GENIUNE Atmel AT49F512 70TC 0012 512k (64k x 8) 5-volt only Flash Memory TSOP

Description

Geniune Atmel product
.
Description:
The AT49F512 is a 5-volt-only in-system programmable and erasable Flash Memory.
Its 512K of memory is organized as 65,536 words by 8 bits. Manufactured with
Atmel’s advanced nonvolatile CMOS technology, the devices offer access times to 50
ns with a power dissipation of just 165mW over the commercial temperature range.
When the device is deselected, the CMOS standby current is less than 100 μA.
To allow for simple in-system re-programmability, the AT49F512 does not require high
input voltages for programming. Five-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. Reprogramming the AT49F512 is performed by erasing the
entire 512K of memory and then programming on a byte by byte basis. The typical
byte programming time is a fast 10 μs. The end of a program cycle can be optionally
detected by the DATA
polling feature. Once the end of a
byte program cycle has been detected, a new access for a
read or program can begin. The typical number of program
and erase cycles is in excess of 10,000 cycles.
