5.0 MANUFACTURING SUPPORT
The CompactFlash card controller firmware contains a list of supported standard NAND flash media devices. Upon
initial Power-on, the controller scans all connected flash media devices and reads their device ID. If the device ID
matches the listed flash media devices in the CompactFlash card controller, the controller performs drive recogni-
tion based on the algorithm provided by the flash media suppliers, including setting up the bad block table, execut-
ing all the necessary handshaking routines for flash media support, and, finally, performing the low-level format. For
Power-up timing specifications, please refer to Table 10-2.
Please contact SST for the most current list of supported NAND Flash media devices.
In the event that the NAND flash media device ID is not recognized by the CompactFlash card controller, the user
has an option of adding this device to the controller device table through the manufacturing interface provided by
SST. Please contact SST for the CompactFlash card controller manufacturing interface software. If the drive initial-
ization fails, and a visual inspection is unable to determine the problem, the SST55LC100 CompactFlash card con-
troller provides a comprehensive interface for manufacturing flow debug. This interface not only allows debug of the
failure and manual reset of the initialization process, but also allows customization of user definable options.
5.1 CF Interface
The CompactFlash interface can be used for manufacturing support. SST provides an example of a DOS-based
solution (an executable routine downloadable from SST’s web site) for manufacturing debug and rework.
5.2 Serial Communication Interface (SCI)
For additional manufacturing flexibility, the SCI bus can be used for manufacturing error reporting. The SCI consists
of 3 active signals: SCIDOUT, SCIDIN, and SCICLK.
6.0 EXTERNAL CLOCK INTERFACE
The external clock interface allows CompactFlash card controller operation from an external clock source gener-
ated by an RC circuit. Do not use a free running clock as input to the EXTCLKIN pin; an RC circuit must be used.
Contact SST for reference circuit and recommended external clock settings.
While the controller has an internal clock source, the external clock source allows slowing of the system clock oper-
ation to limit the peak current and overcome additional bus loading.
The external clock interface consists of three signals: INTCLKEN, EXTCLKIN, and EXTCLKOUT. The INTCLKEN
pin selects between external and internal clock sources for the CompactFlash card controller. If this pin is pulled
high before device Power-on, then the internal clock source is selected; otherwise, the external clock source is
selected. The EXTCLKIN and EXTCLKOUT signals are the input and output clock signals, respectively.
