DESCRIPTION

The LH28F800BG-L/BGH-L flash memories with SmartVoltage technology are high-density, low-cost, nonvolatile, read/write storage solution for a wide range of applications. The LH28F800BG-L/BGH-L can operate at VCC = 2.7 V and VPP = 2.7 V. Their low voltage operation capability realizes longer battery life and suits for cellular phone application.
