption

The maximum power consumption of a module mainly depends on the design running on the FPGA.

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

Table 13: Typical power consumption.

 * TBD - To Be Determined soon with reference design setup.

Power supply with minimum current capability of ...A for system startup is recommended.

The on-board voltages of the TE0724 SoC module will be powered-up in order of a determined sequence after the external voltages VIN  is available and nONKEY is asserted.

Power Distribution Dependencies

DCDC U8 component is either TPS82140 (2 A) or MUN12A (3 A) depending on the variant.

See Xilinx data sheet for additional information. User should also check related base board documentation when intending base board design for TE0724 module.

Power-On Sequence

The TE0724 SoM meets the recommended criteria to power up the Xilinx Zynq MPSoC properly by keeping a specific sequence of enabling the on-board DC-DC converters dedicated to the particular functional units of the Zynq chip and powering up the on-board voltages. For a detailed description of the configurable Power Management IC please refer to the datasheet of dialog semicondutor DA9062.

Following diagram clarifies the sequence of enabling the particular on-board voltages, which will power-up in ascending order as listed in the blocks of the diagram:

Power Rails

Current rating of theSamtec connector is 1.6A per pin (1 pin powered per row).
