SHARP’s LH28F320S5NS-L90 Flash memory with Smart 5 technology is a high-density, low-cost, nonvolatile,

read/write storage solution for a wide range of applications. Its symmetrically-blocked architecture, flexible voltage

and extended cycling 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 LH28F320S5NS-L90 offers three levels of protection: absolute protection with VPP at

GND, selective hardware block locking, or flexible software block locking. These alternatives give designers

ultimate control of their code security needs.

The LH28F320S5NS-L90 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.

The LH28F320S5NS-L90 is manufactured on SHARP’s 0.4µm ETOXTM* V process technology. It come in industry-

standard package: the 56-Lead SSOP, ideal for board constrained applications.
