SHARP's LH28F160BJHE-BTLZD Flash memory is a high-density, low-cost, nonvolatile, read/write storage solution for a
wide range of applications.
LH28F160BJHE-BTLZD can operate at V
CC
=2.7V-3.6V and V
CCW
=2.7V-3.6V or 11.7V-12.3V. Its low voltage operation
capability realizes long 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 LH28F160BJHE-BTLZD offers four levels of protection: absolute protection with V
CCW
V
CCWLK
, selective
hardware block locking or flexible software block locking. These alternatives give designers ultimate control of their code
security needs.
The LH28F160BJHE-BTLZD is manufactured on SHARP's 0.25m ETOX
TM*
process technology. It come in industry-
standard package: the 48-lead TSOP, ideal for board constrained applications.
