• Embedded Erase
TM
Algorithms
Automatically pre-programs 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
CC
write inhibit
≤
