Products Affected

This change affects all Trenz Electronic TE0729 SoMs: TE0729-02*.

...

Type: Schematic Change

Reason: Improve name handlingnaming.

Impact: None.

#6 Changed power sequencing.

...

Reason: Follow AMD and Texas Instruments recommendation.

Impact: Voltage rails start in other orderCheck that the new power-up sequence fits your requirements. Voltage supervisor (U4) enables 1V voltage rail (DCDC U23) via signal EN_Module. 1V DCDC (U23) enables 1.8V voltage rail (DCDC U25) via signal PG_1V0. 1.8V DCDC (U25) enables 2.5V (DCDC U24) and DDR_VDD (DCDC U26) voltage rails via signal PG_1V8. Voltage rail 3.3V (load switch Q1) is logical AND-enabled via power good signal PG_2V5_3V3 from voltage rail 2.5V DCDC (U24) and DDR_VDD DCDC (U26) via diode (D4) and CPLD (U6) signal EN_3V3 via diode (D5).

#7 Added bidirectional level shifter (U7) and capacitors (C185, C186) to separate power domains for signal FPGA_IO. Added fallback resistor (R91).

Type: Schematic Change

Reason: Improve power domain handling for signal FPGA_IO.

...

Reason: Use standard fiducials.

Impact: None.

#17 Removed

...

track-it traceability pad S/N.

Type: Schematic Change

Reason: EOL of Component.

...

Type: PCB Change

Reason: Improve signal monitoringtesting.

Impact: None.

#19 Added serial number box print on bottom overlay.

...

Production Shipment Schedule

From July 20252024, after old stock is gone. If the new revision is not suitable for your application and still the former revision of the board is needed, please contact us.
