Description

The AT49BV/LV040(T) are 3-volt only, 4-megabit Flash memories organized as

524,288 words of 8-bits each. Manufactured with Atmel’s advanced nonvolatile CMOS

technology, the devices offer access times to 70 ns with power dissipation of just

90 mW over the commercial temperature range. When the device is deselected, the

CMOS standby current is less than 50 µA.

The device contains a user-enabled “boot block” protection feature. Two versions of

the feature are available: the AT49BV/LV040 locates the boot block at lowest order

addresses (“bottom boot”); the AT49BV/LV040T locates it at highest order addresses

(“top boot”).
