4 GByte NANDrive
SST85LD1004T
Fact Sheet
The SST85LD1004T NANDrive™ solid-state (SSD) drive combines a NAND controller and
4 GBytes of NAND flash in a multi-chip package. It provides complete ATA/IDE hard disk
drive functionality in a small package for easy, space-saving mounting to a system mother-
board. This makes the SST85LD1004T NANDrive SSD the ideal data storage solution for
mobile and embedded electronic products that require smaller and more reliable storage.

Pin Assignments
Fact Sheet
The signal/pin assignments are listed in Figure 2. Low active signals have a “#” suffix. Pin types are
Input, Output, or Input/Output. Signals whose source is the host are designated as inputs while signals
that the NANDrive sources are outputs.
The NANDrive functions in ATA mode, which is compatible with IDE hard disk drives.

SST85LD1004T
Fact Sheet
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. Always provide access to the SCI
interface in the PCB design to aid in design validation.
Lifetime Expectancy
NANDrive with advanced NAND management technology significantly extends the life of a product
with its extensive ECC, advanced wear-leveling, and data scan and Refresh (DSR) algorithms. Each
NANDrive device is partitioned into four wear-leveling groups. See Table 5 for the group size of each
product.
Each NANDrive wear-leveling group can receive at least 100 million write cycles from the host. With
four wear-leveling groups in each product, 400 million write cycles per product is possible when host
writes are evenly distributed across groups.
For applications where data security is essential, NANDrive with advanced NAND management tech-
nology 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 Hid-
den (Read/Write protected). If the zones are not enabled, the data is unprotected (default configura-
tion).
Password Protection - Requires a customer-unique password to access information within the pro-
tected zones.
