Signals, Interfaces and Pins

System Controller I/O Pins

Special purpose pins used by TE0729

Boot Modes

TE0729 supports primary boot from

• JTAG
• SPI Flash
• SD Card

Boot from on-board eMMC is also supported as secondary boot (FSBL must be loaded from SPI Flash).

The boot modes are controlled by the Pins 'BOOT1' and 'BOOT2' on the board to board (B2B) connector.

JTAG

JTAG access to the Xilinx Zynq-7000 device is provided by connector J2.

Peripherals

LED's

There are 3 LED's on TE0729:

Ethernet

The TE0715 is populated with a Marvell Alaska 88E1512 Gigabit Ethernet PHY. The Ethernet PHY RGMII Interface is connected to the Zynq Ethernet0 PS GEM0. The I/O Voltage is fixed at 1.8V for HSTL signaling. 

SGMII (SFP copper or fiber) can be used directly with the Ethernet PHY, as the SGMII pins are available on the B2B connector JM3.

The reference clock input of the PHY is supplied from an on board 25MHz oscillator (U9), the 125MHz output clock is connected to IN5 of the PLL chip (U10).  

PHY connection:

Note: LED1 is connected to PL via level-shifter implemented in system controller CPLD.

USB

The USB PHY USB3320 from Microchip is used on the TE0715. The ULPI interface is connected to the Zynq PS USB0. The I/O Voltage is fixed at 1.8V.

The reference clock input of the PHY is supplied from an on board 52MHz oscillator (U15).  

PHY connection:

The schematic for the USB connector and required components is different depending on the USB usage. USB standard A or B connectors can be used for Host or Device modes. A Mini USB connector can be used for USB Device mode. A USB Micro connector can be used for Device mode, OTG Mode or Host Mode.

RTC

An Intersil temperature compensated real time clock IC ISL12020M is used for timekeeping (U16). Battery voltage must be supplied to the module from the main board.

Battery backed registers are accessed at I2C slave address 0x6F.

General purpose RAM is accessed at I2C slave address 0x57.

This RTC IC is supported in Linux so it can be used as hwclock device.
