■GENERAL DESCRIPTION
●The MBM29F080A is a 8 M-bit, 5.0 V-Only Flash memory organized as 1 M bytes of 8 bits each. The 1 M bytes of data is divided into 16 sectors of 64 K bytes for flexible erase capability. The 8 bit of data will appear on DQ0 to DQ7. The MBM29F080A is offered in a 48-pin TSOP(I), 40-pin TSOP, and 44-pin SOP packages. This device is designed to be programmed in-system with the standard system 5.0 V VCCsupply. A 12.0 V VPPis not required for program or erase operations. The device can also be reprogrammed in standard EPROM programmers.
●■FEATURES
●• Single 5.0 V read, write, and erase
● Minimizes system level power requirements
●• Compatible with JEDEC-standard commands
● Pinout and software compatible with single-power supply Flash
● Superior inadvertent write protection
●• 48-pin TSOP(I) (Package Suffix: PFTN-Normal Bend Type, PFTR-Reverse Bend Type)
● 40-pin TSOP(I) (Package Suffix: PTN-Normal Bend Type, PTR-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
● Uniform sectors of 64 K bytes each
● Any combination of sectors can be erased. Also supports full chip erase.
●• Embedded Erase™ Algorithms
● Automatically pre-programs and erases the chip or any sector
●• Embedded Program™ Algorithms
● Automatically programs and verifies data at specified address
●•DataPolling 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 VCCwrite inhibit ≤3.2 V
●• Hardware RESETpin
● Resets internal state machine to the read mode
●• Erase Suspend/Resume
● Supports reading or programming data to a sector not being erased
●• Sector group protection
● Hardware method that disables any combination of sector groups from write or erase operation (a sector group consists of 2 adjacent sectors of 64 K bytes each)
●• Temporary sector groups unprotection
● Temporary sector unprotection via the RESET pin
