NAND-type Flash Memory Controller IC GBDriver XR
Memory Bus Interface Type
Conformity to RoHS Directive
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.
