Overview
The Trenz Electronic TE0782 is a high-performance, industrial-grade SoM (System on Module) with industrial temperature range based on Xilinx Zynq-7000 SoC (XC7Z035, XC7Z045 or XC7Z100).
These highly integrated modules with an economical price-performance-ratio have a form-factor of 8,5 x 8,5 cm and are available in several versions.
All parts cover at least industrial temperature range of -40°C to +85°C. The module operating temperature range depends on customer design and cooling solution. Please contact us for options and for modified PCB-equipping due increasing cost-performance-ratio and prices for large-scale order.

Rules for all diagrams:
1. All diagrams are wrapped in the "Scroll Title" macro.
- The title has to be named with the diagrams name
- The anchor has the designation figure_x, whereby x is the number of the diagram
2. The Draw.IO diagram has to be inserted in the "Scroll Ignore" macro
- Border has to be switched off in the macro edit
- Toolbar has to be hidden in the macro edit
3. A PNG Export of the diagram has to be inserted in the "Scroll Only" macro
The workaround with the additional PNG of the diagram is necessary until the bug of the Scroll PDF Exporter, which cuts diagram to two pages, is fixed.
IMPORTANT NOTE: In case of copy and paste the TRM skeleton to a new Wiki page, delete the Draw.IO diagrams and the PNGs, otherwise due to the linkage of the copied diagrams every change in the TRM Skeleton will effect also in the created TRM and vice versa!
See page "Diagram Drawing Guidelines" how to clone an existing diagram as suitable template for the new diagram!

Boot Process
4 of the 7 boot mode strapping pins (MIO2 ... MIO8) of the Xilinx Zynq-7000 SoC device are hardware programmed on the board, 3 of them are set by the SC CPLD firmware. The boot strapping pins are evaluated by the Zynq device soon after the 'PS_POR' signal is deasserted to begin the boot process (see section "Boot Mode Pin Settings" of Xilinx manual UG585).
The TE0782 board is programmed in the SC CPLD firmware to boot initially from the on-board QSPI Flash memory U38. See section Bootmode in the TE0782 SC CPLD reference Wiki page.
The JTAG interface of the module is provided for storing the data to the QSPI Flash memory through the Zynq-7000 device.

Table 3: MGT lanes
There are 2 clock sources for the GTX transceivers. MGT_CLK1 and MGT_CLK4 are connected directly to B2B connector J3 and J1, so the clock can be provided by the carrier board. Clocks MGT_CLK0, MGT_CLK3, MGT_CLK5 and MGT_CLK6 are provided by the on-board clock generator (U2). As there are no capacitive coupling of the data and clock lines that are connected to the connectors, these may be required on the user’s PCB depending on the application.

Pin Definitions
Pins with names ending with _VRN and _VRP are connected to Zynq PL HP bank special purpose pins VRN/VRP and can be routed to DCI calibration resistors on the baseboard. Otherwise they are usable as general purpose I/Os.
Bank 35 has 100 ohm DCI calibration resistors installed, it is also possible to "borrow" the DCI calibration from bank 35 for banks 34 and 33. For more detailed information about the DCI check Xilinx documentation.
On-board Peripherals
System Controller CPLD
The System Controller CPLD (U14) is provided by Lattice Semiconductor LCMXO2-1200HC (MachXO2 product family). It is the central system management unit with module specific firmware installed to monitor and control various signals of the FPGA, on-board peripherals, I/O interfaces and module as a whole.
See also TE0782 CPLD reference Wiki page.
eMMC Flash Memory
eMMC Flash memory device (U15) is connected to the Zynq PS MIO bank 500 pins MIO10..MIO15. eMMC chips MTFC4GMVEA-4M IT (Flash NAND-IC 2x 16 Gbit) is used with 4 GByte of memory density.
DDR3L Memory
By default TE0782-02 module has two 16-bit wide IM (Intelligent Memory) IM4G16D3FABG-125I DDR3L SDRAM (DDR3-1600 Speedgrade) chips (U10, U19) arranged into 32-bit wide memory bus providing total of 1 GBytes of on-board RAM.
Quad SPI Flash Memory
Two quad SPI compatible serial bus flash memory for FPGA configuration file storage is provided by Spansion S25FL256SAGBHI20 (U38) with 256 Mbit (32 MByte) memory density. 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 to be used. The maximum data transfer rate depends on the bus width and clock frequency.
Gigabit Ethernet PHYs
On-board Gigabit Ethernet PHYs (U18, U20) are provided by Marvell Alaska 88E1512. The Ethernet PHYs' RGMII interfaces are connected to the Zynq's PS MIO bank 501 and to PL bank 9. I/O voltage is fixed at 1.8V for HSTL signaling. The reference clock input of both PHYs is supplied from an on-board 25.000000 MHz oscillator (U11).
High-speed USB ULPI PHYs
Hi-speed USB ULPI PHYs (U4. U8) are provided with USB3320 from Microchip. The ULPI interfaces are connected to the Zynq PS USB0 and USB1 via MIO28..51, bank 501 (see also section USB interface). The I/O voltage is fixed at 1.8V and PHY reference clock input is supplied from the on-board 52.000000 MHz oscillator (U7).
MAC Address EEPROMs
Two Microchip 24AA025E48 serial EEPROMs (U22, U24) contain globally unique 48-bit node address, which are compatible with EUI-48(TM) specification. The devices are organized as two blocks of 128 x 8 Kbit memory. One of the blocks stores the 48-bit node address and is write protected, the other block is available for application use. The MAC address EEPROMS areaccessible over I2C bus (see also section I²C interface).
Configuration EEPROM
The TE0782 board contains one EEPROM (U26) for configuration and general user purposes. The EEPROMs is provided by Microchip 24LC128-I/ST with 128 KBit memory density, the EEPROM is areaccessible over I2C bus (see also section I²C interface).
Programmable Clock Generator
There is a Silicon Labs I2C programmable clock generator Si5338A (U2) chip on-board. It's output frequencies can be programmed using the I2C bus address 0x70 or 0x71. Default address is 0x70, IN4/I2C_LSB pin must be set to high for address 0x71.
A 25.000000 MHz oscillator (U3) is connected to the pin IN3 and is used to generate the output clocks. The output voltage of the oscillator is provided by the 1.8V power rail, thus making output frequency available as soon as 1.8V is present. All 4 of the Si5338 clock outputs are connected to the MGT banks of the Zynq device. It is possible to use the clocks connected to the GTR bank in the user's logic design. This is achieved by instantiating a IBUFDSGTE buffer in the design.
Once running, the frequency and other parameters can be changed by programming the device using the I2C bus connected between the FPGA (master) and clock generator (slave). For this, proper I2C bus logic has to be implemented in FPGA.

To avoid any damage to the module, check for stabilized on-board voltages should be carried out (i.e. power good and enable signals) before powering up any Zynq's I/O bank voltages VCCO_x. All I/Os should be tri-stated during power-on sequence. |
Power Distribution Dependencies
The Trenz TE0782 SoM is equipped with two quad DC-DC voltage regulators to generate required on-board voltage levels 1V, 3.3V, 1.8V, 1.2V_MGT, 1V_MGT. Additional voltage regulators are used to generate voltages 1.5V, VTT, VTTREF and 1.8V_MGT.
The power supply voltage 'C3.3V' of System Controller CPLD of the SoM have to be externally supplied with 3.3V nominal.
There are following dependencies how the initial voltages of the power rails on the B2B connectors are distributed to the on-board DC-DC converters, which power up further DC-DC converters and the particular on-board voltages:
