Description
The AT49BV020 and the AT49LV020 are 3-volt-only, 2 megabit Flash memories organized as 262,144 words of 8 bits each. Manufactured with Atmel's advanced nonvolatile CMOS technology, the devices offer access times to 70 ns with power dissipation of just 90 m W over the mercial temperature range. When the device is deselected, the CMOS standby current is less than 50 µA.
To allow for simple in-system reprogrammability, the AT49BV/LV020 does not require high input voltages for programming....
