Product Description
The GLS85LD0512, GLS85LD1001T and GLS85LD1002U NANDrive™ solid-state drives (SSD)
are high-performance, fully-integrated, embedded flash solid state drives. They combine an inte-
grated ATA Controller and either 512 MByte, 1 GByte, or 2 GByte of NAND Flash in a multi-chip
package. These products are ideal for industrial grade solid state mass storage applications offer-
ing new and expanded functionality while enabling cost effective designs.
ATA-based solid state mass storage technology is widely used in portable and desktop computers,
digital cameras, music players, handheld data collection scanners, cellular phones, PCS phones,
PDAs, handy terminals, personal communicators, robotics, audio recorders, monitoring devices,
and set-top boxes.
Greenliant NANDrive is a single device, solid state drive designed for embedded ATA/IDE protocol
systems and supports standard ATA/IDE protocol with up to PIO Mode-6, Multi-word DMA Mode-4
and Ultra DMA Mode-4 interface. The built in microcontroller and file management firmware com-
municates with ATA standard interfaces; thereby eliminating the need for additional or proprietary
software such as Flash File System (FFS) and Memory Technology Driver (MTD) software.
The GLS85LD0512 / GLS85LD1001T / GLS85LD1002U NANDrives provide complete IDE Hard
Disk Drive functionality and compatibility in a 12mm x 24mm BGA package for easy, space saving
mounting to a system motherboard. It is a perfect solution for portable, consumer electronic prod-
ucts requiring smaller and more reliable data storage.
The NANDrive provides a WP#/PD# pin to protect critical information stored in the flash media
from unauthorized overwrites.
The NANDrive is pre-programmed with a 10-byte unique serial ID. For even greater system secu-
rity, the user has the option of programming an additional 10 Bytes of ID space to create a unique,
20-byte ID.
NANDrive SSD is available with advanced NAND management technology, a NAND memory
management technology that enhances data security, significantly improves endurance, and accu-
rately predicts the minimum life span of NAND flash devices. Advanced NAND management tech-
nology combines NAND controller hardware error correction, advanced wear leveling algorithms,
and bad block management to extend the life of the product.

Data Sheet
General Description
Each NANDrive contains an integrated ATA Controller and one or more NAND Flash dice in a
LBGA package. Refer to Figure 1 for the NANDrive block diagram.
Performance-optimized NANDrive
The heart of the NANDrive is the ATA Flash Disk Controller which translates standard ATA signals
into flash media data and control signals. The following components contribute to the NANDrive’s
operation.
Microcontroller Unit (MCU)
The MCU translates ATA/IDE commands into data and control signals required for flash media oper-
ation.
Internal Direct Memory Access (DMA)
The NANDrive uses internal DMA allowing instant data transfer from buffer to flash media. This
implementation eliminates microcontroller overhead associated with the traditional, firmware-
based approach, thereby increasing the data transfer rate.
Power Management Unit (PMU)
The power management unit controls the power consumption of the NANDrive. The PMU dramat-
ically reduces the power consumption of the NANDrive by putting the part of the circuitry that is not
in operation into sleep mode.
SRAM Buffer
A key contributor to the NANDrive performance is an SRAM buffer. The buffer optimizes the host’s
data transfer to and from the flash media.
Embedded Flash File System
The embedded flash file system is an integral part of the NANDrive. It contains MCU firmware that
performs the following tasks:
1.
2.
3.
Translates host side signals into flash media writes and reads.
Provides dynamic flash media wear leveling to spread the flash writes to increase the
longevity of flash media.
Keeps track of data file structures.
Error Correction Code (ECC)
High performance is achieved through optimized hardware error detection and correction.
Serial Communication Interface (SCI)
The Serial Communication Interface (SCI) is designed for manufacturing error reporting. Always
provide SCI interface access to PCB design to aid in design validation.

Data Sheet
Multi-tasking Interface
The multi-tasking interface enables fast, sustained write performance by allowing concurrent
Read, Program, and Erase operations to multiple flash media devices.
Advanced NAND Management
Technology
Advanced NAND management technology balances the wear on erased blocks with an advanced
wear-leveling scheme which provides a minimum of 100 million product write cycles. Advanced
NAND management technology tracks the number of program/erase cycles within a group. When
the host updates data, higher priority is given to the less frequently written erase blocks; thereby,
evenly distributing host writes within a wear-leveling group.
Advanced NAND management technology enhances NANDrive security with password protection
and four independent protection zones which can be set to Read-only or Hidden.

Pin Assignments
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.
