MBM29DL32XTE/BE80/90
■ FEATURES
• 0.23 µm Process Technology
• Simultaneous Read/Write operations (dual bank)
Multiple devices available with different bank sizes (Refer to “MBM29DL32XTE/BE Device Bank Divisions” in
“■ FEATURES”)
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 (1) (Package suffix : TN − Normal Bend Type, TR − Reversed Bend Type)
63-ball FBGA (Package suffix : PBT)
• Minimum 100,000 program/erase cycles
• High performance
80 ns maximum access time
• Sector erase architecture
Eight 4 Kword and sixty-three 32 Kword sectors in word mode
Eight 8 Kbyte and sixty-three 64 Kbyte 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
• HiddenROM region
64 Kbyte of HiddenROM, accessible through a new “HiddenROM 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 group protection/unprotection status
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
• 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 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
