... Typical 10,000 Write Cycles Description The AT49F4096 is a 5-volt only, 4-megabit Flash Memory organized as 256K words of 16 bits each. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times with power dissipation of just 275 mW. When deselected, the CMOS standby current is less than 300 A. ...

... To allow for simple in-system reprogrammability, the AT49F4096 does not require high input voltages for pro- gramming. 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; it has standard CE, OE, and WE inputs to avoid bus conten- tion ...

... DATA polling may begin at any time during the program cycle. TOGGLE BIT: In addition to DATA polling the AT49F4096 provides another method for determining the end of a pro- gram or erase cycle. During a program or erase operation, successive attempts to read data from the device will result in I/O6 toggling between one and zero ...

... Examining the toggle bit may begin at any time during a program cycle. HARDWARE DATA PROTECTION: Hardware features protect against inadvertent programs to the AT49F4096 in the following ways: (a) V sense— (typical), the program function is inhibited; (b) V Command Definition (in Hex) 1st Bus ...
