Ecopack® information.

10-Jul-2006

Document converted to the new ST template.

MLP package removed, SO8N package specifications updated (see

Section 12: Package mechanical).

Figure 5: SPI modes supported updated and Note 2 added. Timing line

of tSHQZ moved in Figure 29.

25-Jan-2007

50 MHz frequency added. VFQFPN package added (see Section 12:

Package mechanical).

The sectors are further divided up into subsectors (see Table 5:

M25PE20 memory organization and Table 6: M25PE10 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 and the Lock Registers are reset (see

Section 7: Power-up and power-down).

VIO max changed in Table 15: Absolute maximum ratings.

M25PE20 and M25PE10 products processed in T9HX process added to

datasheet:

–WP pin replaces TSL (T7X technology), see Section 2.7: Write Protect

(W) or Top Sector Lock (TSL)

– Read Lock Register (RDLR), Write to Lock Register (WRLR), Write

Status Register (WRSR), SubSector Erase (SSE) and Bulk Erase

(BE) instructions added for T9HX process

– subsector protection granularity removed in T9HX process, still exists

in T7X process

– Table 5: M25PE20 memory organization and Table 6: M25PE10

memory organization updated to show subsectors

– Status Register BP1, BP0 bits and SRWD bit added.

Small text changes.
