Boot Process

By default the configuration mode pins of the FPGA are set to QSPI mode, hence the FPGA is configured from serial Flash memory at system start-up. The JTAG interface of the module is provided for storing the initial FPGA configuration data to the QSPI flash memory.

JTAG Interface

Primary JTAG access to the FPGA SoC device U5 is provided through Micro USB2 B connector J9. The JTAG interface is created by the FTDI FT2232H USB2 to JTAG/UART adapter IC U3. 

Optionally 1x6 male pin header J4 can be fitted on board for access to the JTAG interface on board. The pin assignment of header J4 is shown on table below:

On-board Peripherals

Quad SPI Flash Memory

On-module QSPI flash memory (U7) is provided by Winbond Serial Flash Memory W74M64FV with 64 MBit (8 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.

SDRAM

The TEM0001 FPGA module is equipped with a Winbond W9864G6JT 64 MBit (8 MByte) SDRAM chip U2. This SDRAM chip is connected to the FPGA bank 4 and 7 via 16-bit memory interface with 166MHz clock frequency and CL3 CAS latency.

FTDI FT2232H IC

The FTDI chip U3 converts signals from USB2.0 to a variety of standard serial and parallel interfaces. Refer to the FTDI data sheet to get information about the capacity of the FT2232H chip.
FTDI FT2232H chip is used in MPPSE mode for JTAG, 6 I/O's of Channel B are routed to the bank 1 of the FPGA SoC and are usable for example as UART interface.

The configuration of FTDI FT2232H chip is pre-programmed on the EEPROM U9.

System Clock Oscillator

The FPGA SoC module has following reference clocking signals provided by on-board oscillators:

Connectors

All connectors are are for 100mil headers, all connector locations are in 100mil (2.54mm) grid. The module's PCB provides footprints to mount and solder optional pin headers, if those are not factory-fitted on module.

Power and Power-On Sequence

To power-up a module, power supply with minimum current capability of 1A is recommended.

Power Supply

The FPGA module can be power-supplied through Micro USB2 connector J9 with supply voltage 'USB-VBUS' or alternative through pin header J2 with supply voltage 'VIN'.

The TEM0001 module needs one single power supply of 5.0V nominal.

There are following dependencies how the initial voltage of the extern power supply is distributed to the on-board DCDC converters:

Physical Dimensions

Please note that two different units are used on the figures below, SI system millimeters (mm) and imperial system thousandths of an inch(mil). This is because of the 100mil pin headers used, see also explanation below. To convert mils to millimeters and vice versa use formula 100mil's = 2,54mm.

  • Board size: PCB 25mm × 61,5mm. Notice that some parts the are hanging slightly over the edge of the PCB like the the Micro USB2 B connector, which determine the total physical dimensions of the carrier board. Please download the assembly diagram for exact numbers.

  • PCB thickness: ca. 1.65mm

  • Highest part on the PCB without fitted headers and connectors is the Micro USB2 B connector, which has an approximately hight of 3 mm. Please download the step model for exact numbers.
