Signals, Interfaces and Pins

Board to Board (B2B) connectors

The TE0808 MPSoC UltraSoM 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 peripheral ICs of the SoM.

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.

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

MGT lanes

The B2B connector J1 and J2 provide also access to the MGT-banks of the Zynq Ultrascale+ MPSoC. There are 20 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:

Quad-SPI Flash memory

The TE0808-03 SoM is equipped with two Serial Flash Memory with up to 512 Mbyte storage capacity each. The flash memory ICs with the schematic designators U7 and U17 are connected to bank 500 (PSMIO) of the Zynq MPSoC module via QSPI interface, enabling a 8-Bit width databus connection.

Following table shows the mapping of the MIO-pins to the flash memory ICs.

Table 7: Flash memory QSPI-interface

DDR4 SDRAM

The TE0808-03 UltraSoM is equipped with with four DDR4-2400 SDRAM modules with up to 8 Gbyte memory density. The SDRAM modules are connected to the Zynq MPSoC's PS DDR-controller (bank 504) with a 64-bit databus width.

LEDs

TE0808 has one red LED (D1) which reflects MPSoC's 'DONE' signal. This LED goes ON when power has been applied to the module and stays ON until MPSoC's programmable logic is configured properly.

Clocking

Programmable Clock Generator

Power and Power-On Sequence

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. 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 TE0808-03 module 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 particular extern DCDC 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 TE0808-03 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"-signal. The power rail 'GT_DCDC' is necessary for generating the supply voltages for the high speed Gigabit Transceivers units of the Zynq Ultrascale+ MPSoC.

Power-On Sequence utilizing DCDC control signals

To power up the TE0808-03 SoM properly, a specific sequence must be kept of enabling the on-board DCDC converters dedicated to the particular Power Domains and powering up the on-board voltages.

The first activated Power Domain is the Low-Power Domain. Therefore, the power rail 'LP_DCDC' have to be powered up and the Enable-signal 'EN_LPD' (pin J2-108, 7V max.) have to be asserted. The resulting Power-Good-Signal 'LP_GOOD' (pin J2-106) will go high after the voltages of the Low-Power Domain are properly powered up.

Figure 3: Low-Power Domain

The second activated Power Domain is the Programmable Logic. Therefore, the power rail 'PL_DCIN' have to be powered up and the Enable-signal 'EN_PL' (pin J2-101) have to be asserted by pulling this pin up to the voltage 'LP_DCDC' or left floating (drive to GND for disabling). The resulting Power-Good-Signal 'PG_PL' (pin J2-104) will go high after the voltages of the Programmable Logic Domain are properly powered up. The signal 'PG_PL' needs an extern pull-up (max. voltage 'GT_DCDC').

Figure 4: Programmable Logic Domain

Also as second activated Power Domain is the Full-Power Domain. Therefore, the power rail 'DCDCIN' have to be powered up and the Enable-signals 'EN_FPD' (pin J2-102) and 'EN_DDR' (J2-112) have to be asserted (max. voltage 'DCDCIN'). The resulting Power-Good-Signals 'PG_FPD' (pin J2-110) and 'PG_DDR' (J2-114) will go high after the voltages of the Full-Power Domain are properly powered up. In the following, the PSGT voltages (see figure 3) can be powered up by asserting the Enable-signal 'EN_PSGT' (pin J2-84, max. voltage 'DCDCIN'). The resulting Power-Good-Signal 'PG_PSGT' (pin J2-82) needs an extern pull-up (max. 6V).

Figure 5: Full-Power Domain

The supply voltages for the MGT units of the MPSoC will be powered up last. Therefore, the power rail 'GT_DCDC' have to be powered up and the Enable-signals 'EN_GT_R' (pin J2-95), 'EN_GT_L' (pin J2-79) and 'EN_PLL_PWR' (J2-77, 7V max.) have to be asserted (max. voltage 'GT_DCDC'). The resulting Power-Good-Signals 'PG_GT_R' (pin J2-91), 'PG_GT_L' (pin J2-97) and 'PG_PLL_1V8' (J2-80) will go high after the supply voltages of the MGT units are properly powered up. The three Power-Good-Signals need an extern pull-up (max. 6V).

Figure 6: Powering up MGT supply voltages

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

Figure 7: Voltage monitor circuit

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's I/O voltages (VCCOx) can be powered up.

It is important that all PS and PL I/Os are 3-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.
