Description
The AT49BV/LV001(N)(T) is a 3-volt-only in-system reprogrammable Flash memory.
Its 1 megabit of memory is organized as 131,072 words by 8 bits. Manufactured with
Atmel’s advanced nonvolatile CMOS technology, the device offers 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. For the
