Revision: 1.40 www.swissbit.com industrial@swissbit.com unitedCONTRAST_ExBP_data_sheet_Rev140 Page 12 of 18 ## **14 RoHS and WEEE update from Swissbit** Dear Valued Customer, We at Swissbit place great value on the environment and thus pay close attention to the diverse aspects of manufacturing environmentally and health friendly products. The European Parliament and the Council of the European Union have published two Directives defining a European standard for environmental protection. This states that CompactFlash Cards must comply with both Directives in order for them to be sold on the European market: - RoHS – Restriction of Hazardous Substances - WEEE – Waste Electrical and Electronic Equipment Swissbit would like to take this opportunity to inform our customers about the measures we have implemented to adapt all our products to the European norms. ## What is the WEEE Directive (2012/19/EC)? The Directive covers the following points: - Prevention of WEEE - Recovery, recycling and other measures leading to a minimization of wastage of electronic and electrical equipment - Improvement in the quality of environmental performance of all operators involved in the EEE life cycle, as well as measures to incorporate those involved at the EEE waste disposal points ## What are the key elements? The WEEE Directive covers the following responsibilities on the part of producers: Producers must draft a disposal or recovery scheme to dispose of EEE correctly. Producers must be registered as producers in the country in which they distribute the goods. They must also supply and publish information about the EEE categories. Producers are obliged to finance the collection, treatment and disposal of WEEE. ## Inclusion of WEEE logos on devices In reference to the Directive, the WEEE logo must be printed directly on all devices that have sufficient space. «In exceptional cases where this is necessary because of the size of the product, the symbol of the WEEE Directive shall be printed on the packaging, on the instructions of use and on the warranty» (WEEE Directive 2012/19/EC) ## When does the WEEE Directive take effect? The Directive came into effect internationally on July 04, 2012. ## What is RoHS (2011/65/EU)? The goals of the Directive are to: - Place less of a burden on human health and to protect the environment by restricting the use of hazardous substances in new electrical and electronic devices - To support the WEEE Directive (see above) RoHS enforces the restriction of the following 6 hazardous substances in electronic and electrical devices: - Lead (Pb) – no more than 0.1% by weight in homogeneous materials - Mercury (Hg) – no more than 0.1% by weight in homogeneous materials - Cadmium (Cd) – no more than 0.01% by weight in homogeneous materials - Chromium (Cr6+) – no more than 0.1% by weight in homogeneous materials - PBB, PBDE – no more than 0.1% by weight in homogeneous materials Swissbit reserves the right to change products or specifications without notice. www.swissbit.com Swissbit AG Industriestrasse 4 CH-9552 Bronschhofen Switzerland Revision: 1.40 unitedCONTRAST_ExBP_data_sheet_Rev140 Page 13 of 18 industrial@swissbit.com Swissbit is obliged to minimize the hazardous substances in the products. According to part of the Directive, manufacturers are obliged to make a self-declaration for all devices with RoHS. Swissbit carried out intensive tests to comply with the self-declaration. We have also already taken steps to have the analyses of the individual components guaranteed by third-party companies. Swissbit carried out the following steps during the year with the goal of offering our customers products that are fully compliant with the RoHS Directive. - Preparing all far-reaching directives, logistical enhancements and alternatives regarding the full understanding and introduction of the RoHS Directive’s standards - Checking the components and raw materials: - Replacing non-RoHS-compliant components and raw materials in the supply chain - `o` Cooperating closely with suppliers regarding the certification of all components and raw materials used by Swissbit - - Modifying the manufacturing processes and procedures - Successfully adapting and optimizing the new management-free integration process in the supply chain - Updating existing production procedures and introducing the new procedures to support the integration process and the sorting of materials - Carrying out the quality process `o` Performing detailed function and safety tests to ensure the continuous high quality of the Swissbit product line ## When does the RoHS Directive take effect? As of June 08, 2011 only new electrical and electronic devices with approved quantities of RoHS will be put on the market. When will Swissbit be offering RoHS-approved products? Swissbit’s RoHS-approved products are available now. Please contact your Swissbit contact person to find out more about exchanging your existing products for RoHS-compliant devices. For your attention We understand that packaging and accessories are not EEE material and are therefore not subject to the WEEE or RoHS Directives.

This means that the user accessible data range (LBA area) is evenly divided into multiple zones, which are all managed separately for both, wear leveling (dynamic and static) and for spare & bad block management. ## USB HOST INTERFACE ## USB FLASH DRIVE |FIRST SECTOR(LBA 0)|||LAST SECTOR| |---|---|---|---| |ZONE1 (MU1)|ZONE2 (MU2)|ZONE3 (MU3)|ZONE4 (MU4)| ## *MU=Management Unit The number of zones is depending on the device capacity and can be read out using the Swissbit Life Time Monitoring tool. The tool will show the number of available spare blocks per management unit (zone). The devices need a minimum number of 2 spare blocks per unit to work with. If the first unit reaches this value, the device will be write-protected by the firmware. To get optimal life time, write accesses must be evenly distributed over all zones. This can, for example, be achieved by using multiple partitions and by then distributing the data between the partitions. ## _**15.1 Device Removal**_ **&** _**Power Failure**_ User data can be lost or corrupted if power is interrupted while the UFD is writing data. To avoid data loss, it is necessary to avoid power interruption while the device is busy. This can be made sure by always using the host (e.g. Windows) shutdown mechanisms or by detaching the device in the operating system before unplugging it. Swissbit also offers an Application Note “Design-In Guide” that describes techniques to reduce data loss on power failure, if power failure absolutely can’t be avoided. ## _**15.2 Lifetime end handling**_ If the flash reaches its end of life, the number of bad blocks will increase (bad flash blocks will be replaced with spare blocks). There exist different side effects with negative data influence by degraded flash cells. Sometimes bit errors can occur because of effects that are not immediately detected by the flash, e.g. effects like program disturb or read disturb, which means that the bad block recognition does not always prevent data loss. When the number of bit errors in a sector exceeds the ECC correcting capabilities, invalid (uncorrected) data can be reported back to the host. Because of these effects it is strongly recommended to replace devices that are nearing their end of life. One good indicator would be the current spare blocks per unit should not be reducing below 5. It is in the responsibility of the system integrator to account for the flash usage per zone. Swissbit offers support for calculating expected life time if the exact use case is provided (e.g. by providing low level [USB interface] write statistics). For notes on reducing flash stress, Swissbit offers an Application Note called “Design-In Guide”. Please contact your sales channel for more information or send a mail to sales@swissbit.com.
