Description

-001

Initial release of datasheet.

-002

Status changed from Product Preview to Preliminary

28F400CV/CE/BE references and information added throughout.

2.7V CE/BE specs added throughout.

The following sections have been changed or rewritten: 1.1, 3.0, 3.2.1, 3.2.2, 3.3.1,

3.3.1.1, 3.3.2, 3.3.2.1, 3.3.3, 3.3.4, 3.6.2.

Note 2 added to Figure 3 to clarify 28F008B pinout vs. 28F008SA.

Sentence about program and erase WSM timeout deleted from Section 3.3.3, 3.3.4.

Erroneous arrows leading out of error states deleted from flowcharts in Figs. 9, 10.

Sections 5.1, 6.1 changed to “Applying VCC Voltages.” These sections completely

changed to clarify VCC ramp requirements.

IPPD 3.3V Commercial spec changed from 10 to 5

µA.

Capacitance tables added after commercial and extended DC Characteristics tables.

Test and slew rate notes added to Figs. 12, 13, 19, 20, 21.

Test configuration drawings (Fig. 14, 22) consolidated into one, with component

values in table. (Component values also rounded off).

tELFL, tELFH, tAVFL changed from 7 to 5 ns for 3.3V BV-60 commercial and 3.3V

TBV-80 extended, 10 to 5 ns for 3.3V BV-80 and BV-120 commercial.

tWHAX and tEHAX changed from 10 to 0 ns.

tPHWL changed from 1000 ns to 800 ns for 3.3V BV-80, BV-120 commercial.

tPHEL changed from 1000 ns to 800 ns for 3.3V BV-60, BV-80, and BV-120 commercial.

-003

28F400BE row removed from Table 1

Applying VCC voltages (Sections 5.1 and 6.1) rewritten for clarity.

Minor cosmetic changes/edits.

-004

Corrections: Spec typographical error “tQWL” corrected to read “tQVVL.”

Intel386™ EX Microprocessor block diagram updated because latest Intel386 CPU

specs require less glue logic.

Spec tELFL and tELFH changed from 5 ns (max) to 0 ns (min).

New specs tPLPH and tPLQX added from Specification Update document (297595).

Specs tEHQZ and tGHQZ improved on most voltage/speed combinations.

-005

Correction: Appendix A, Ordering information fixed order numbers from TE27F400BVT80

to TE28F400BVT80 and TE27F400BVB80 to TE28F400BVB80.
