(Continued)

• Compatible with JEDEC-standard commands

Uses same software commands as E2PROMs

• Compatible with JEDEC-standard world-wide pinouts

48-pin TSOP(I) (Package suffix: PFTN – Normal Bend Type, PFTR – Reversed Bend Type)

57-ball FBGA (Package suffix: PBT)

• Minimum 100,000 program/erase cycles

• High performance

80 ns maximum access time

• Sector erase architecture

Eight 4K word and sixty-three 32K word sectors in word mode

Eight 8K byte and sixty-three 64K byte 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

• Hidden ROM (Hi-ROM) region

64K byte 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.

• 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

• 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.

• In accordance with CFI (Common Flash Memory Interface)
