• 8 words Page
• Compatible with JEDEC-standard commands
Uses same software commands as E²PROMs
• Minimum 100,000 Program/Erase Cycles
• Sector Erase Architecture
Eight 8 Kbytes, a hundred twenty-six 64 Kbytes, eight 8 Kbytes sectors.
Any combination of sectors can be concurrently erased. Also supports full chip erase
• Dual Boot Block
Sixteen to 8Kbytes boot block sectors, eight at the top of the address range and eight at the bottom of the
address range
• HiddenROM Region
256 byte of HiddenROM, accessible through a new “HiddenROM Enable” command sequence
Factory serialized and protected to provide a secure electronic serial number (ESN)
• WP/ACC Input Pin
At VIL, allows protection of “outermost” 2×4 K words on both ends of boot sectors, regardless of sector pro-
tection/unprotection status
At VIH, allows removal of boot sector protection
At VACC, increases program performance
• Embedded Erase^TM *² Algorithms
Automatically preprograms and erases the chip or any sector
• Embedded Program^TM *² 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, the device automatically switches itself to low power mode
• Program Suspend/Resume
Suspends the program operation to allow a read in another byte
• Erase Suspend/Resume
Suspends the erase operation to allow a read data and/or program in another sector within the same device
• New Sector Protection
Persistent Sector Protection
Password Sector Protection
