Functional Description

JTAG

Used only for Firmware Update. Zynq has dedicated JTAG connection.

Power

Power enables (EN_1V, EN_1V8, EN_3V3, EN_1V2_MGT, EN_1V0_MGT) are all enabled (constant 1).

Power goods (PG_1V, PG_1V5, PG_1V8, PG_3V3, PG_1V2_MGT, PG_1V0_MGT) are uses for System Reset and LED Monitoring.

Boot Mode

Is set fix to QSPI (MIO(5:3) = 100)

Reset

PS_SRST is main power failed or user reset (RESIN).

ETH1_RESET is main power failed and ETH1_RESET33 and DONE.

OTG_RST is main power failed and ETH1_OTG_RST33 and DONE.

MMC_RST is main power or mgt power failed.

UART

 MIO8 is connected to CONFIGX.

BOOTMODE is connected to MIO9.

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.
