■ GENERAL DESCRIPTION
The MBM29F800TA/BA is a 8M-bit, 5.0 V-only Flash memory organized as 1M bytes of 8 bits each or 512K words of 16 bits each. The MBM29F800TA/BA is offered in a 48-pin TSOP(1) and 44-pin SOP packages. This device is designed to be programmed in-system with the standard system 5.0 V VCC supply. 12.0 V VPP is not required for write or erase operations. The devices can also be reprogrammed in standard EPROM programmers. The standard MBM29LV800TA/BA offers access times 55 ns and 90 ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention the device has separate chip enable (CE), write enable (WE), and output enable (OE) controls.

■ FEATURES
• Single 5.0 V read, write, and erase
   Minimizes system level power requirements
• Compatible with JEDEC-standard commands
   Uses same software commands as E2PROMs
• Compatible with JEDEC-standard world-wide pinouts
   48-pin TSOP(1) (Package suffix: PFTN – Normal Bend Type, PFTR – Reversed Bend Type)
   44-pin SOP (Package suffix: PF)
• Minimum 100,000 write/erase cycles
• High performance
   55 ns maximum access time
• Sector erase architecture
   One 16K byte, two 8K bytes, one 32K byte, and fifteen 64K bytes.
   Any combination of sectors can be concurrently erased. Also supports full chip erase.
• Boot Code Sector Architecture
   T = Top sector
   B = Bottom sector
• Embedded EraseTM* Algorithms
   Automatically pre-programs and erases the chip or any sector
• Embedded ProgramTM* 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
• Low Vcc write inhibit ≤ 3.2 V
• Erase Suspend/Resume
   Suspends the erase operation to allow a read data in another sector within the same device
• Hardware RESET pin
   Resets internal state machine to the read mode
• Sector protection
   Hardware method disables any combination of sectors from write or erase operations
• Temporary sector unprotection
   Temporary sector unprotection via the RESET pin.
