  • 1. (1/1) NAND Flash Memory Controller GBDriver SA Conformity to RoHS Directive PCMCIA, ATA Interface Type For Systems That Use SmartMediaTM By compressing the control information needed for controlling the blocks in NAND flash memory chips and by adapting to the table management technology based on virtual memory systems, we have succeeded in developing a single chip that supports the next generation of flash memory chips that have address spaces of 16Gb per chip. This is a state-of-the-art NAND flash controller that supports next- generation memory cards based on NAND flash memory, Smart- MediaTM PC card adapters and built-in device systems that use these memory devices. FEATURES SHAPES AND DIMENSIONS • Capable of controlling up to 16Gb flash memory chips. 16.0±0.2SQ • Command and power management specifications conform to 14.0±0.1SQ Compact Flash rev. 1.4. 75 51 • CIS information and the vendor unique area in the Identity Drive 76 50 command are customizable (Please note that SmartMediaTM specifies the CIS information). • Capable of controlling SmartMediaTM with capacities of 2 to 256MB. Detail of A • Supports 3V and 5V flash memory chips of 2MB to 2GB.. 0˚ to 10˚ 100 26 • Can be used for a wide range of systems because it is based on Index a highly compatible host interface technology that we have Pin No. 1 25 A 0.5typ. 0.22 0.5typ. continued to develop over the years for the GB Driver series. 1.2max. 1.0±0.2 • For both its flash memory write control and its bad block Dimensions in mm management scheme, this controller has been accepted in the Compliance Test by the SSFDC Forum which governs SmartMediaTM (Please call for details). SPECIFICATIONS Host interface 250ns[BUS cycle] MAIN APPLICATIONS Flash interface 100ns Host I/F 3.0 to 3.6V or 4.5 to 5.5V • SmartMediaTM and next generation memory cards Power Core 3.0 to 3.6V • Silicon disk devices specifications Flash I/F 3.0 to 3.6V or 4.5 to 5.5V System clock 20MHz APPLICATION EXAMPLES Temperature Operation –40 to +85°C range Storage –55 to +125°C • Systems can be designed for a wide range of applications and purposes because the controller’s characteristics, including the 3.3VCIS output mode, can be configured on an external PERFORMANCE (REFERENCE) [When accessing the host interface at terminal. Write to 250ns (This is affected by the flash About 1.3MB/s memory’s program and erase times)] [When accessing the host interface at Read from About 3.5MB/s 250ns] • GBDriver is a registered trademark of TDK Corp. • SmartMediaTM is a registered trademark of Toshiba Corp. • Other company and product names included in this document are the trade- marks or the registered trademarks of the respective companies. • Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications. • All specifications are subject to change without notice. 001-03 / 20070226 / ew_001.fm
