TDK Memory Bus Interface Type User manual

Brand: TDK

Model: Memory Bus Interface Type

Type: User manual

TDK Memory Bus Interface Type is a compact and versatile device that can be used to connect NAND-type Flash Memory to a system bus. It is ideal for small embedded systems that do not have an ATA/IDE interface.

The device has a built-in GBDriver RA3 controller, which supports burst writes of up to 6MB/s. It can control NAND-type Flash Memory up to 4GB, and is compatible with Flash Memories from several makers.

The device is also highly reliable, thanks to TDK's original systematic control over NAND-type Flash Memory. It has an ATA compatible register interface, making it suitable for use with the FAT file system.

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.
