Changes
50 MHz frequency added. SO8N package added, VFQFPN and
SO8W package specifications updated (see Section 12: Package
mechanical).
The sectors are further divided up into subsectors (see Table 4:
Memory organization). Important note on page 6 added. Figure 4:
Bus master and memory devices on the SPI bus updated and
explanatory paragraph added. VCC supply voltage and VSS ground
added. Section 4.8: Protection modes modified. Section 8: Reset
added, reset timings table split into Table 23: Reset conditions and
Table 24: Timings after a Reset Low pulse.
At power-up the WIP bit is reset (see Section 7: Power-up and
power-down).

VIO max changed in Table 13: Absolute maximum ratings. End
timing line of tSHQZ moved in Figure 28: Output timing.
Products processed in T9HX process added to datasheet:
– WP pin replaces TSL (T7X technology), see Section 2.6: Write
Protect (W) or Top Sector Lock (TSL)
– Write Status Register (WRSR) and Subsector Erase (SSE)
instructions added for T9HX process
– subsector protection granularity removed in T9HX process, still
exists in T7X process
– Table 4: Memory organization updated to show subsectors
– Status Register BP2, BP1, BP0 bits and SRWD bit added.
Small text changes.
T7X process name corrected.
Write Enable Latch (WEL) bit is reset also on completion of the
Subsector Erase, Bulk Erase, Write to Lock Register and Write
Status Register instructions (see Section 6.2: Write Disable
(WRDI)).

Address bit A20 is not Don’t care (Note 1 modified) in the Sector
Erase (SE) instruction sequence. SO8N package is only available in
products manufactured in the T9HX process.
Removed ‘low voltage’ from the title.
Table 18: DC characteristics (75 MHz operation, T9HX (0.11 µm)
process) and Table 22: AC characteristics (75 MHz operation, T9HX
(0.11µm) process) added.
