? 8,388,608 x 8 / 4,194,304 x 16 switchable

? Sector structure

- 8KB (4KW) x 8 and 64KB(32KW) x 127

? Sector Protection/Chip Unprotect

- Provides sector group protect function to prevent

program or erase operation in the protected sector

group

- Provides chip unprotect function to allow code

changes

- Provides temporary sector group unprotect function

for code changes in previously protected sector groups

? Secured Silicon Sector

- Provides a 128-word area for code or data that can

be permanently protected.

SOFTWARE FEATURES

? Support Common Flash Interface (CFI)

- Flash device parameters stored on the device and

provide the host system to access.

? Erase Suspend/ Erase Resume

- Suspends sector erase operation to read data from

or program data to another sector which is not being

erased

? Status Reply

- Data polling & Toggle bits provide detection of program and erase operation completion

HARDWARE FEATURES
