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 VPP 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.
