Advance Information
Capacity Specification
Table 2 shows the default capacity and specific settings for heads, sectors, and cylinders. At produc-
tion time, the manufacturer can change the default settings in the drive ID table by changing the Cylin-
ders-Heads Sectors configuration. If the total number of bytes configured is less than the default
amount, the remaining space could be used as spare blocks to increase the flash drive endurance. It
should also be noted that if the initialized total flash drive capacity exceeds the total bytes shown in
Table 2, the flash drive endurance will be reduced.
Configurable Write Protect/Power-down Modes
The WP#/PD# pin can be used for either Write Protect mode or Power-down mode, but only one mode
is active at any time. Either mode can be selected through the host command, Set-WP#/PD#-Mode.
Once the mode is set with this command, the device will stay in the configured mode until the next time
this command is issued. Power-off or reset will not change the configured mode.
Write Protect Mode
When the device is configured in the Write Protect mode, the WP#/PD# pin offers extended data pro-
tection. This feature can be either selected through a jumper or host logic to protect the stored data
from inadvertent system writes or erases, and viruses. The Write Protect feature protects the full
address space of the data stored on the flash media.
In the Write Protect mode, assert the WP#/PD# pin prior to issuing all destructive commands: Erase-
Sector, Format-Track, Write-DMA, Write-Multiple, Write-Sector(s), or Write-Verify. This will force the
NANDrive to reject any destructive commands from the ATA interface. All destructive commands will
return 51H in the Status register and 04H in the Error register signifying an invalid command. All non-
destructive commands will be executed normally.
