Product Descriptions

LH28F160BJE-BTL90 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 LH28F160BJE-BTL90 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 LH28F160BJE-BTL90 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.
