The product is a high-density, low-cost, nonvolatile, read/write storage solution for a wide range of applications.

The product can operate at VCC=2.7V-3.6V and VCCW=2.7V-3.6V or 11.7V-12.3V. Its low voltage operation 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 product offers four levels of protection: absolute protection with VCCW≤VCCWLK, selective hardware block

locking or flexible software block locking. These alternatives give designers ultimate control of their code security needs.

The product is manufactured on SHARP’s 0.25µm ETOXTM* process technology. It come in industry-standard package: the

48-lead TSOP, ideal for board constrained applications.
