MBM29LV017-80/-90/-12
s FEATURES
• Address specification is not necessary during command sequence
• 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
40-pin TSOP (I) (Package suffix: PTN-Normal Bend Type, PTR-Reversed Bend Type)
48-ball FBGA (Package suffix: PBT)
• Minimum 100,000 program/erase cycles
• High performance
80 ns maximum access time
• Sector erase architecture
Uniform sectors of 64K bytes each
Any combination of sectors can be concurrently erased. Also supports full chip erase
• Embedded EraseTM Algorithms
Automatically pre-programs and erases the chip or any sector
• Embedded programTM Algorithms
Automatically programs 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 switches themselves to low power mode
• Low VCC write inhibit ≤ 2.5 V
• Hardware RESET pin
Resets internal state machine to the read mode
• Erase Suspend/Resume
Suspends the erase operation to allow a read data and/or program 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
• In accordance with CFI (Common Flash Memory Interface)

The manufacturer and device codes may also be read via the command register, for instances when the
MBM29LV017 is erased or programmed in a system without access to high voltage on the A9 pin. The command
sequence is illustrated in Table 6. (Refer to Autoselect Command section.)
Byte 0 (A0 = VIL) represents the manufacture’s code (Fujitsu = 04H) and byte 1 (A0 = VIH) represents the device
identifier code MBM29LV017 = C8H. All identifiers for manufactures and device will exhibit odd parity with DQ7
defined as the parity bit. In order to read the proper device codes when executing the autoselect, A1 must be
VIL. (See Tables 3.1 and 3.2.)
In order to determine which sectors are write protected, A1 must be at VIH while running through the sector
addresses; if the selected sector is protected, a logical ‘1’ will be output on DQ0 (DQ0 = 1).
