Part Number : AT49BV512-15PI
Function : 512K (64K x 8) single 2.7-volt Battery-Voltage Flash Memory
Package : DIP 32 Pin Type
Maker : Atmel Corporation
Pinouts : 
Description :
The AT49BV512-15PI, AT49BV512 is a 3-volt only, 512K Flash memories organized as 65,536 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 devices are deselected, the CMOS standby
current is less than 50 µA.
To allow for simple in-system reprogrammability, the AT49BV512 does not require
high input voltages for programming. Three-volt only commands determine the read
and programming operation of the device. Reading data out of the device is similar to
reading from an EPROM.
Features :
• Single Supply Voltage, Range 2.7V to 3.6V
• Single Supply for Read and Write
• Fast Read Access Time - 120 ns
• Internal Program Control and Timer
• 8K bytes Boot Block With Lockout
• Fast Erase Cycle Time - 10 seconds
