DESCRIPTION

The LH28F800SG-L flash memory with Smart Voltage technology is a high-density, low-cost, nonvolatile, read/write storage solution for a wide range of applications. The LH28F800SG-L can operate at VCC = 2.7 V and VPP = 2.7 V. Its low voltage operation capability realizes longer battery life and suits for cellular phone application.
