3. Memory Map

The S70GL02GP consist of uniform 64 Kword (128 Kb) sectors organized as shown in Table 2.

Note

This table has been condensed to show sector-related information for an entire device on a single page. Sectors and their address ranges that are not explicitly listed

(such as SA001-SA2046) have sector starting and ending addresses that form the same pattern as all other sectors of that size. For example, all 128 Kb sectors have the

pattern xxx0000h-xxxFFFFh.

4. Autoselect

Table 3 provides the device identification codes for the S70GL02GP. For more information on the autoselect function, refer to the

S29GL01P datasheet.

5. Erase And Programming Performance

Notes

3. In the pre-programming step of the Embedded Erase algorithm, all bits are programmed to 00h before erasure.

4. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command.
