MBM29LV800BA-90PFTN

CMOS 8M 1M x 8/512K x 16 Bit FLASH MEMORY

■ GENERAL DESCRIPTION

The MBM29LV800TA/BA are a 8M-bit, 3.0 V-only Flash memory organized as 1M bytes of 8 bits each or 512K words of 16 bits each. The MBM29LV800TA/BA are offered in a 48-pin TSOPI, 44-pin SOP, 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

• Single 3.0 V read, program, 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 TSOPI Package suffix: PFTN – Normal Bend Type, PFTR – Reversed Bend Type

   44-pin SOP Package suffix: PF

   48-ball FBGA Package suffix: PBT

• Minimum 100,000 program/erase cycles

• High performance

   70 ns maximum access time

• Sector erase architecture

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

   One 16K byte, two 8K bytes, one 32K byte, and fifteen 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 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

• 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

• Temporary sector unprotection

   Temporary sector unprotection via the RESET pin
