1. 1 1 NAND type Flash Memory Controller IC GBDriver XR contormity to RoHs Directive Memory Bus Interface Type For Small Embedded Systems without an ATA IDE interface NAND type Flash Memory has occupied significant place in embedded systems In many cases the system size is small and an ATA interface is not used The TDK GBDriver XR bridges those host interfaces without an ATA bus to NAND type Flash Memory The built in engine is the TDK GBDriver RAS controller The GBDriver RAS is the recipient of numerous design wins and strong interest from our customer base GBDriver XR interfaces with a common memory bus such as SRAM bus enabling CPU to connect with and thus control NAND type Flash Memory directly GBDriver XR makes it possible to build storage systems even if they do not have hard disk interface such as ATA IDE The XR is packaged in an ultra small ultra thin VFBGA This simplifies insertion into portable devices mobile terminals and small IT home appliances FEATURES SHAPES AND DIMENSIONS e World s first NAND type Flash Memory controller interfacing with VFBGA100pin Single Chip common memory bus such as a one chip LSI solution i Cerne Realizes 6MB s burst writes when directly connected with the marking 12345678910 oO O0W0O0WOO0O00ND DY jo olOO0O00000 0 0 a Q system bus Controls NAND type Flash Memory up to 4GB Confirmed compatibility with Flash Memories of several makers High reliability in Write and Read2. by TDK original systematic control over NAND type Flash Memory e ATA compatible register interface suitable for use with the FAT file system only low level driver required e Available in 8mmHVFBGA100pin package e Supports auto recovery function option e Conforms to the RoHS directives Please contact us to confirm the Flash Memory compatibility At corner marking 6 75 oooo0oo0oo0o0o0j N AcCTOTMMVOD gt S O0O00000000 IN O0O0000000 0 O000000 0 H O0O0000000 0 f O0O0O000000 0 jw OoO0000000 0 0 0 0 0 0 0 0 AcCTOaTTMVODW gt 100 0 25 to 0 35 MAIN APPLICATIONS e Flash memory modules e Silicon storage e Boot devices for embedded systems 0 18 to 0 28 Land amp lead Solder resist Opening size Dimensions in mm APPLICATIONN EXAMPLES e For NOR Flash HDD replacement applications SPECIFICATIONS 120ns Burst cycle e For user data storage applications home information Timing specifications mest 180ns Single cycle appliances STBs PDAs mobile phones etc Flash I F 90ns e For booting embedded systems of WindowsXP Embedded base Host I F 2 7 to 3 6V or Linux base Power specifications Core 2 7 to 3 6V Flash I F 2 7 to 3 6V System clock ee y External clock support paaugs SO p g Storage 55 to 125 C Power consumption Reading 41mA 3 0V ref Writing 40mA 3 0V e GBDriver is a registered trad
