NAND-type Flash Memory Controller IC GBDriver XR
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 RA3 controller. The GBDriver RA3 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
• World’s first NAND-type Flash Memory controller interfacing with
common memory bus, such as a one chip LSI solution.
• Realizes 6MB/s burst writes when directly connected with the
system bus.
• Controls NAND-type Flash Memory up to 4GB. Confirmed
compatibility with Flash Memories of several makers.∗
• High reliability in Write and Read by TDK original systematic
control over NAND-type Flash Memory.
• ATA compatible register interface, suitable for use with the FAT
file system, only low level driver required.
• Available in 8mmVFBGA100pin package.
• Supports auto recovery function (option)
• Conforms to the RoHS directives.
∗Please contact us to confirm the Flash Memory compatibility.
