■ DESCRIPTION

The MBM29BS/FS12DH is a 128 Mbit, 1.8 Volt-only, Burst mode and dual operation Flash memory organized as 8M words of 16 bits each. The device offered in a 80-ball FBGA package. This device is designed to be programmed in-system with the standard system 1.8 V VCC supply. 12.0 V VPP and 5.0 V VCC are not required for write or erase operations. The device can also be programmed in standard EPROM programmers.

■ FEATURES

? 0.13 μm process technology

? Single 1.8 V read, program and erase (1.65 V to 1.95 V)

? Simultaneous Read/Write operation (Dual Bank)

? FlexBankTM*1

Bank A: 16 Mbit (4 Kwords × 8 and 32 Kwords × 31)

Bank B: 48 Mbit (32 Kwords × 96)

Bank C: 48 Mbit (32 Kwords × 96)

Bank D: 16 Mbit (4 Kwords × 8 and 32 Kwords × 31)

? Enhanced VI/OTM*2 (VCCQ) Feature

Input/ Output voltage generated on the device is determined based on the VI/O level

? High Performance Burst frequency reach at 66 MHz

Burst access times of 11 ns @ 30 pF at industrial temperature range

Asynchronous random access times of 50 ns (at 30 pF)

Synchronous latency of 56 ns with 1.8 V VCCQ for Handshaking mode

? Programmable Burst Interface

Linear Burst: 8, 16, and 32 words with wrap-around

? Compatible with JEDEC-standard commands

Uses same software commands as E2PROMs

? Minimum 100,000 program/erase cycles

? Sector Erase Architecture

Eight 4 Kwords, two hundred fifty-four 32 Kwords sectors, eight 4 Kwords sectors.

Any combination of sectors can be concurrently erased. Also supports full chip erase.

? HiddenROM region

64 words for factory and 64 words for customer of HiddenROM, accessible through a new “HiddenROM Enable”

command sequence

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

? Write Protect Pin (WP)

At VIL, allows protection of “outermost” 4×4 K words on low, high end or both ends of boot sectors, regardless

of sector protection/unprotection status

? Accelerate Pin (ACC)

At VACC, increases program performance. ; all sectors locked when ACC = VIL

? Embedded EraseTM*2 Algorithms

Automatically preprograms and erases the chip or any sector

? Embedded ProgramTM*2 Algorithms

Automatically writes and verifies data at specified address

? Data Polling and Toggle Bit feature for detection of program or erase cycle completion

? Ready Output (RDY)

In Synchronous Mode, indicates the status of the Burst read.

In Asynchronous Mode, indicates the status of the internal program and erase function.

? Automatic sleep mode

When address remain stable, the device automatically switches itself to low power mode

? Erase Suspend/Resume

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

? In accordance with CFI (Common Flash Interface)

? Hardware reset pin (RESET)

Hardware method to reset the device for reading array data

? Sector Protection

Persistent sector protection

Password sector protection

ACC protects all sectors

WP protects the outermost 4 x 4 K words on both ends of boot sectors, regardless of sector protection /

unprotection status.

? Handshaking feature available (MBM29FS12DH)

Provides host system with minimum possible latency by monitoring RDY

? CMOS compatible inputs, CMOS compatible outputs
