Overview

The Trenz Electronic TE0783 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.

Block Diagram

<!--
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!

Initial Delivery State

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

Boot Process

6 of the 7 boot mode strapping pins (MIO2 ... MIO8) of the Xilinx Zynq-7000 SoC device are hardware programmed on the board, 1 of them is 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 TE0783 boot mode is selected by the pin 'CPLD_GPIO3' of the SC CPLD, which is connected to B2B pin J2-16 to either from the on-board QSPI Flash memory U38 or SD IO interface. See section Bootmode in the TE0783 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.

Signals, Interfaces and Pins

Board to Board (B2B) I/Os

Zynq-7000 SoC's I/O banks signals connected to the B2B connectors:

Table 2: General overview of board to board I/O signals

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

MGT Lanes

The Xilinx Zynq-7000 SoC used on the TE0783 module has 16 MGT transceiver lanes. All of them are wired directly to B2B connectors J1 and J3. MGT (Multi Gigabit Transceiver) lane consists of one transmit and one receive (TX/RX) differential pairs, four signals total per one MGT lane with data transmission rates up to 12.5Gb/s per lane (Xilinx GTX transceiver). Following table lists lane number, FPGA bank number, transceiver type, signal schematic name, board-to-board pin connection and FPGA pins connection:

Table 3: MGT lanes

There are 2 clock sources for the GTX transceivers. MGT_CLK1, MGT_CLK2, MGT_CLK4 and MGT_CLK7 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.

JTAG Interface

JTAG access to the Xilinx Zynq-7000 is provided through B2B connector J3.

On-board Peripherals

System Controller CPLD

The System Controller CPLD (U32) is provided by Lattice Semiconductor LCMXO2-4000HC (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 TE0783 CPLD reference Wiki page.

eMMC Flash Memory

eMMC Flash memory device (U28) is connected to the Zynq PS MIO bank 501 pins MIO46..MIO51. eMMC chips MTFC4GMVEA-4M IT (Flash NAND-IC 2x 16 Gbit) is used with 4 GByte of memory density.

DDR3L Memory

By default TE0783-01 module has two 16-bit wide IM (Intelligent Memory) IM4G16D3FABG-125I DDR3L SDRAM (DDR3-1600 Speedgrade) connected to the PS DDR memory bank 502, the chips are arranged into 32bit wide memory bus providing total of 1 GBytes of on-board RAM.

Another 4 chips are arranged into 64bit wide memory bus prodivding total of 2 GByte on-board RAM connected to the PL HP banks 34,35,36.

Quad SPI Flash Memory

One quad SPI compatible serial bus Flash memory (U38) for FPGA configuration file storage is provided by Spansion S25FL256SAGBHI20 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 PHY

On-board Gigabit Ethernet PHY (U18) is provided by Marvell Alaska 88E1512. The Ethernet PHY's RGMII interface is connected to the Zynq's PS MIO bank 501. 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 (U11).

High-speed USB2 ULPI PHY

Hi-speed USB ULPI PHY (U4) is provided with USB3320 from Microchip. The ULPI interface is connected to the Zynq PS USB0 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 EEPROM

A Microchip 24AA025E48 serial EEPROM (U22) contain globally unique 48-bit node address, which are compatible with EUI-48(TM) specification. The device is 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 EEPROM is accessible over I²C bus (see also section I²C interface).

Configuration EEPROM

The TE0783 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.
