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 technol-
ogy, 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. The
AT49BV/LV040 locates the boot block at lowest order addresses (“bottom boot”).
