Flash Memory Features
Architectural Advantages

• Simultaneous Read/Write operations
• Data can be continuously read from one bank while executing erase/program functions in another bank.
• Zero latency between read and write operations
• Flexible Bank™ architecture
• Read may occur in any of the three banks not being written or erased.
• Four banks may be grouped by customer to achieve desired bank divisions.
• Manufactured on 0.13 µm process technology
• SecSi™ (Secured Silicon) Sector: Extra 256 Byte sector
• Factory locked and identifiable: 16 bytes available for secure, random factory Electronic Serial Number; verifiable as factory locked through autoselect function. ExpressFlash option allows entire sector to be available for factory-secured data
• Customer lockable: Sector is one-time programmable. Once sector is locked, data cannot be changed.
• Zero Power Operation
• Sophisticated power management circuits reduce power consumed during inactive periods to nearly zero.
• Boot Sectors
  • Top and bottom boot sectors in the same device
• Compatible with JEDEC standards
• Pinout and software compatible with single-power-supply flash standard

  • Hardware method for detecting program or erase cycle completion
• Hardware reset pin (RESET#)
  • Hardware method of resetting the internal state machine to the read mode
• WP#/ACC input pin
  • Write protect (WP#) function protects sectors 0, 1, 140, and 141, regardless of sector protect status
  • Acceleration (ACC) function accelerates program timing
• Sector protection
• Hardware method of locking a sector, either in-system or using programming equipment, to prevent any program or erase operation within that sector
• Temporary Sector Unprotect allows changing data in protected sectors in-system
