The schematics 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.
I2C Interface
The I2C interface on the B2B connector J2 pins 119 (I2C_33_SCL) and 121 (I2C_33_SDA) have PS_3.3V as a reference voltage.
Except the RTC (U24), all remaining I2C slave devices are operating with the reference voltage PS_1.8V via voltage level translating (3.3V ↔ 1.8V) I2C bus repeater (U17).
I2C addresses for on-board devices are listed in the table below:

Boot Process
TE0745 module supports different boot modes which are configurable by the control line 'BOOTMODE' and 'BOOTMODE_1'. The line 'BOOTMODE' is available on B2B connector pin J2-133, the line 'BOOTMODE_1' is connected to the System Controller CPLD on bank 1, pin 21.
The current boot mode will be set by the MIO pins MIO3...MIO5. The control line 'BOOTMODE' is connected to the 'MIO4' pin, 'BOOTMODE_1' to 'MIO5'.

MAC Address EEPROM
A Microchip 24AA025E48 serial EEPROM (U23) contains a globally unique 48-bit node address, which is compatible with EUI-48(TM) specification. The device is organized as two blocks of 128 x 8-bit memory. One of the blocks stores the 48-bit node address and is write protected, the other block is available for application use. It is accessible over I2C bus with slave device address 0x53.
RTC - Real Time Clock
An temperature compensated Intersil ISL12020M is used as Real Time Clock (U24). Battery voltage must be supplied to the clock from the base board via pin 'VBAT_IN' (J1-146). Battery backed registers can be accessed over I2C bus at slave address 0x6F. General purpose RAM of the RTC can be accessed at I2C slave address 0x57. RTC IC is supported by Linux so it can be used as hwclock device. The interrupt line 'RTC_INT' of the RTC is connected to System Controller CPLD bank 3 pin 4.
Programmable PLL Clock (Phase-Locked Loop)
There is a Silicon Labs I2C programmable quad PLL clock generator Si5338A (U16) on-board. It's output frequencies can be programmed by using the I2C-bus with address 0x70.
A 25 MHz (U21) oscillator is connected to pin 3 (IN3) and is used to generate the output clocks.
Once running, the frequency and other parameters can be changed by programming the device using the I2C-bus connected between the Zynq module (master) and reference clock signal generator (slave).

Power and Power-On Sequence
Power Supply
Power supply with minimum current capability of 3A for system startup is recommended.
Power Consumption
...
Table 14: Maximum current of power supplies. *to be determined soon with reference design setup.
For the lowest power consumption and highest efficiency of on board DC-DC regulators it is recommended to powering the module from one single 3.3V supply. All input power supplies 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-On Sequence
The on-board voltages of the TE0745 SoC module will be powered-up in order of a determined sequence after the external voltages 'PL_VIN', 'PS_VIN' and 'PS_3.3V' are available.
Warning |
---|
To avoid any damage to the SoC module, check for stabilized on-board voltages in steady state before powering up the SoC's I/O bank voltages VCCO_x. |
Core voltages and main supply voltages have to reach stable state and their "Power Good"-signals have to be asserted before other voltages like PL bank's I/O voltages can be powered up.
It is important that all baseboard I/Os are 3-stated at power-on until the "Power Good"-signals 'PWR_PS_OK' (J2-139) and 'PWR_PL_OK' (J2-135) are high, meaning that all on-module voltages have become stable and module is properly powered up.
Following diagram clarifies the sequence of enabling the particular on-board voltages:
