Its 2 megabits of memory is organized as 262,144 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 AT49BV/LV002 is deselected, the CMOS standby current is less than 50 mA. For the
