SHARP’s LH28F320BJE-PTTL90 Flash memory is a high-density, low-cost, nonvolatile, read/write storage solution for a
wide range of applications.
LH28F320BJE-PTTL90 can operate at V
capability realize battery life and suits for cellular phone application.
Its Boot, Parameter and Main-blocked architecture, low voltage and extended cycling provide for highly flexible component
suitable for portable terminals and personal computers. 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 LH28F320BJE-PTTL90 offers four levels of protection: absolute protection with V
hardware block locking or flexible software block locking. These alternatives give designers ultimate control of their code
security needs.
The LH28F320BJE-PTTL90 is manufactured on SHARP’s 0.25µm ETOX
standard package: the 48-lead TSOP, ideal for board constrained applications.
