Overview
Features • Single Supply Voltage, Range 2.
7V to 3.
6V • Single Supply for Read and Write • Fast Read Access Time - 70 ns • Internal Program Control and Timer • 8K bytes Boot Block With Lockout • Fast Erase Cycle Time - 10 seconds • Byte By Byte Programming - 30 µs/Byte typical • Hardware Data Protection • DATA Polling For End Of Program Detection • Low Power Dissipation – 25 mA Active Current – 50 µA CMOS Standby Current • Typical 10,000 Write Cycles 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 mW over the commercial 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.
