Description
The AT49BV/LV008 is a 3-volt-only in-system Flash Memory device. Its 8 megabits of
memory is organized as 1,024,576 words by 8 bits. Manufactured with Atmel’s
advanced nonvolatile CMOS technology, the device offers access times to 110 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.
