• Write protection
– Software write protection applicable to every
64KB sector via volatile lock bit
– Hardware write protection: protected area size
defined by five nonvolatile bits (BP0, BP1, BP2,
BP3, and TB)
– Additional smart protections, available upon request
• Electronic signature
– JEDEC-standard 2-byte signature (BA20h)
