■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
