5.0 REVISION HISTORY

Revision -008

To address the fact that many of the package prefix variables have changed, all package

prefix variables in this document are now indicated with an "x".

No revision history was maintained in earlier revisions of this data sheet. All errata that has been

identified to date is incorporated into this revision. The sections significantly changed since the

previous revision are:

Description

Table 4. 80960KB Pin

-005 LOCK pin description rewritten for clarity.

Description: L-Bus Signals (pg. 8)

2.3. Connection Recommenda-

tions (pg. 11)

-005

Changed suggested open-drain termination networks to reflect

more realistic operating conditions with reduction in DC power

consumption.

Figure 9. Typical Current vs.

Frequency (Hot Temp) (pg. 13)

-005 Added figure for typical power supply current at hot

temperature to aid thermal analysis.

Figure 12. Test Load Circuit for

Three-State Output Pins (pg. 14)

Figure 13. Test Load Circuit for

Open-Drain Output Pins (pg. 14)

-005 All outputs now specified with standard 50 pF test loads to

agree with actual test methodology.

2.7. DC Characteristics (pg. 15)

-005 ICC max specification reduced:

WAS:

375 mA

420 mA

480 mA

IS:

315 mA

360 mA

420 mA

AT:

16 MHz

20 MHz

25 MHz

Figures 7, 8, 9, 23, 24, 25 and 26 have also been changed

accordingly.

2.8. AC Specifications (pg. 16)

-005

25 MHz operation extended to product in PQFP package. T8

min. improved at all frequencies from 0 ns to 2 ns and T8 max.

improved from 20 ns to 18 ns.

T8H max improvement:

WAS:

31ns

Functional Waveforms

-005

Redrawn for clarity. CLK signal drawn with more likely phase

relationship to CLK2. Open-drain output signals drawn to show

correct inactive states.

-005 Deleted all references to 10 MHz. Intel no longer offers a

10 MHz 80960KB device.
