Description

The AT49F1024A is a 5-volt-only in-system Flash memory organized as 65,536 words

by 16 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the

devices offer access times to 45 ns with power dissipation of just 275 mW over the

commercial temperature range. When the device is deselected, the CMOS standby

current is less than 100 µA.

AT49F1024A

To allow for simple in-system reprogrammability, the AT49F1024A 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 AT49F1024A is performed by erasing a

block of data (entire chip or main memory block) and then programming on a word-by-

word basis. The typical word 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.
