Description

Table 4. 80960KB Pin Description:

L-Bus Signals (pg. 8)

-005

LOCK pin description rewritten for clarity.

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. Fre-

quency (Hot Temp) (pg. 13)

-005

Added figure for typical power supply current at hot tempera-

ture 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:

IS:

31ns

28ns

26ns

23ns

24ns

23ns

AT:

16 MHz

20 MHz

25 MHz

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.

Various

-005

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

10 MHz 80960KB device.
