DESCRIPTION

The MBM29PDS322TE/BE is 32M-bit, 1.8 V-only Flash memory organized as 2M words of 16 bits each. The device is offered in 63-ball FBGA package. This device is designed to be programmed in system with 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 reprogrammed in standard EPROM programmers.

FEATURES

• 0.23 µm Process Technology

• Simultaneous Read/Write operations (Dual Bank)

Host system can program or erase in one bank, and then read immediately and simultaneously from the other bank with zero latency between read and write operations.

Read-while-erase

Read-while-program

• High performance Page Mode

45 ns maximum page access time (100 ns random access time) 4 words Page Size

• Single 1.8 V read, program, and erase

Minimized system level power requirements

• Compatible with JEDEC-standard commands Use the same software commands as E2PROMs.

• Compatible with JEDEC-standard world-wide pinouts

63-ball FBGA (Package suffix: PBT)

• Minimum 100,000 program/erase cycles

• Sector erase architecture

Eight 4 Kword and sixty-three 32 Kword sectors in word 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

64 Kbyte 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.

• 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.

• 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 RESET pin.
