32-BIT (2Mbit x 16 / 4Mbit x 8 ) Boot Block Flash MEMORY

SHARPs LH28F320BJE-PTTL90 flash memory is a high-density, low-cost, non-volatile read/write storage solution suitable for a variety of applications.
LH28F320BJE-PTTL90 can work at Vcc=2.7V-3.6V and Vccw=2.7V-3.6V or 11.7V-12.3V. Its low-voltage operation capability maximizes battery life and is suitable for cellular phone applications.

Its boot, parameter and main blocking architecture, low voltage and extended loop provide a highly flexible component suitable for portable terminals and personal computers. Its enhanced suspend functionality provides an ideal solution for code + data storage applications.

For secure code storage applications, such as networking, where code is executed directly from flash memory or downloaded to DRAM, the LH28F320BJE-PTTL90 provides four levels of protection: absolute protection for VCcw≤VCCWLK, selective hardware block locking, or flexible software block locking . These alternatives give designers ultimate control over their code security needs.

The LH28F320BJE-PTTL90 is manufactured using Sharp’s 0.25μm ETOXTM* process technology. It comes in an industry-standard package: a 48-pin TSOP, making it ideal for board-constrained applications.
