  • 1. (1/1) NAND-Type Flash Memory Controller GBDriver RA6 Conformity to RoHS Directive PCMCIA, ATA Interface Type For Embedded Systems/ Silicon Disk/ CompactFlash® NAND-type Flash Memory has been changing its memory cell structure, cell size, and functions, and increases in its capacity and reductions to its cost have been undergoing rapid promotion through downsizing. However, if the flash memory generation change accelerates without keeping cross-generational compatibility, procurement of NAND-type Flash Memory may become difficult and a larger risk of restricting system introductions and system designs may arise. The TDK GBDriver RA6 eliminates these risks by controlling the latest flash memory (TwoPlane-write Flash Memory) while maintaining support for existing NAND-type Flash Memory. Aside from this, the GBDriver RA6 supports UltraDMA Mode2 with a maximum transfer speed of 33.3MB/s, in order to control the latest flash memory with the industry’s highest level of speed. Moreover, the architecture of wear levelling has been renewed. Even for disproportionate writing to memory, the GBDriver RA6 controls write levelling in order to prevent writing from being concentrated on any particular part of the memory. Along with the newly equipped system-strengthening functions (the smart command support and the function of setting all sector numbers [clipping function]), this pro- longs the life of NAND-type Flash Memory and increases reliability in using NAND-type Flash Memory as an HDD substitute. FEATURES SHAPES AND DIMENSIONS • Supports UltraDMA Mode2. Realizes 20MB/s(equivalent to 138 TQFP128pin Single Chip times speed) in burst writing and 23MB/s(equivalent to 150 96 65 times speed)∗1 in reading by the host. • Controls NAND-type Flash Memory up to 8GB. Confirmed 97 64 compatibility with Flash Memories of several manufacturers.∗2 • The TDK flash control technology utilizes fault tolerant architecture to protect against power failure errors. • Command and power management specifications conform to the CompactFlashTM Specification Version 3.0. 14.0±0.2 16.0±0.2 • Supports the smart command. Equipped with the function to read the number of used blocks, unused blocks, and fault blocks, and the memory lifespan can be estimated. • Custom settings for the CIS data and the vender-unique area of "Identify Device" command are supported. • Equipped with the function to set all sector numbers (clipping No.1 terminal corner marking function). The number of physical blocks can be set to be smaller, in order 128 33 to increase the number of times that rewriting to the flash memory is possible. 1 0.18±0.05 0.4bsc. 32 • Supports a protect function conforming to the ATA standard. In 14.0±0.2 addition to the existing TDK unique Write Protect/Read Protect 16.0±0.2 functions, the user can set or disable the password.
