1M bit (64K x 16), 5-Volt Read and 5-Volt Write Flash

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. 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-byword 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.
