DESCRIPTION

The LH28F800BG-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 LH28F800BG-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. Its boot, parameter and main-blocked architecture, flexible voltage and enhanced cycling capability provide for highly flexible component suitable for portable terminals and personal computers.
