... Typical 10,000 Write Cycles Description The AT49F004(T) and AT49F4096A(T) are 5-volt, 4-megabit Flash Memories orga- nized as 524,288 words of 8 bits each or 256K words of 16 bits each. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the devices offer access times with power dissipation of just 275 mW. When deselected, the CMOS standby current is less than 300 A. The device contains a user-enabled “ ...

... The boot sector is designed to con- tain user secure code. For the AT49F4096A(T), the BYTE pin controls whether the device data I/O pins operate in the byte or word config- uration. If the BYTE pin is set at a logic “1” or left open, the device is in word configuration, I/O0 - I/O15 are active and controlled by CE and OE ...

When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins is asserted on the outputs. The outputs are put in the high impedance state whenever high ...
