Description
The AT49BV4096 and AT49LV4096 are 3-volt, 4-megabit Flash Memories organized
as 256K 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.
To allow for simple in-system reprogrammability, the AT49BV4096/LV4096 does not
require high input voltages for programming. Reading data out of the device is similar
to reading from an EPROM; it has standard CE, OE, and WE inputs to avoid bus
