SST55LC100M
CompactFlash Card Controller
Supports MLC and High Density SLC Flash Media Only
The SST55LC100M CompactFlash Card Controller is the heart of a high-performance, flash media-based Compact-Flash card solution. The SST55LC100M recognizes the control, address, and data signals on the CompactFlash bus and translates them into memory accesses to the standard NAND-type flash media. The SST55LC100M device supports Multi-Level Cell (MLC) and high density Single Level Cell (SLC) Flash media only. This technology suits solid state mass storage applications offering new, expanded functionality while enabling smaller, lighter designs with lower power consumption.
The CompactFlash interface is widely used in products such as portable and desktop computers, digital cameras, music players, handheld data collection scanners, PDAs, handy terminals, personal communicators, audio recorders, monitoring devices, and set-top boxes. The SST55LC100M supports CFA Specification Revision 2.0 commands standard with up to PIO Mode-4.
Utilizing SST’s proprietary SuperFlash embedded memory technology, the CompactFlash card controller is pre-programmed with an embedded flash file system which, upon initial power-up, recognizes the flash media devices, sets up a bad block table, executes all the necessary handshaking routines for flash media support, and, finally, performs the low-level format.
This technology enables a very fast and completely seamless integration of flash drives into an embedded design. For added manufacturing flexibility, system debug, re-initialization, and user customization can be accomplished through the CompactFlash interface.
The SST55LC100M CompactFlash Card Controller offers sustained read and write performance up to 10.0 MB/sec. The device can support up to 8 flash media devices directly for up to 8 GByte of maximum CompactFlash Card capacity.
The CompactFlash card controller comes packaged in an industry standard 100-lead TQFP package or 84-ball BGA package for easy integration into an SMT manufacturing process.
