They combines an integrated ATA Controller and a 128/256/512 MB NAND Flash die in a multi-chip package. These products are well suited for solid state mass storage applications offering new and expanded functionality while enabling cost effective designs.
ATA-based solid state mass storage technology is widely used in such products as portable and desktop computers, digital cameras, music players, handheld data collection scanners, cellular phones, PCS phones, PDAs, handy terminals, personal communicators,advanced two-way pagers, audio recorders, monitoring devices, and set-top boxes. SST NANDrive IC supports standard ATA/IDE protocol with up to PIO Mode-4 and Multi-word DMA Mode-2 interface.
The NANDrive is a single SST85LD0128, solid state drive that is designed for embedded systems using standard ATA/IDE protocol. It has built in microcontroller and file management firmware that communicates with ATA standard interfaces; therefore, the device does not require additional or proprietary software such as Flash File System (FFS) and Memory Technology Driver (MTD) software.
The SST85LD0128 provides complete IDE Hard Disk Drive functionality and compatibility in the industry's smallest 12mmx18mm BGA package for easy, space saving, and cost effective mounting to a system motherboard. It is a perfect solution for portable, consumer and OEM, electronic products requiring smaller and more reliable data storage.
The SST85LD0128/0256/0512 NANDrive devices offer added security protection for confidential information stored in the flash media. They allow up to four protection zones which can be set by the user to be Read-only or Hidden (Read-disabled). The SST85LD0128/0256/0512 accesses data within the protected zones through a passwordprotected command. The NANDrive also provides a WP_PD# pin to protect critical information stored in the flash media from unauthorized overwrites.
The NANDrive devices come pre-programmed with a 10-byte unique serial ID. For even greater system security, the user has the option of programming an additional 10 Bytes of ID space to create a unique, 20-byte ID. Additionally, the capacity of the NANDrive products can be easily expanded by connecting discrete NAND flash components through the external Media bus.
