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 ICs of the UltraSoM.

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

Quad-SPI Flash memory

The TE0808-03 UltraSoM is equipped with two Micron Serial NOR Flash Memory with 256 Mbit (32 Mbyte) storage capacity. 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.

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

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.

Power and Power-On Sequence

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 is achieved by establishing Power Domains for power isolation. The Zynq Ultrascale+ MPSoC is composed of multiple power domains, whereby each power domain requires their particular extern DCDC converters.

The Processing System contains three Power Domains:

• Battery Power Domain, needed for BBRAM and RTC
• Full-Power Domain, needed for Application Processing Unit, DDR Controller, Graphics Processing Unit and High-Speed Connectivity
• Low-Power Domain, needed for 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.

The following diagram shows the sequence of enabling the on-board DCDC converters dedicated to the particular Power Domains and powering up the needed voltages.

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' generates the supply voltages for the high speed Gigabit Transceivers units of the Zynq Ultrascale+ MPSoC.

For the absolute maximum ratings and the recommended operating conditions of the power rails, see section 'Technical Specifications'.
