PRODUCT DESCRIPTION
The SST55LC100 CompactFlash Card Controller is the
heart of a high-performance, flash media-based Compact-
Flash card solution. The SST55LC100 recognizes the con-
trol, address, and data signals on the CompactFlash bus
and translates them into memory accesses to the standard
NAND-type flash media. The SST55LC100 device sup-
ports the Single Level Cell (SLC) media only. This technol-
ogy suits solid state mass storage applications offering
new, expanded functionality while enabling smaller, lighter
designs with lower power consumption.
up a bad block table, executes all the necessary handshak-
ing routines for flash media support, and, finally, performs
the low-level format.
This technology enables a very fast, completely seam-
less integration of flash drives into an embedded design.
For added manufacturing flexibility, system debug, re-ini-
tialization, and user customization can be accomplished
through the CompactFlash interface.
The SST55LC100 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 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 record-
ers, monitoring devices, and set-top boxes. The
SST55LC100 supports CFA Specification Revision 2.0
commands standard with up to PIO Mode-4.
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.
Utilizing SST’s proprietary SuperFlash embedded memory
technology, the CompactFlash card controller is pre-pro-
grammed with an embedded flash file system which, upon
initial power-up, recognizes the flash media devices, sets
