GENERAL DESCRIPTION
The F49L320UA/F49L320BA is a 32 Megabit, 3V only CMOS Flash memory device organized as 4M bytes of 8 bits or 2M words of 16bits. This device is packaged in standard 48-pin TSOP. It is designed to be programmed and erased both in system and can in standard EPROM programmers.

   - Word Mode : eight 4K word, sixty-three 32 K word sectors.
• Auto Erase (chip & sector) and Auto Program
   - Any combination of sectors can be erased concurrently;
      Chip erase also provided.
   - Automatically program and verify data at specified address
• Erase Suspend/Erase Resume
   - Suspend or Resume erasing sectors to allow the
      read/program in another sector
• Secured Silicon Sector
   - 128word sector for permanent, secure identification through
      an 8- word random Electronic Serial Number
   - - May be programmed and locked at the factory or by the
   - customer
   - Accessible through a command sequence.
• Ready/Busy (RY/ BY )
   - RY/BY output pin for detection of program or erase operation
      completion
• End of program or erase detection
   - Data polling
   - Toggle bits
• Hardware reset
   - Hardware pin (RESET ) resets the internal state machine to
      the read mode
• Sector Protection /Unprotection
   - Hardware Protect/Unprotect any combination of sectors from
      a program or erase operation.
• Low VCC Write inhibit is equal to or less than 2.0V
• Boot Sector Architecture
   - U = Upper Boot Block
   - B = Bottom Boot Block
• Packages available:
   - 48-pin TSOPI
   - All Pb-free products are RoHS-Compliant
• CFI (Common Flash Interface) complaint
   - Provides device-specific information to the system, allowing
      host software to easily reconfig
