1 Solid State Drive(SSD) Development of the CFA9D Series CompactFlash (CF) Card and SDA9D Series SSD with PATA Support for Industrial Use Highly reliable CF card / PATA SSD with auto refresh function and built-in power supply backup circuitry Equipped with TDK-developed GBDriver RA9 NAND flash memory controller IC April 27, 2017 TDK Corporation announced the development and launch of the CFA9D Series of CompactFlash (CF) cards and the SDA9D Series of 2.5inch SSDs with parallel ATA (PATA) support, both of which are equipped with TDK-developed TDK GBDriver RA9 NAND Flash Memory Controller ICs. Sales are scheduled to commence in August The CFA9D Series and SDA9D Series incorporate high-speed, high-durability Single Level Cell (SLC) NAND flash memory, and come in a wide range of capacities from 128 MBytes to 32 GBytes (for the CFA9D Series) and 1 GByte to 64 GBytes (for the SDA9D Series) respectively. Both series are equipped with auto refresh functionality that refreshes data automatically at startup and periodically during use. Together with enhanced error correction capabilities (expandable up to 30-bit errors per 512 Bytes), this functionality offers a high level of data reliability. In addition to this, built-in power supply backup circuitry makes it easy to design systems for in the event of power interruption. These series also incorporate global static wear leveling capabilities, achieving long life span performance to take full advantage of NAND flash memory endurance. At the same time, the use of Self-Monitoring & Analysis Reporting Technology (SMART) data facilitates accurate drive lifespan management, enabling simple and easy maintenance such as in performing periodic replacements. The new products also have an enhanced range of data security features, including ATA security capabilities and TDK s own original security functionality, to provide robust protection from data falsification and leakage. These products will be on display at the Embedded Systems Expo (ESEC), which will take place at Tokyo Big Sight on May 10 12, Main applications Factory automation equipment such as semiconductor manufacturing equipment, NC machine tools, sequencers, programmable logic controllers, panel computers, and embedded CPU boards Railway and transport equipment such as automated ticket gates, automated ticket vending machines, commuter pass vending machines, train operation management systems, automated air ticket vending machines, and automated check-in systems TDK Corporation 1 / 5

Host Interface The CFA9D Series and SDA9D Series are compatible with PIO 0 6, Multiword DMA 0 4 and Ultra DMA 0 6 and support a read access speed of up to 50 MBytes per second, and a write access speed of up to 30 MBytes per second (depending on the flash connection configuration and the system environment). 2. Global Static Wear Leveling TDK s proprietary global static wear leveling algorithm counts the number of times each memory block is programmed (erased) and replaces all blocks uniformly. Static blocks such as for the OS are also periodically leveled, which drastically improves the lifespan of the installed drive. The range for static wear leveling can be freely set. (In this case, dynamic wear leveling control is carried out for other areas of memory not set as static wear leveling areas.) 3. Enhanced Power Interruption Tolerance The new CFA9D Series and SDA9D Series are equipped with TDK s GBDriver RA9 controller IC, which utilizes a proprietary algorithm and newly-added internal power supply backup circuitry to reduce the risk of collateral errors (such as the destruction of data other than those being written at the time of a power interruption) during the data writing process. These features make the new CF cards and PATA SSDs highly reliable and resistant against sudden power failure-related issues. 4. Error Correction and Recovery With a flash identification function selecting either 15-bit ECC per 512 Bytes or 30-bit ECC per 512 Bytes, the CFA9D Series and SDA9D Series boast error correction capabilities that are higher than the value required for NAND flash memories. The auto refresh function reads all data from all flash memory areas both at startup and periodically during use, and performs automatic error correction to prevent data losses caused by read disturb errors, data holding errors and other errors. The auto refresh function is performed in the background and causes little delay in the response to commands, even during the correction process. TDK Corporation 2 / 5

Other Functions (a) Function for setting the total number of sectors (clipping function) The number of logical sectors assigned to the data region may be increased or decreased in units of a single sector. (b) Security functions The CFA9D Series and SDA9D Series offer ATA standard security functionality that allows users to set and remove passwords, enabling independent authentication and protection of important data. (c) TDK s original security function (optional) This function restricts third parties from reading users data stored on NAND flash memories. (This function requires a separate non-disclosure agreement.) (d) Support for SMART commands With the use of SMART commands, it is possible to retrieve data on the number of overwrites (erases) in all memory blocks. This makes it easy to ascertain the state of flash memory, and enables accurate lifespan management. 6. Solution Support TDK has independently developed and marketed the GBDriver series of NAND type flash memory controllers since We provide technical support to customers in Japan and overseas backed up by advanced proprietary technologies, including dispatch of field application engineers (FAEs) and support for implementation of reliability monitoring functions, for which there is strong demand in the industrial equipment embedded flash storage market.
