LH28F320S3TD-L10
DESCRIPTION
The LH28F320S3TD-L10 Dual Work flash memory
with Smart 3 technology is a high-density, low-cost,
nonvolatile, read/write storage solution for a wide
range of applications, having high programming
performance is achieved through highly-optimized
page buffer operations. Its symmetrically-blocked
architecture, flexible voltage and enhanced cycling
capability provide for highly flexible component
suitable for resident flash arrays, SIMMs and
memory cards. Its enhanced suspend capabilities
provide for an ideal solution for code + data storage
applications. For secure code storage applications,
such as networking, where code is either directly
executed out of flash or downloaded to DRAM, the
LH28F320S3TD-L10 offers three levels of
protection : absolute protection with V
PP
at GND,
selective hardware block locking, or flexible
software block locking. These alternatives give
designers ultimate control of their code security
needs. LH28F320S3TD-L10 is conformed to the
flash Scalable Command Set (SCS) and the
Common Flash Interface (CFI) specification which
enable universal and upgradable interface, enable
the highest system/device data transfer rates and
minimize device and system-level implementation
costs.
