• Minimum 100,000 program/erase cycles
• High performance
70 ns maximum access time
• Sector erase architecture
One 8K word, two 4K words, one 16K word, and seven 32K words sectors in word mode
One 16K byte, two 8K bytes, one 32K byte, and seven 64K bytes sectors in byte mode
Any combination of sectors can be concurrently erased. Also supports full chip erase
• Boot Code Sector Architecture
T = Top sector
B = Bottom sector
• Embedded Erase
TM
Algorithms
Automatically preprograms and erases the chip or any sector
• Embedded Program
TM
Algorithms
Automatically writes and verifies data at specified address
• Data Polling and Toggle Bit feature for detection of program or erase cycle completion
• Ready/Busy output (RY/BY)
Hardware method for detection of program or erase cycle completion
• Automatic sleep mode
When addresses remain stable, automatically switch themselves to low power mode
• Low V
