... Typical 10,000 Write Cycles Description The AT49F008A(T) and AT49F8192A(T) are 5-volt, 8-megabit Flash memories orga- nized as 1,048,576 words of 8 bits each or 512K 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 100 µ ...

... The boot sector is designed to contain user secure code. For the AT49F8192A(T), the BYTE pin controls whether the device data I/O pins operate in the byte or word configuration. 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. If the BYTE pin is set at logic “ ...
