SHARP’s LH28F800BVE-BV85 Flash memory with Smart5 technology is a high-density, low-cost, nonvolatile, read/write
storage solution for a wide range of applications. LH28F800BVE-BV85 can operate at V
CC
=4.5V-5.5V and V
PP
=4.5V-5.5V.
Its low voltage operation capability realize battery life and suits for cellular phone application.
Its Boot, Parameter and Main-blocked architecture, flexible 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 LH28F800BVE-BV85 offers two levels of protection: absolute
protection with V
PP
at GND, selective hardware boot block locking. These alternatives give designers ultimate control of their
code security needs.
The LH28F800BVE-BV85 is manufactured on SHARP’s 0.35µm ETOX
TM*
process technology. It come in industry-standard
package: the 48-lead TSOP ideal for board constrained applications.
