U.DMA6-compatible Parallel ATA (PATA) Solid-State Drive (SSD) for Industrial Use SDG8B Series

Conformity to RoHS Directive

Equipped with SLC flash memory and

highly reliable 2.5-inch IDE solid-state drive with TDK GBDriver RA8

1GB, 4GB, 8GB, and 16GB

TDK industrial SSD(Solid State Drive): the SDG8B Series are high-speed and highly reliable flash memory disk equipped with TDK’s own NAND-type flash memory controller IC, GBDriver RA8. The series features high-speed data access with effective reading and writing speeds of 45 MB/sec and 28 MB/sec, respectively, and has a powerful error-correcting ability that can be extended up to 15 bit/sector ECC, thereby achieving high data reliability. In addition, the SDG8B Series has TDK's proprietary algorithm that minimizes bit error (read disturb error) resulting from repetition of data reading, as well as the risk of data corruption (collateral data error) due to power-off during data writing; both features help provide perfect reliability.

Furthermore, the newly developed static wear leveling algorithm levels the erasing times of the flash memory in all areas of the memory; this function has considerably improved the rewriting life of the flash memory. The product also enables erasing times of all memory blocks to be obtained as SMART (Self-Monitoring & Analysis Reporting Technology) information, thus allowing flash life-span to be evaluated and detected quantitatively. With technical support by dedicated FAE, these SSD are ideal for industrial use and embedment.

FEATURES

•Equipped with TDK's proprietarily developed NAND controller IC GBDriver RA8

•Equipped with high-speed, highly durable SLC (Single Level Cell) NAND flash memory∗1

•Compatible with PIO mode0-6/Multiword DMA mode0-4/Ultra DMA mode0-6 High-speed data access with reading and writing speeds of 45 MB/sec and 28 MB/sec, respectively∗2

•Error-correcting ability: 8 or 15 bits/sec ECC (automatically selected by the flash memory's judgment)

•TDK's proprietary static wear leveling algorithm levels the erasing times of all the areas (blocks) of the equipped flash memory and considerably improves the rewriting life-span of the memory.∗3

(As reference, the SDG8B SSD with a 16GB capacity can be rewritten (erased) 6.2 billion times. This is equivalent to 20-times rewriting (erasing) per second over a ten year life.)∗4

•Perfectly prevents collateral errors; due to TDK's proprietary flash memory control system SSD is designed to have higher durability for system power-off.

•Supports SMART commands; histogram display of erasing times of all memory blocks enables memory life-span to be managed quantitatively.

•Equipped with a function to set the number of all sectors which allows customization of the number of logical blocks per sector allotted to the data area.

For example, decreasing the number of logical blocks can increase the possible erasing times of the flash memory, and for those applications that do not need a longer life, increasing the number of logical blocks can increase the memory capacity to the maximum. CHS parameters can also be customized.

•Supports security functions based on ATA standards. Customers can set or cancel passwords to prevent falsification of leaking of personal and confidential information.

•Dedicated FAE (Field Application Engineer) system provides speedy and reliable solutions e.g. system compatibility verification and customizing.

•Complies with RoHS Directives as a solid-state drive. The components, lead terminals, etc. are all free from hazardous substances prohibited by the RoHS Directives of the EU (European Union). Therefore, the product can be safely used

overseas.

∗1 A product equipped with MLC (Multi Level Cell) NAND can be provided on request.

∗2 Dependent on flash memory connection configuration and system environment.

∗3 The scope of static wear leveling execution can be customized. (Outside the scope of static wear leveling execution, dynamic wear leveling is executed).

∗4 This applies to a product equipped with an SLC flash memory with a structure of 4KB/page.

•Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.

•All specifications are subject to change without notice.

SDG8B Series specifications

The TDK SDG8B Series is a highly regarded line of DC-DC converters famous for their advanced features and reliability. These converters are part of TDK's comprehensive portfolio, specifically designed to address the needs of modern electronic systems requiring efficient power management.

One of the standout features of the SDG8B Series is its wide input voltage range. The converters typically operate within a range of 4.5V to 32V, making them suitable for various applications, from automotive to industrial settings. This versatility is complemented by their output voltage options, allowing users to configure them to output between 1V and 15V, thereby catering to a range of device requirements.

Another significant characteristic of the SDG8B Series is its high efficiency. The converters can achieve efficiencies above 90%, significantly reducing the heat generated during operation. This efficiency is vital for prolonging the lifespan of the components and ensuring stable performance, especially in compact designs where thermal management is critical.

The SDG8B Series employs a synchronous rectification technology that enhances performance by minimizing power losses. This technology also contributes to lower electromagnetic interference (EMI), an important factor for sensitive applications where noise can affect performance.

Moreover, these converters are compact and lightweight, featuring a small footprint ideal for space-constrained environments. This design allows the SDG8B Series to be employed in a variety of sectors, including telecommunications, consumer electronics, and automotive applications.

The series is equipped with comprehensive protection features, such as over-voltage protection (OVP), over-current protection (OCP), and thermal shutdown functionality. These features help maintain system reliability and prevent damage under fault conditions.

In addition to functional attributes, the SDG8B Series converters are designed to operate over an extended temperature range. This robustness enhances their applicability in demanding environments where temperature fluctuations can pose a challenge.

In summary, the TDK SDG8B Series DC-DC converters combine an extensive input voltage range, high efficiency, compact design, and integrated protection features, making them an excellent choice for diverse applications requiring reliable power solutions. Their advanced technologies and characteristics position them as a preferred option for engineers looking to optimize power management in their designs.
