Functional Description
JTAG
JTAGENB set CPLD into the Chain for Firmware update. In normal mode every FMC JTAG will be set into the chain, when his FMCx_PRSNT is detected.
Power
ENN_12V and EN_VCCINT are enabled. All other powers will be enabled if, PG_12V and PG_FPD are valid.
Reset
PROG_B always one. MR and SC_IO0 controlled by USR_BUT2 (S2) and power management.
Bootmode
SD Boot, when SC_SW1 is one else SQPI Boot.

FANs
6 FMC FANs controlled by corresponding FMCx_PRSNT signals to enable FANs only for active FMC slots.
RGPIO
RGPIO Master is a 32Bit Remote GPIO Interface to talk with FPGA over 3 lanes.

REACH, RoHS and WEEE
REACH
Trenz Electronic is a manufacturer and a distributor of electronic products. It is therefore a so called downstream user in the sense of REACH. 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.
