50 MHz frequency added. SO8N package added, VFQFPN and
SO8W package specifications updated (see Section 12: Package
The sectors are further divided up into subsectors (see Table 4:
explanatory paragraph added. VCC supply voltage and VSS ground
added, reset timings table split into Table 23: Reset conditions and
At power-up the WIP bit is reset (see Section 7: Power-up and
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
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
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.
