GENERAL DESCRIPTION

The MBM29DL400TC/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 MBM29DL400TC/BC are offered in a 48-pin TSOP(I) package. 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

? Simultaneous operations

Read-while-Erase or Read-while-Program

? Compatible with JEDEC-standard commands

Uses same software commands as E2PROMs

? Compatible with JEDEC-standard world-wide pinouts (Pin compatible with MBM29LV400TC/BC)

48-pin TSOP(I) (Package suffix: PFTN – Normal Bend Type, PFTR – Reversed Bend Type)

? Minimum 100,000 program/erase cycles

? High performance

55 ns maximum access time

? Sector erase architecture

Two 16K byte, four 8K bytes, two 32K byte, and six 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

? 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 protection command

? Fast Programming Function by Extended Command

? Temporary sector unprotection

Temporary sector unprotection via the RESET pin.
