Table 7: Quad SPI interface signals and connections.

I2C Interface

There are two PL bank 65 I/O pins (PLL_SCL and PLL_SDA) reserved as I²C bus connected to the Si5338 PLL quad clock generator. Default Si5338 PLL chip I²C bus slave address is 0x70.

Additionally, two PL bank 65 I/O pins (B65_SCL and B65_SDA) connected to the B2B connector JM1 can be used for external I²C connectivity, otherwise these pins are ordinary I/Os.

On-board Peripherals

System Controller CPLD

The System Controller CPLD (U18) is provided by Lattice Semiconductor LCMXO2-256HC (MachXO2 Product Family). The  SC-CPLD is the central system management unit where essential control signals are logically linked by the implemented logic in CPLD firmware, which generates output signals to control the system, the on-board peripherals and the interfaces. Interfaces like JTAG and I²C between the on-board peripherals and to the FPGA module are by-passed, forwarded and controlled by the System Controller CPLD.

Other tasks of the System Controller CPLD are the monitoring of the power-on sequence and to display the programming state of the FPGA module.

For detailed information, refer to the reference page of the SC CPLD firmware of this module.

Quad SPI Flash Memory

On-board QSPI flash memory (U6) on the TE0841-01 is provided by Micron Serial NOR Flash Memory N25Q256A with 256-Mbit (32-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. 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.

Power and Power-On Sequence

Power Supply

Single 3.3V power supply with minimum current capability of 4A for system startup is recommended.

Power Consumption

...

Table 11: Typical power consumption.

 * TBD - To be determined.

Power-On Sequence

For 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 CPLD 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 also Xilinx datasheet DS892 for additional information. User should also check related baseboard documentation when choosing baseboard design for TE0720 module.

Power and Power-On Sequence

<!--
If power sequencing and distribution is not so much, you can join both sub sections together
  -->

Power Consumption

The maximum power consumption of a module mainly depends on the design running on the FPGA.

Xilinx provide a power estimator excel sheets to calculate power consumption. It's also possible to evaluate the power consumption of the developed design with Vivado. See also Trenz Electronic Wiki FAQ.

Table 12: Typical power consumption

 * TBD - To Be Determined soon with reference design setup.

Single 3.3V power supply with minimum current capability of 4A for system startup is recommended.

For the lowest power consumption and highest efficiency of the on-board DC-DC regulators it is recommended to power the module from one single 3.3V supply. All input power supplies should have a nominal value of 3.3V. Although the input power supplies can be powered up in any order, it is recommended to power them up simultaneously.

Power Distribution Dependencies

See also Xilinx datasheet DS892 for additional information. User should also check related base board documentation when intending base board design for TE0841 module.

Power-On Sequence

The TE0841 SoM meets the recommended criteria to power up the Xilinx FPGA properly by keeping a specific sequence of enabling the on-board DC-DC converters dedicated to the particular functional units of the FPGA chip and powering up the on-board voltages.

Following diagram clarifies the sequence of enabling the particular on-board voltages, which will power-up in descending order as listed in the blocks of the diagram:
