Procurement Notes

Verify the specific assembly variant against the datasheet to ensure compatibility with required memory configurations and temperature ranges. Confirm that the initial delivery state meets project needs, as flash and eMMC may arrive unprogrammed while the CPLD contains firmware. Check for any product change notifications regarding component substitutions or revision updates before finalizing procurement.

Selection Notes

Select this module when a compact form factor is required alongside significant processing power and peripheral integration. The inclusion of both DDR4 and eMMC supports complex boot sequences and large data handling. Ensure the carrier board design accommodates the specific B2B connector mating heights and voltage levels defined in the technical specifications.

Part Context

This module belongs to the TE0823 family of 4x5 cm System-on-Modules designed by Trenz Electronic. These modules are engineered for mechanical and electrical compatibility within their series, allowing for scalable design transitions. The TE0823 specifically targets applications demanding robust performance in constrained spaces with industrial reliability requirements.

Replacement Considerations

Consult the manufacturer's documentation for current alternatives if discontinuation occurs. Verify pinout and mechanical compatibility with existing carrier boards before transitioning to successor models or different SoC variants within the same module family.

FAQ

How is JTAG access managed on the TE0823?

JTAG access to the Xilinx Zynq UltraScale+ is routed through the Lattice MachXO2 CPLD via the B2B connector JM2. The JTAGEN signal determines whether the connection targets the SoC or the CPLD.

What clock sources are available on the module?

The module integrates three MEMS oscillators providing frequencies of 25 MHz, 52 MHz, and 80 MHz to support various peripherals including the Ethernet PHY, USB transceiver, and programmable clock generator.

Can the Ethernet interface operate in SGMII mode?

Yes, the on-board Marvell Alaska 88E1512 PHY supports SGMII mode. The relevant pins are accessible via the B2B connector JM3, allowing direct connection to SFP copper or fiber modules.
