Functional Description
JTAG
JTAG signals routed directly through the CPLD to FPGA. Access between CPLD and FPGA can be multiplexed via JTAGEN (logical one for CPLD, logical zero for FPGA) on JM1-89.
Boot Mode
Boot Modes can be selected via B2B Pin Mode. Trenz Electronic provides currently 4 Firmware variants, one for SD/JTAG, one for JTAG/QSPI, one for SD/QSPI and SD/QSPI/JTAG usage.
Mode | JTAG/QSPI-Variant | SD/JTAG-Variant | SD/QSPI (default Firmware) | SD/QSPI/JTAG |
---|---|---|---|---|
low | JTAG | Boot from SD | Boot from SD | JTAG Mode, if NOSEQ* is high otherwise boot from SD |
high | Boot from Flash | JTAG | Boot from Flash | JTAG Mode, if NOSEQ* is high otherwise boot from Flash |
For other UltraScale+ Boot Modes options custom firmware is needed, see also Table 11.1 Boot Modes from Xilinx UG1085.
A special FSBL is provided on 2017.4 or newer reference designs to write boot image to QSPI with Xilinx tools (Vivado or SDK) on Boot Mode unequal JTAG .
NOSEQ*: Please check the carrier board documentation, before using the SD/QSPI/JTAG firmware variant on TE0820. In the most cases special carrier CPLD firmware is needed.
Power
PGOOD is EN1 and not ER_OUT. There is no additional power management controlled by CPLD.
Internal pullup is used for detection, ER_OUT IO powered by 1.8V. To detect power status, also B2B 1.8V or 3.3V output is usable.

The products we supply to you are solely non-chemical products (goods). Moreover and under normal and reasonably foreseeable circumstances of application, the goods supplied to you shall not release any substance. For that, Trenz Electronic is obliged to neither register nor to provide safety data sheet. According to present knowledge and to best of our knowledge, no SVHC (Substances of Very High Concern) on the Candidate List are contained in our products. Furthermore, we will immediately and unsolicited inform our customers in compliance with REACH - Article 33 if any substance present in our goods (above a concentration of 0,1 % weight by weight) will be classified as SVHC by the European Chemicals Agency (ECHA).
RoHS
Trenz Electronic GmbH herewith declares that all its products are developed, manufactured and distributed RoHS compliant.
WEEE
Information for users within the European Union in accordance with Directive 2002/96/EC of the European Parliament and of the Council of 27 January 2003 on waste electrical and electronic equipment (WEEE).
Users of electrical and electronic equipment in private households are required not to dispose of waste electrical and electronic equipment as unsorted municipal waste and to collect such waste electrical and electronic equipment separately. By the 13 August 2005, Member States shall have ensured that systems are set up allowing final holders and distributors to return waste electrical and electronic equipment at least free of charge. Member States shall ensure the availability and accessibility of the necessary collection facilities. Separate collection is the precondition to ensure specific treatment and recycling of waste electrical and electronic equipment and is necessary to achieve the chosen level of protection of human health and the environment in the European Union. Consumers have to actively contribute to the success of such collection and the return of waste electrical and electronic equipment. Presence of hazardous substances in electrical and electronic equipment results in potential effects on the environment and human health. The symbol consisting of the crossed-out wheeled bin indicates separate collection for waste electrical and electronic equipment.
Trenz Electronic is registered under WEEE-Reg.-Nr. DE97922676.
