The NAND Controller firmware contains a list of supported standard NAND flash media devices. Upon initial Power-on, the
In the event that the NAND flash media device ID is not recognized by the NAND Controller, the user has an option of adding
Data Sheet
MANUFACTURING SUPPORT
controller scans all connected flash media devices and reads their device ID. If the device ID matches the listed flash media
devices in the NAND Controller, the controller performs drive recognition based on the algorithm provided by the flash media
suppliers, including setting up the bad block table, executing 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 13.
Please contact Greenliant for the most current list of supported NAND Flash media devices.
this device to the controller device table through the manufacturing interface provided by Greenliant. Please contact Green-
liant for the NAND Controller manufacturing interface software. If the drive initialization fails, and a visual inspection is unable
to determine the problem, the GLS55VD020 NAND Controller 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 cus-
tomization of user definable options.
ATA/IDE Interface
The NAND Controller interface can be used for manufacturing support. Greenliant provides an example of a DOS-based
solution (an executable routine available from Greenliant) for manufacturing debug and rework.
Serial Communication Interface (SCI)
For additional manufacturing flexibility, the SCI bus can be used to report manufacturing errors. The SCI consists of 3 active
signals: SCID
Security Features
The GLS55VD020 NAND Controller offers the standard ATA Security Mode Feature Set, a password system that restricts
the access of user data stored in the device. For additional data security features, please contact Greenliant.
