4. Memory Map
The S70GL02GT consist of uniform 64 kword (128-KB) sectors organized as shown in Table 4.
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.
5. Autoselect
Table 5 provides the device identification codes for S70GL02GT. For more information on the autoselect function, refer to the
S29GL-S datasheet (Cypress publication number 002-00247).
