MBM29DL322TD-80PFTR中文资料富士通数据手册PDF规格书

■ GENERAL DESCRIPTION

The MBM29DL32XTD/BD are a 32M-bit, 3.0 V-only Flash memory organized as 4M bytes of 8 bits each or 2M words of 16 bits each. The MBM29DL32XTD/BD are offered in a 48-pin TSOP(I) and FBGA Package. These devices are designed to be programmed in-system with the standard system 3.0 V VCC supply. 12.0 V VPPand 5.0 V VCCare not required for write or erase operations. The devices can also be reprogrammed in standard EPROM programmers.

■ FEATURES

• 0.33 µm Process Technology

• Simultaneous Read/Write operations (dual bank)

Multiple devices available with different bank sizes (Refer to Table 1)

Host system can program or erase in one bank, then immediately and simultaneously read from the other bank

Zero latency between read and write operations

Read-while-erase

Read-while-program

• 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 TSOP(I) (Package suffix: PFTN – Normal Bend Type, PFTR – Reversed Bend Type)

57-ball FBGA (Package suffix: PBT)

• Minimum 100,000 program/erase cycles

• High performance

80 ns maximum access time

• Sector erase architecture

Eight 4K word and sixty-three 32K word sectors in word mode

Eight 8K byte and sixty-three 64K byte 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

• Hidden ROM (Hi-ROM) region

64K byte of Hi-ROM, accessible through a new “Hi-ROM Enable” command sequence

Factory serialized and protected to provide a secure electronic serial number (ESN)

• WP/ACC input pin

At VIL, allows protection of boot sectors, regardless of sector protection/unprotection status

At VIH, allows removal of boot sector protection

At VACC, increases program performance

• Embedded EraseTM Algorithms

Automatically pre-programs and erases the chip or any sector

• Embedded ProgramTM Algorithms

Automatically writes 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

• Automatic sleep mode

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

• Low VCCwrite inhibit ≤2.5 V

• Erase Suspend/Resume

Suspends the erase operation to allow a read data and/or program in another sector within the same device

• Sector group protection

Hardware method disables any combination of sector groups from program or erase operations

• Sector Group Protection Set function by Extended sector group protection command

• Fast Programming Function by Extended Command

• Temporary sector group unprotection

Temporary sector group unprotection via the RESETpin.

• In accordance with CFI (Common Flash Memory Interface)
