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.
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”).
