Features
Description
The AT49BV/LV4096A is a 3-volt, 4-megabit Flash memory organized as 524,288
words of 8 bits each or 256K words of 16 bits each. Manufactured with Atmel’s
advanced nonvolatile CMOS technology, the device offers access times to 70 ns with
power dissipation of just 67 mV at 2.7V read. When deselected, the CMOS standby
current is less than 50 µA.
The device contains a user-enabled “boot block” protection feature. The
AT49BV/LV4096A locates the boot block at lowest order addresses (“bottom boot”).
To allow for simple in-system reprogrammability, the AT49BV/LV4096A 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 con-
tention. Reprogramming the AT49BV/LV4096A is performed by first erasing a block of
data and then programming on a byte-by-byte or word-by-word basis.
