Description

The AT49BV/LV040 are 3-volt-only, 4-megabit Flash memories organized as 524,288

words of 8-bits each. Manufactured with Atmel’s advanced nonvolatile CMOS tech-

nology, the devices offer access times to 120 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.

AT49LV040

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”).
