GENERAL DESCRIPTION
The EN29LV640T/B 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 EN29LV640T/B features 3.0V voltage read and write operation, with access times as fast as 70ns 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 70 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.
• High performance program/erase speed
   - Word program time: 8µs typical
   - Sector erase time: 500ms typical
   - Chip erase time: 64s typical
• JEDEC Standard compatible
• Standard DATA# polling and toggle bits
   feature
• Unlock Bypass Program command supported
• 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 FBGA
• Commercial and Industrial Temperature
   Range.
