= 2.7–3.6V (program, erase, read)

– V

CCQ

= 1.65–3.6V (I/O buffers)

• Asynchronous random or page read

– Page size: 8 words or 16 bytes

– Page access: 25ns

– Random access: 60ns (BGA); 70ns (TSOP)

• Buffer program: 256-word MAX program buffer

• Program time

– 0.56µs per byte (1.8 MB/s TYP when using 256-

word buffer size in buffer program without V

PPH

)

– 0.31µs per byte (3.2 MB/s TYP when using 256-

word buffer size in buffer program with V

PPH

)

• Memory organization

– 32Mb: 64 main blocks, 64KB each, or eight 8KB

boot blocks (top or bottom) and 63 main blocks,

64KB each

– 64Mb: 128 main blocks, 64KB each, or eight 8KB

boot blocks (top or bottom) and 127 main blocks,

64 KB each

– 128Mb: 128 main blocks, 128KB each

• Program/erase controller

– Embedded byte/word program algorithms

• Program/erase suspend and resume capability

– READ operation on any block during a PRO-

GRAM SUSPEND operation

– READ or PROGRAM operation on one block dur-

ing an ERASE SUSPEND operation on another

block

• BLANK CHECK operation to verify an erased block

• Unlock bypass, block erase, chip erase, and write to

buffer capability

– Fast buffered/batch programming

– Fast block and chip erase

• V

/WP# pin protection

– V

PPH

voltage on V

to accelerate programming

performance

– Protects highest/lowest block (H/L uniform) or

top/bottom two blocks (T/B boot)

• Software protection

– Volatile protection

– Nonvolatile protection

– Password protection

– Password access

• Extended memory block

– 128-word (256-byte) block for permanent secure

identification

– Program or lock implemented at the factory or by

the customer

• Low-power consumption: Standby mode
