Interfaces and Pins

Micro SD Card Socket

Micro SD Card card socket is not directly wired connected to the B2B connector pins, but through a Texas Instruments TXS02612 SDIO Port Expander , which is needed for voltage translation due to different voltage levels of the Micro SD Card and MIO-bank of the Xilinx Zynq-module. The Micro SD Card card has 3.3V signal voltage level , but the MIO-bank on the Xilinx Zynq-module has VCCIO while Xilinx Zynq MIO bank uses 1.8V for VCCIO.

Channel USB to UART/FIFO

The TE0705 Carrier Board carrier board has on-board USB 2.0 High Speed high-speed to UART/FIFO IC FT2232HQ FT2232H from FTDI. Channel A can be used as JTAG - Interface (MPSSE) to program the System - Controller - CPLD, . Channel B can be used as UART - Interface routed to CPLD. There are also 6 additionally additional bus-lanes available for user-specific use. The FT2232HQ-Chip can also be used as FIFO in FT245 asynchronous mode.

There is also a standard 256 Byte -byte serial EEPROM connected to the FT2232HQ-chip available to store custom configuration settings. EEPROM settings can be changed using FTDI provided tools that can be downloaded from FTDI website. See FTDI website for more informationFT2232H chip pre-programmed with license code to support Xilinx programming tools.

USB Interface

The TE0705 carrier board has two physical USB - connectors:

• J7 as mini-USB - connector wired to on-board FTDI FT2232HQ FT2232H chip.
• J12 as micro-USB - connector wired to B2B connector JB3 (usually there is usually an USB - transceiver on the SoMsSoM).

JTAG Interface

JTAG access to the CPLD and Xilinx Zynq-module on-board System Controller CPLD and SoM is provided via Minimini-USB JTAG Interface interface J7 (FTDI FT2232H) and controlled by DIP switch S3-3.The JTAG port of the CPLD is enabled by setting switch S3-3 labeled as "ENJTAG" to the OFF-position

LEDs

There are eight LEDs (D6, D7, D8, D9, D4, D5, D14, D15) available to the user. All LEDs are red colored and connected mapped to the on-board System - Controller - CPLD. Their functions are programmable and depend on the firmware of the System - Controller - CPLD. For detailed information, please refer to the documentation of the TE0705 System - Controller - CPLD.

4-bit DIP-switch S4

Additionally , on the TE0705 Carrier Board there is a 4-bit DIP-switch S3 (see (16) in Figure 1) available. The signals of the switch are routed to carrier board's System-Controller-CPLD and are fully user-configurable depending on a customer developed CPLD-S4 available routed to the System Controller CPLD which function is user configurable via custom CPLD firmware. Please refer to the documentation of the TE0705 System - Controller - CPLD to get information how to put these user-switches in operation documentation for more information.

All switch S4 pins are connected to 3.3V pull-up resistors in OFF position.

User

...

Push-Buttons

On the TE0705 Carrier Board there are two push buttons (S1 and S2) and are routed to the System - Controller - CPLD and available to the user. The default mapping of the push buttons is as follows:

The Table 2: Description of the standard functionality of the user push-buttons S1 and S2.

The functionality of the push buttons depends on the CPLD - firmware. For detailed information of the function of the push buttons, please refer to the documentation of the TE0705 System - Controller - CPLD.

Ethernet

The TE0701 TE0705 Carrier Board has a RJ45 Gigabit Ethernet MagJack (J14) with two LEDs.

...

PHY LEDs are not connected directly to the module's B2B connectors as the 4x5 module TE 4 x 5 cm modules have no dedicated PHY LED pins assigned. PHY LEDs are connected to the TE0705 System - Controller - CPLD, that can route those LEDs to some the module's I/O IO Pins. In that case, the CPLD has to map the PHY LEDs to corresponding module's IO pins.

See documentation of the TE0705 System - Controller - CPLD to get information of the function of the PHY LEDs.

IDC header sockets J5 and J6

On the TE0705 there two IDC header available for access to SoM's PL IO-bank pins

J5 and J6 sockets signal routing is done as differential pairs for pins 1-3, 2-4, 5-7, 6-8. The differential pairs are operable with VCCIO-voltage VIOTB.Please use Master Pinout Table table as primary reference for the pin mapping information, hence 4 LVDS pairs are possible on this sockets. The differential pairs are operable with max. VCCIO voltage VIOTB.

IDC header socket J1

Zynq-moduleIDC header J1 provides access to SoM's MIO0PL IO-bank pins, whereby 6 pins (net name: 'MIO10' to 'MIO15') of this header are also routed to the System Controller CPLD.

If Zynq module is mounted on the TE0705 carrier board, the pins of this header are routed to the corresponding pins of the PS logic of the SoM: MIO0-bank pins MIO0, MIO9-MIO15 are accessible on header J1 and operable with max. VCCIO voltage 3.3V.

MIO0, MIO9-MIO15 are accessible on socket J1. Maximal VCCIO-voltage is 3.3V on this socket. An exception here is the 'MIO12'-pin, which is buffered with a Schmitt-Trigger -Buffer buffer with a Hystersis hysteresis of 5.0V.

IDC IDC header socket J2

Zynq-module12-pin header J2 provides access to SoM's PL IO-bank pins are accessible on socket J2. The IO-signals are routed from this socket to B2B-connector JB3 and are only single-ended IOs, hence this signal-pins are not usable as differential pairs. Maximal VCCIO-voltage is VIOTB on this socket. Operable with fixed (3.3V) or adjustable VCCIO voltage VIOTB (Single ended IOs, not usable as LVDS pairs).

40-pin headers J11 and J13

40-Pin-Header pin header J11 and J13  for provide access to Zynq-moduleSoM's PL IO-bank - pins on routed to B2B-connectors JB1 and JB2. Operable with fixed (3.3V) or adjustable VCCIO - voltage VIOTB (Single ended IOs, not usable as LVDS - pairs, only single-ended IOs).

Configuring VCCIO 

On the TE0705 carrier board different VCCIO configurations can be chosen are selectable by jumper J21 and DIP-switch S3.

The purpose of the jumper and the DIP-switch S3 of the Carrier Board will be explained in the following sections.

...

VCCIO

...

Voltage Level DIP-Switch S3

There is the possibility to select the module's PL IO-bank's supply voltage VIOTB to fixed adjustable voltages VADJ. Therefore, the jumper J21 has to be set to the position 1, 2-3, to connect the pins 'VIOTB' and 'ADJ'. On position 1-2, 3, the supply voltage VIOTB will be fixed to 3.3V

Table 3 shows the switch-configuration of the DIP-switch S3 to set the voltage VADJ.

Note: The configuration of VADJ depends on the used firmware of the System-Controller-CPLD. For detailed information, refer to the documentation of the TE0705 System-Controller-CPLD.

With jumper J21, user can select between two different power sources for SoM PL IO banks supply voltage VIOTB. If set to position 1-2, fixed 3.3V is selected as VIOTB source. If set to position 2-3, FMC_VADJ is selected as VIOTB source. Voltage level of FMC_VADJ depends on the settings of DIP-switch S3, see table below:

Configuring Power Supply of the Micro USB Connector (Device, Host or Configuring Power Supply of the Micro USB Connector (Device, Host or OTG Modes) 

The TE0705 carrier board can be configured as a USB host device. Hence, it must provide from 5.25V to 4.75V to the board side of the downstream connection (micro USB port on J12). To provide sufficient power, a TPS2051 power distribution switch is located on the carrier board in between the 5V power supply and the Vbus signal of the USB downstream port interface. If the output load exceeds the current-limit threshold, the TPS2051 limits the output current and pulls the overcurrent over-current logic output (OC_n) low, which is routed to the on-board CPLD. The TPS2051 is put into operation by setting J19 CLOSED. J20 provides an extra 100µF decoupling capacitor (in addition to 10µF) to further stabilize the output signal. Moreover, a series terminating resistor of either 1K (J9: 1-2, 3) or 10K (J9: 1, 2-3) is selectable on the "USB-VBUS" signal. Both signals, USB-VBUS and VBUS_V_EN (that enables the TPS2051 on "high") are routed (as well as the corresponding D+/- data lines) via the on-board connector directly to the USB 2.0 high-speed transceiver PHY on the mounted SoM, which is, in turn, connected to the Zynq FPGA. In summary, the default jumper settings are the following: J9: 1-2, 3 (1K series terminating resistor); J19: CLOSED (TPS2051 in operation); J20: CLOSED (100 µF added).

Additionally, the TE0705 carrier board is equipped with a second mini USB port J7 that is connected to a "USB to multi-purpose UART/FIFO IC" from FTDI (FT2232HQFT2232H) and provides a USB-to-JTAG interface between a host PC and the TE0705 carrier board and the Zynq-modulemounted SoM, respectively. Because it acts as a USB function device, no power switch is required (and only a ESD protection must be provided) in this case.

Power On Reset (POR)

On the TE0705 the 5.0V and 3.3V power supply rails are generated by high performance DC-DC-converters from the external 12V supply. While the 3.3V plane supplies several on-board components (e.g., Lattice CPLD and FTDI Dual USB UART/FIFO IC), the 5V plane is mainly provided to power supply of the module to be carried (e.g., TE0720 Zynq SoC module). For the latter, however, special considerations must be taken (see TE0720 Power Supply). Therefore, the on-module system controller (SC) must be provided with information about the power-on-reset (POR) process, namely, the following control signals EN1, RESIN, and NOSEQ. And the SC provides, in turn, the status signal PGOOD down to the on-board System-Controller-CPLD.
