Description
The AT49BV8192 and AT49LV8192 are 3-volt, 8-megabit Flash Memories organized
as 512K words of 16 bits each. Manufactured with Atmel’s advanced nonvolatile
CMOS technology, the devices offer access times to 120 ns with power dissipation of
just 67 mW at 2.7V read. When deselected, the CMOS standby current is less than 50
µA.
