... Typical 10,000 Write Cycles Description The AT49F1024 and the AT49F1025 are 5-volt-only in-system Flash memories. Their 1 megabit of memory is organized as 65,536 words by 16 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the devices offer access times with power dissipation of just 275 mW over the commercial temperature range. ...

... The Main Memory Erase command is a six-bus cycle operation. The address (5555H) is latched on the falling edge of the sixth cycle while the 30H data input is latched on the rising edge of WE. The main memory erase starts after the rising edge the sixth cycle. Please see main memory erase cycle waveforms. The main memory erase operation is internally controlled ...

... The software product identification exit code should be used to return to standard operation. PRODUCT IDENTIFICATION: The product identification mode identifies the device and manufacturer as Atmel. It may be accessed by hardware or software operation. The hardware operation mode can be used by an external programmer to identify the correct programming algorithm for the Atmel product. ...
