Power-down Mode
ATA/IDE Host Interface
Serial Communication Interface
When the device is configured in the Power-down mode, if the WP#/PD# pin is asserted during a
command, the NANDrive stops the ongoing command and immediately enters power-down mode.
Afterwards, the device will not accept any other commands. Both a software or a hardware reset
will bring the device to normal operation with the WP#/PD# pin de-asserted.
NANDrive is self-initialized during the first power-up. As soon as the power is applied to the NAN-
Drive it reports busy for typically up to seven seconds while performing bad blocks search and low
level format. This initialization is a one time event.
During the first self-initialization, the NANDrive firmware scans all connected flash media devices
and reads their device ID. If the device ID matches the listed flash media devices, the NANDrive
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.
If the drive initialization fails, and a visual inspection is unable to determine the problem, Green-
liant 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 custom-
ization of user definable options.
The ATA/IDE host interface can be used for NANDrive manufacturing support. Greenliant provides
an example of a DOS- and Windows™-based solution (an executable routine) for manufacturing
debug and rework.
For additional manufacturing flexibility, the SCI bus can be used for manufacturing error reporting
and for accessing the status of the controller’s internal activities. The SCI consists of 3 active sig-
nals: SCID
design to aid in design validation.
NANDrive with advanced NAND management technology significantly extends the life of a product
with its extensive ECC and advanced wear-leveling.
For applications where data security is essential, NANDrive with advanced NAND management
technology offers two additional protection features—protection zones and password protections.
Protection zones - Up to four independent protection zones can be enabled as either Read-only or
Hidden (Read/Write protected). If the zones are not enabled, the data is unprotected (default con-
figuration).
Password Protection - Requires a customer-unique password to access information within the pro-
tected zones.
