Signals, Interfaces and Pins

Board to Board (B2B) connectors

The TE0803 MPSoC SoM has four Board to Board (B2B) connectors with 160 contacts per connector.

Each connector has a specific arrangement of the signal-pins, which are grouped together in categories related to their functionalities and to their belonging to particular units of the Zynq UltraScale+ MPSoC like I/O-banks, interfaces and Gigabit transceivers
or to the on-board peripherals.

Following table lists the I/O-bank signals, which are routed from the MPSoC's PL and PS banks as LVDS pairs or single ended I/O's to the B2B connectors.

Table 2: B2B connector pin-outs of available PL and PS banks of the TE0803-01 SoM

              1) Bank 25 at XCZU2 / XCZU3, else Bank 45 at XCZU4 / XCZU5

              2) Bank 26 at XCZU2 / XCZU3, else Bank 46 at XCZU4 / XCZU5

All MIO banks are powered from on-module DC-DC power rail. All PL I/O banks have separate VCCO input pins in the B2B connectors, valid VCCO should be supplied from the carrier board.

For detailed information about the B2B pin-out, please refer to the Pin-out table. 

The configuration of the I/O's MIO13 - MIO77 are depending on the base-board peripherals connected to these pins.

MGT Lanes

The B2B connectors J1 and J2 provide also access to the MGT banks of the Zynq UltraScale+ MPSoC. There are 8 high-speed data lanes (Xilinx GTH / GTR transceiver) available composed as differential signaling pairs for both directions (RX/TX).

The MGT banks have also clock input-pins which are exposed to the B2B connectors J2 and J3. Following MGT lanes are available on the B2B connectors:

Table 3: B2B connector pin-outs of available MGT lanes of the MPSoC

              1) Bank 224 only available at XCZU4 / XCZU5 MPSoC.

Boot Process

The boot source of the Zynq UltraScale+ MPSoC can be selected via 4 dedicated pins, which generate a 4-bit code to select the boot mode. The pins are accessible on B2B connector J2:

Table 8: Boot mode pins on B2B connector J2

Following boot modes are possible on the TE0803 UltraScale+ MPSoC module by generating the corresponding 4-bit code with pins 'PS_MODE0' ... 'PS_MODE3' (little-endian alignment):

On-board Peripherals

Flash

The TE0803 SoM can be configured with max. 512 MByte Flash memory for configuration and operation. Flash size and type depends on assembly version.

Table 10: Peripherals connected to the PS MIO pins

DDR4 SDRAM

The TE0803-01 SoM is equipped with with four DDR4-2400 SDRAM chips  with up to 8 GByte of memory. The SDRAM chips are connected to the Zynq MPSoC's PS DDR controller (bank 504) via 64-bit wide  data bus.

Refer to the Xilinx Zynq UltraScale+ datasheet DS925 for more information, if the specific Zynq UltraScale+ MPSoC chip on module supports the maximum data transmission rate of 2400 MByte/s.

Configuration EEPROM

The TE0803 (PCB REV02 or newer) contains EEPROMs for general user purposes and mac address. The EEPROMs are provided by Microchip and all have I²C interfaces:

Power and Power-On Sequence

Power Consumption

The maximum power consumption of a module mainly depends on the design which is running on the FPGA.

Xilinx provide a power estimator excel sheets to calculate power consumption. It's also possible to evaluate the power consumption of the developed design with Vivado. See also Trenz Electronic Wiki FAQ.

Table 15: Maximum current of power supplies. *To Be Determined soon with reference design setup.

Power supply with minimum current capability of 3A for system startup is recommended. 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. Except 'PS_BATT', 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.

The TE0803 module equipped with the Xilinx Zynq UltraScale+ MPSoC delivers a heterogeneous multi-processing system with integrated programmable logic and independently operable elements and is designed to meet embedded system power management requirement by advanced power management features. This features allow to offset the power and heat constraints against overall performance and operational efficiency.

This features allowing highly flexible power management are achieved by establishing Power Domains for power isolation. The Zynq UltraScale+ MPSoC has multiple power domains, whereby each power domain requires its own particular external DC-DC converters.

The Processing System contains three Power Domains:

• Battery Power Domain (BBRAM and RTC)
• Full-Power Domain (Application Processing Unit, DDR Controller, Graphics Processing Unit and High-Speed Connectivity)
• Low-Power Domain (Real-Time Processing Unit, Security and Configuration Unit, Platform Management Unit, System Monitor and General Connectivity)

The fourth Power Domain is for the Programmable Logic (PL). If individual Power Domain control is not required, power rails can be shared between domains.

On the TE0803 SoM, following Power Domains can be powered up individually with power rails available on the B2B connectors:

• Full-Power Domain, supplied by power rail 'DCDCIN'
• Low-Power Domain, supplied by power rail 'LP_DCDC'
• Programmable Logic, supplied by power rail 'PL_DCIN'
• Battery Power Domain, supplied by power rail 'PS_BATT'

Each Power Domain has its own "Enabling"- and "Power Good"-signals. The power rail 'GT_DCDC' is only necessary for variants of the TE0803 module with the Xilinx Zynq UltraScale+ ZU4CG or ZU4EV MPSoC to generate the voltages for the available Xilinx GTH unit.

Power Distribution Dependencies

The power rails 'DCDCIN', 'LP_DCDC', 'PL_DCIN', 'PS_BATT' have to be powered up on the assigned pins of the B2B connectors as listed on the section "Power Rails". Except 'PS_BATT' (see section "Recommended Operation Conditions"), all power-rails can be powered up, with 3.3V power sources, also shared, if Power Domain control is not required.

There are following dependencies how the initial voltages of the power rails on the B2B connectors are distributed to the on-board DC-DC converters, which power up further DC-DC converters and the particular on-board voltages:

Figure 3: Power Distribution Diagram (For U4 either TPS548A28RWWR or MPQ8633BGLE-Z is assembled which is up to Trenz Electronic GmbH)

Power-On Sequence Diagram

The TE0803 SoM meets the recommended criteria to power up the Xilinx Zynq UltraScale+ MPSoC properly by keeping a specific sequence of enabling the on-board DC-DC converters dedicated to the particular Power Domains and powering up the on-board voltages.

The on-board voltages of the TE0803 SoM will be powered-up in order of a determined sequence by activating the above-mentioned power rails and the Enable-Signals of the DC-DC converters. The on-board voltages will be powered up at three steps.

1. Low-Power Domain (LPD)
2. Programmable Logic (PL) and Full-Power Domain (FPD)
3. PS GTR transceiver and DDR memory (additionally GTH transceiver at modules with ZU5EV MPSoC)

Hence, those three power instances will be powered up consecutively and the Power-Good-Signals of the previous instance has to be asserted.

Following diagram clarifies the sequence of enabling the three power instances utilizing the DC-DC converter control signals ('Enable', 'Power-Good'), which will power-up in descending order as listed in the blocks of the diagram.

Figure 4: Power-On Sequence Utilizing DC-DC Converter Control Signals

Operation Conditions of the DC-DC Converter Control Signals

The control signals have to be asserted on the B2B connector J2, whereby some of the Power Good Signals need external pull-up resistors.

Table 16: Recommended operation conditions of DC-DC converter control signals

Core voltages and main supply voltages have to reach stable state and their "Power Good" signals have to be asserted before other voltages like bank I/O voltages (VCCOx) can be powered up.

It is important that all PS and PL I/Os are tri-stated at power-on until the "Power Good" signals are high, meaning that all on-module voltages have become stable and module is properly powered up.

See Xilinx datasheet DS925 for additional information. User should also check related base board documentation when intending base board design for TE0803 SoM.

Voltage Monitor Circuit

The voltages 'LP_DCDC' and 'LP_0V85' are monitored by the voltage monitor circuit U41, which generates the POR_B reset signal at Power-On. A manual reset is also possible by driving the MR-pin (J2-83) to GND. Leave this pin unconnected or connect to VDD (LP_DCDC) when unused.
