EEPROM
The Microchip Technology Inc. 24xx64 is a 64 Kbit Electrically Erasable PROM. The device is organized as a single block of 8K x 8-bit memory with a 2-wire serial interface. Lowvoltage design permits operation down to 1.7V, with standby and active currents of only 1 μA and 3 mA, respectively. It has been developed for advanced, lowpower applications such as personal communications or data acquisition. The 24xx64 also has a page write capability for up to 32 bytes of data. Functional address lines allow up to eight devices on the same bus, for up to 512 Kbits address space.

DDR3 SDRAM
The TE0728 SoM has two 512 MByte volatile DDR3 SDRAM IC for storing user application code and data.
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 provided by Texas Instrument on the board. Datasheet is provided TI website. 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.

Ethernet PHY to Zynq SoC connections
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
Controller Area Network (CAN) transceivers are designed for use with the Texas Instruments TMS320Lx240x 3.3-V DSPs with CAN controllers. The datasheet is available in TI website. 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.

Low Quiescent Current Programmable Delay Supervisory Circuit
The microprocessor supervisory circuits monitor system voltages from 0.4 V to 5 V, asserting an open-drain RESET signal when the SENSE voltage drops below a preset threshold or when the manual reset (MR) pin drops to a logic low. The RESET output remains low for the user adjustable delay time after the SENSE voltage and MR return above their thresholds. Datasheet is available in Texas Instruments website.
Low Dropout Linear Regulator
The low-dropout (LDO) provides an easy-to-use robust power management solution for a wide variety of applications. User programmable soft-start minimizes stress on the input power source by reducing capacitive inrush current on start-up. The soft-start is monotonic and well- suited for powering many different types of Monitoring or Provides a Sequencing Signal processors and ASICs. The enable input and power for Other Supplies good output allow easy sequencing with external regulators. This complete flexibility permits the user to configure a solution that meets the sequencing Voltage Startup requirements of FPGAs, DSPs, and other applications with special start-up requirements.

Power-On Sequence

Power Sequence
The PS and PL power supplies are fully independent. PS power supplies (VCCPINT, VCCPAUX, VCCPLL, VCCO_DDR, VCCO_MIO0, and VCCO_MIO1) can be powered before or after any PL power supplies. The PS and PL power regions are isolated to prevent damage. The recommended power-on sequence is VCCPINT, then VCCPAUX and VCCPLL together, then the PS VCCO supplies (VCCO_MIO0, VCCO_MIO1, and VCCO_DDR) to achieve minimum current draw and ensure that the I/Os are 3-stated at power-on. The PS_POR_B input is required to be asserted to GND during the power-on sequence until VCCPINT, VCCPAUX and VCCO_MIO0 have reached minimum operating levels to ensure PS eFUSE integrity.
