GENERAL DESCRIPTION
The EN29LV640A is a 64-Megabit, electrically erasable, read/write non-volatile flash memory, organized as 8,388,608 bytes or 4,194,304 words. Any word can be programmed typically in 8µs. The EN29LV640A features 3.0V voltage read and write operation, with access times as fast as 90ns to eliminate the need for WAIT states in high-performance microprocessor systems.

FEATURES
• Single power supply operation
   - Full voltage range: 2.7 to 3.6 volts read and
      write operations
• High performance
   - Access times as fast as 90 ns
• Low power consumption (typical values at 5
   MHz)
   - 9 mA typical active read current
   - 20 mA typical program/erase current
   - Less than 1 μA current in standby or automatic
      sleep mode.
• Flexible Sector Architecture:
   - Eight 8-Kbyte sectors, One hundred and
      twenty-seven 32K-Word / 64K-byte sectors.
   - 8-Kbyte sectors for Top or Bottom boot.
   - Sector/Sector Group protection:
      Hardware locking of sectors to prevent
      program or erase operations within individual
      sectors
      Additionally, temporary Sector Group
      Unprotect allows code changes in previously
      locked sectors.
• Secured Silicon Sector
   - Provides a 128-words area for code or data
      that can be permanently protected.
   - Once this sector is protected, it is prohibited
      to program or erase within the sector again.
• High performance program/erase speed
   - Word program time: 8µs typical
   - Sector erase time: 100ms typical
   - Chip erase time: 16s typical
• JEDEC Standard compatible
• Standard DATA# polling and toggle bits
   feature
• Erase Suspend / Resume modes:
   Read and program another Sector during
   Erase Suspend Mode
• Support JEDEC Common Flash Interface
   (CFI).
• Low Vcc write inhibit < 2.5V
• Minimum 100K program/erase endurance
   cycles.
• RESET# hardware reset pin
   - Hardware method to reset the device to read
      mode.
• WP#/ACC input pin
   - Write Protect (WP#) function allows
      protection of outermost two boot sectors,
      regardless of sector protect status
   - Acceleration (ACC) function provides
      accelerated program times
• Package Options
   - 48-pin TSOP (Type 1)
   - 48 ball 6mm x 8mm TFBGA
• Industrial Temperature Range.
