The ATA Flash Disk Controller recognizes the control, address, and data signals on the ATA/IDE bus and translates them into memory accesses to the standard NAND-type flash media. The SST55LD019A/B/C device supports Single Level Cell (SLC) flash media. This technology suits solid state mass storage applications offering new, expanded functionality while enabling smaller, lighter designs with lower power consumption. The ATA/IDE interface is widely used in such products as portable and desktop computers, digital cameras, music players, handheld data collection scanners, PDAs, handy terminals, personal communicators, audio recorders, moni- toring devices, and set-top boxes. SST’s ATA Flash Disk Controller supports standard ATA/IDE protocol with up to PIO Mode-4 and Multi-word DMA Mode-2 interface. Utilizing SST’s proprietary SuperFlash memory technol- ogy, the ATA Flash Disk Controller is factory pre-pro- grammed with an embedded flash file system which, upon initial Power-on, recognizes the attached flash media devices, sets up a bad block table, executes all necessary handshaking routines for flash media support, and, finally, performs the low-level format. This process typically takes about 3 sec + 0.5 sec/GByte of drive capacity, allowing a 2 GByte flash drive to be fully initialized in about 4 sec- onds. This technology enables a very fast, completely seamless integration of flash drives into an embedded design. For added manufacturing flexibility, system debug, re-initializa- tion, and user customization can be accomplished either through the ATA/IDE interface, for ATA Disk Module or flash drive products, or through the Serial Communication Interface (SCI), for fully embedded ATA Flash Disk Con- ATA Flash Disk Controller SST55LD019A / SST55LD019B / SST55LD019C SST55LD019A/B/CHigh-Performance ATA Flash Disk Controller |
