■ GENERAL DESCRIPTION

The MBM29LV400TC/BC are a 4M-bit, 3.0 V-only Flash memory organized as 512K bytes of 8 bits each or 256K words of 16 bits each. The MBM29LV400TC/BC are offered in a 48-pin TSOP(1), 44-pin SOP, 48-pin CSOP, and 48-ball FBGA packages. These devices are designed to be programmed in-system with the standard system 3.0 V VCC supply. 12.0 V VPP and 5.0 V VCC are not required for write or erase operations. The devices can also be reprogrammed in standard EPROM programmers.

■ FEATURES

44-pin SOP (Package suffix: PF)

48-pin CSOP (Package suffix: PCV)

48-ball FBGA (Package suffix: PBT)

48-ball SCSP (Package suffix: PW)

? Minimum 100,000 program/erase cycles

? High performance

55 ns maximum access time

? Sector erase architecture

One 8K word, two 4K words, one 16K word, and seven 32K words sectors in word mode

One 16K byte, two 8K bytes, one 32K byte, and seven 64K bytes sectors in byte mode

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 preprograms 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

? Automatic sleep mode

When addresses remain stable, automatically switch themselves to low power mode

? Low VCC write inhibit ≤ 2.5 V

? Erase Suspend/Resume

Suspends the erase operation to allow a read in another sector within the same device

? Sector protection

Hardware method disables any combination of sectors from program or erase operations

? Sector Protection set function by Extended sector Protect command

? Fast Programming Function by Extended Command

? Temporary sector unprotection

Temporary sector unprotection via the RESET pin
