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
1. Typical program and erase times assume the following conditions: 25°C, 3.6 V V
CC
, 10,000 cycles, checkerboard pattern.
2. Under worst case conditions of -40°C, V
CC
= 3.0 V, 100,000 cycles.
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.
