The NAND Con- puters, portable media player, music players, handheld troller recognizes the control, address, and data signals on data collection scanners, PDAs, handy terminals, personal the ATA/IDE bus and translates them into memory communicators, audio recorders, monitoring devices, and accesses for standard NAND-type flash media. Utilizing set-top boxes. both Single-Level Cell (SLC) and Multi-Level Cell The NAND Controller uses SuperFlash memory technol- (MLC) flash media, this technology supports solid state ogy and is factory pre-programmed with an embedded mass storage applications by offering new, expanded flash file system. Upon initial power-on, the GLS55VD020 functionality while enabling smaller, lighter designs with recognizes attached flash media devices, sets up a bad lower power consumption. block table, executes all necessary handshaking routines The NAND Controller supports standard ATA/IDE protocol for flash media support, and, finally, performs the low-level with up to PIO Mode-6, Multi-word DMA Mode-4, and format. This process typically takes about 3 second plus Ultra DMA Mode-4 interface. The ATA/IDE interface is 0.5 seconds per gigabyte of drive capacity, allowing a 4 2010 Greenliant Systems, Ltd. www.greenliant.com S71355-04-000 05/10NAND Controller GLS55VD020 Data Sheet GByte flash drive to be fully initialized in about 5 seconds. cal information stored in the flash media from unauthorized For added manufacturing flexibility, system debug, re-ini- overwrites. tialization, and user customization can be accomplished The NAND Controller comes pre-programmed with a 10- through the ATA/IDE interface. byte unique serial ID.
