... Typical 10,000 Write Cycles Description The AT49BV8192 and AT49LV8192 are 3-volt, 8-megabit Flash Memories organized as 512K words of 16 bits each. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the devices offer access times to 120 ns with power dissipation of just 2.7V read. When deselected, the CMOS standby current is less than 50 A ...

... Device Operation READ: The AT49BV/LV8192 is accessed like an EPROM. When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins is asserted on the outputs. The outputs are put in the high impedance state whenever high. This dual-line control gives designers flexibility in preventing bus conten- tion ...

... Once the feature is enabled, the data in the boot block can no longer be erased or programmed 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 activate the lockout feature, a series of six program commands to specific addresses with specific data must be performed ...

... SA = 79XXX for MAIN MEMORY ARRAY 5. When the boot block programming lockout feature is not enabled, the boot block and the main memory block will erase together (form the same sector erase command). Once the boot region has been protected, only the main memory array sector will erase when its sector erase command is issued ...
