TE0782 TRM

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. It is equipped with a Xilinx Zynq-7 (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.

Signals, Interfaces and Pins

System Controller CPLD I/O-Pins

Special purpose pins to configure and operate the System Controller CPLD (IC U14) used by TE0782:

Small CPLD controls some functions of the SoM, this CPLD can be updated by the end user if support is designed in on customer base.

Boot Modes

TE0782 supports primary boot from

• SPI Flash

Boot from on-board eMMC is also supported as secondary boot (FSBL must be loaded from SPI Flash).

JTAG Bootmode is always possible no matter the Zynq Boot mode selected.

JTAG

JTAG access to the Xilinx Zynq-7000 device is provided by connector J3.

CPLD-JTAG access to the Xilinx Zynq-7000 device is provided by connector J3.

Clocking

Silabs Multisynth PLL Si5338 can deliver GT reference clocks to all 4 GT Banks. Additionally a GT Reference clock can be generated on the base board for any of the 4 GT Banks. There is reference clock available on the TE0782 for Si5338, optionally external reference clock can be supplied from the base.

Processing System (PS) Peripherals

Default MIO mapping

Pin Definitions

Pins named _vrn and _vrp are connected to ZYNQ PL HP Bank special purpose pins VRN/VRP. If needed they can be connected to DCI calibration resistors on the base. If not, then those pins can be used as general purpose I/O.

Bank B35 has 100 ohm DCI calibration resistors installed on TE0782, it is also possible to "borrow" the DCI calibration from B35 for banks B34, and B33. For detailed usage of the DCI check Xilinx documentation.

I2C Interface

The on-board I2C components are connected to BANK35, Pin L15 (I2C_SDA) and to BANK35, Pin L14 (I2C_SCL).

Ethernet

The TE0782 is equipped with two Marvell Alaska 88E1512 Gigabit Ethernet PHYs (U18 (ETH1) and U20 (ETH2)). The transceiver PHY of ETH1 is connected to the Zynq PS Ethernet GEM0. The I/O Voltage is fixed at 1.8V. The reference clock input for both PHYs is supplied from an on board 25MHz oscillator (U11).

ETH1 PHY connection:

ETH2 PHY connection:

USB

The TE0782 is equipped with two USB PHY's USB3320 from Microchip (U4 (USB0) and U8 (USB1)). The ULPI interface of USB0 is connected to the Zynq PS USB0, ULPI interface of USB1 to Zynq PS USB1. The I/O Voltage is fixed at 1.8V.

The reference clock input of both PHY's is supplied from an on board 52MHz oscillator (U7).  

USB0 PHY connection:

USB1 PHY connection:

The schematic for the USB connector and required components is different depending on the USB usage. USB standard A or B connectors can be used for Host or Device modes. A Mini USB connector can be used for USB Device mode. A USB Micro connector can be used for Device mode, OTG Mode or Host Mode.

RTC

An Intersil temperature compensated real time clock IC ISL12020MIRZ is used for timekeeping (U17). Battery voltage must be supplied to the module from the main board.

Battery backed registers are accessed at I2C slave address 0x57.

General purpose RAM is accessed at I2C slave address 0x6F.

This RTC IC is supported in Linux so it can be used as hwclock device.

PLL

The TE0782 is also equipped with a Silicon Labs I2C-programmable clock generator Si5338A (U2). The Si5338 can be programmed using the I2C-bus, to change the frequency on its outputs. It is accessible on the I2C slave address 0x70.

PLL connection:

MAC-Address EEPROM's

Two Microchip 24AA025E48 EEPROM's (U22 and U24) are used on the TE0782. They contain globally unique 48-bit node addresses, that are compatible with EUI-48(TM) and EUI-64(TM). The devices are organized as two blocks of 128 x 8-bit memory. One of those blocks stores the 48-bit node address and is write protected, the other block is available for application use. Those are accessible by the I2C slave address 0x50 for MAC-Address1 (U22), 0x51 for MAC-Address2 (U24) .

Power

Input Power Supply

Bank Voltages

Power-up sequence at start-up

The Trenz TE0782 SoM is equipped with two quad DC/DC-voltage-regulators to generate the required on-board voltages with the values 1V, 3.3V, 1.8V, 1.2V_MGT, 1V_MGT.

There are also additional voltage regulators on board to generate the voltages 1.5V, VTT, VTTREF and 1.8V_MGT.

On this SoM the sequence of powering up of the required on-board voltages is handled internally by the system controller CPLD processing the "POWER GOOD"-signals from the voltage-regulators.

The "POWER GOOD"-signals can be checked on the system controller CPLD.

Pay attention to the voltage level of the I/O-signals, which must not be higher then VCCIO+0.4V.
