SHARP’s LH28F320S3HNS-ZM Flash memory with Smart 3 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 LH28F320S3HNS-ZM 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.
The LH28F320S3HNS-ZM 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 LH28F320S3HNS-ZM is manufactured on SHARP’s 0.4μm ETOX TM * V process technology. It come in
industry-standard package: the 56-Lead SSOP, ideal for board constrained applications.
