512 Mbyte DDR3L SDRAM
The TE0728 SoM has two 512 GByte volatile DDR3 SDRAM IC for storing user application code and data.
- Part number: NT5CC256M16DP Nanya
- Supply voltage: 1.35V
- Speed: 1600 Mbps
- NOR Flash
- Temperature: 0C~95C
Configuration of the DDR3 memory controller in the FPGA should be done using the MIG tool in the Xilinx Vivado Design Suite IP catalog.
Ethernet
There are two 100 MBit Extreme Temperature Ethernet PHY's DP83848-EP provided by Texas Instrument on the board. Datasheet is provided TI website, Literature number SNLS208H. Both PHY's are connected with all I/O Pins to FPGA Bank 34 (VCCIO = 3.3V). PHY Clock 25 MHz source is provided from MEMS Oscillator. There is no sharing of signals for the two PHY's.
PUDC pin is connected with pull-up to 3.3V those pre-configuration pull-ups are disabled by default. Strapping resistor exist to change the PUDC mode.
Both PHY's must be operated in MII Mode, other modes are not supported. It is possible to use PS ENET0 or ENET1 via EMIO routing or Ethernet IP Cores implemented in PL Fabric.

| RESET_N | M15 | R16 | on-chip | It is recommended to configure FPGA I/O as input with Pullup or as output (active low PHY Reset). |
It is recommended to add IOB TRUE constraint for the MII Interface pins.
When connecting the PHY's to Zynq PS ETH0, ETH1 EMIO GMII Interfaces it is recommended to use GMII to MII Wrap IP Core. This IP core maps the EMIO GMII to external MII Interface.
CAN Transceiver
The SN65HVD230Q, controller area network (CAN) transceivers are designed for use with the Texas Instruments TMS320Lx240x 3.3-V DSPs with CAN controllers. The datasheet is avaiable in Texas Instrumens website. They are intended for use in applications employing the CAN serial communication physical layer in accordance with the ISO 11898 standard. Each CAN transceiver is designed to provide differential transmit capability to the bus and differential receive capability to a CAN controller at speeds up to 1 Mbps. Temperature must be in range of -40C~125C.
