Features
Description
The AT49BV/LV008A(T) and AT49BV/LV8192A(T) are 3-volt, 8-megabit Flash memo-
ries organized as 1,048,576 words of 8 bits each or 512K words of 16 bits each.
Manufactured with Atmel’s advanced nonvolatile CMOS technology, the devices offer
access times to 70 ns with power dissipation of just 67 mW at 2.7V read. When dese-
lected, the CMOS standby current is less than 50 µA.

... AT49BV/LV8192AT. Once the feature is enabled, the data in the boot block can no longer be erased or pro- grammed when input levels of 5.5V or less are used. Data in the main memory block can still be changed through the regular programming method. To activate the lockout feature, a series of six program commands to specific addresses with specific data must be performed ...
