Overview of HSPSIG63EFR Series DDR2 SDRAM by SK hynix
The HSPSIG63EFR Series datasheet presents information pertinent to SK hynix’s 1Gb DDR2 SDRAM. This series encompasses several model numbers, including HSPSIG63EFR-XXC, HSPSIG63EFR-xxl, HSPS1G63EFR-XxL, and HSPSIG63EFR-XxJ, which vary in specification and performance. A critical notice to the reader indicates that the document serves as a general product description which can undergo changes without notice, and SK hynix shoulders no responsibility for the usage of the described circuits, nor does it grant patent licenses.
Furthermore, the datasheet includes a revision history reflecting updates that have taken place over time. The first recorded version, 1.0, was released in June 2009, featuring changes to the power supply and operational characteristics for the -P & -Q product classes (identified as Page16 IDDO, IDD1, IDDAR, and IDDAW). This was documented in July of the same year with Revision 1.1, where these values were removed from the datasheet. Subsequent versions, such as 1.2 and the latest 1.3, involve the deletion of the xxP and xxQ products and the introduction of a revised SK hynix logo. These changes denote an active development and product lifecycle management by SK hynix.
The datasheet records changes to the electrical parameters of the DDR2-667 and DDR2-800 modules. Key parameters, including TDDO, IDDI, IDDAR, and IDD4W, which refer to different current measurements in milliamps (mA), are also given before and after values. With these updates, the DDR2-667 modules show increased tolerances in power consumption, and DDR2-800 slightly higher subsequently. These details are critical for designers and engineers to consider during system development and integration, impacting system performance and thermal management.
