Overview

Refer to https://wiki.trenz-electronic.de/display/PD/TE0713+TRM for the online version of this manual and the rest of available documentation.

Initial Delivery State

Signals, Interfaces and Pins

Board to Board (B2B) I/Os

FPGA banks and I/O signals connected to the B2B connectors:

JTAG Interface

JTAG access to the Xilinx Artix-7 FPGA and System Controller CPLD devices is provided through B2B connector JM2.

JTAGEN pin in B2B connector JM1 is used to select JTAG access for FPGA or System Controller CPLD:

System Controller I/O Pins

Special purpose pins are connected to System Controller CPLD and have following default configuration:

On-board LEDs

The TE0713-01 module has one LED which is connected to the System Controller CPLD. Once FPGA configuration has completed, it can be used by the user's design. 

Clocking

On-board Si5338 clock generator chip is used to generate clocks with 25 MHz oscillator connected to the pin IN3 as input reference. There is a I²C bus connection between the FPGA bank 14 (master) and clock generator chip (slave) which can be used to program output frequencies. See the reference design for more information.

On-board Peripherals

32 MByte Quad SPI Flash Memory

On-board QSPI flash memory S25FL256S (U14) 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.

System Controller CPLD

System Controller CPLD (Lattice Semiconductor MachXO2-256HC, U3) is used to control FPGA configuration process. The FPGA is held in reset (by driving the PROG_B signal low) until all power supplies have stabilized.

By driving signal RESIN to low you can reset the FPGA. This signal can be driven from the user’s baseboard PCB via the B2B connector JM2 pin 18.

Input EN1 is also gated to FPGA reset, should be open or pulled up for normal operation. By driving EN1 low, on-board DC-DC converters will be not turned off.

User can create their own System Controller design using Lattice Diamond software. Once created it can be programmed into CPLD via JTAG interface.

DDR3L SDRAM

The TE0713-01 SoM has two 4 Gbit volatile DDR3 SDRAM ICs (U15 and U19) for storing user application code and data.

• Part number: IM4G16D3FABG-125I
• Supply voltage: 1.35V
• Organization: 32M words x 16 bits x 8 banks
• Memory speed: limited by Xilinx Artix-7 speed grade and MIG

 Configuration of the DDR3 memory controller in the FPGA should be done using the MIG tool in the Xilinx Vivado Design Suite IP catalog.

USB 3.0 to FIFO Bridge

TE0713-01 is equipped with the FTDI FT600Q high performance USB 3.0-to-FIFO interface bridge chip.

Power and Power-On Sequence

Power Supply

Single 3.3V power supply (for both VIN and 3.3VIN power rails) with minimum current capability of 3A for system startup is recommended.

Power Consumption

Typical module power consumption is between 2-3W. Exact power consumption is to be determined.

TE0713-01 module can also be powered by split 5V/3.3V power sources if preferred. In such case apply 5V to B2B connectors VIN pins and 3.3V to 3.3VIN pins, although lowest power consumption is achieved when powering the module from single 3.3V supply. When using split 5V/3.3V supplies the power consumption (and heat dissipation) will rise due to the DC-DC converter efficiency (it decreases when VIN/VOUT ratio rises).

Power-On Sequence

For the 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 baseboard I/Os are 3-stated at power-on until System Controller 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 Xilinx datasheet DS181 - "Artix-7 FPGAs Data Sheet: DC and AC Switching Characteristics" for additional information. User should also check related baseboard documentation when choosing baseboard design for TE0713 module.
