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”)
