Product Description
The Greenliant PATA NAND Controller is the heart of a high-
performance, flash media-based data storage system. The
NAND Controller recognizes the control, address and data
signals on the ATA/IDE bus and translates them into
memory accesses to the standard NAND-type flash media.
The GLS55LD040M device supports Single-Level Cell (SLC)
and Multi-Level Cell (MLC) flash media. This technology is
ideal for solid state mass storage applications offering
expanded functionality, flexible capacity scaling capabilities
and lower power consumption.
The Greenliant PATA NAND Controller supports standard
ATA/IDE protocols with up to PIO Mode-4, Multi-word DMA
Mode-2, and Ultra DMA Mode-6 interface. It directly supports
up to 16 flash media devices or, through simple decoding
logic, supports up to 64 flash media devices.
The PATA NAND Controller uses Embedded Flash memory
and is factory pre-programmed with a flash file system. Upon
initial power-on, the PATA NAND Controller recognizes
attached flash media devices, sets up a bad block table,
executes all necessary handshaking routines for flash media
support and performs the low level format.
For added manufacturing flexibility, system debug, re-
initialization and user customization is accomplished through
the ATA/IDE interface.
For confidential information stored in the flash media, the
GLS55LD040M provides exceptional security protection.
Four password-protected protection zones can be set to
Read/Write, Read-only or Hidden (Read-disabled). The
NAND Controller also provides a WP#/PD# pin to protect
critical information stored in the flash media from
unauthorized overwrites.
The GLS55LD040M is available in an industry-standard,
145-ball TFBGA package for easy integration into a surface
mount technology manufacturing process.
