■ 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
