SHARP’s LH28F008SCT-L85 Flash memory with SmartVoltage 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 LH28F008SCT-L85 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 LH28F008SCT-L85 is manufactured on SHARP’s 0.38µm ETOX
TM
process technology. It come in
industry-standard package: the 40-lead TSOP, ideal for board constrained applications. Based on the 28F008SA
architecture, the LH28F008SCT-L85 enables quick and easy upgrades for designs demanding the state-of-the-art.
