80960KA5.0 REVISION HISTORYNo revision history was maintained in earlier revisions of this data sheet. All errata that has been identified todate is incorporated into this revision. The sections significantly changed since the previous revision are:SectionLastRev.DescriptionTable 3. 80960KA Pin Description:L-Bus Signals (pg. 8)2.3. Connection Recommendations(pg. 11)Figure 9. Typical Current vs. Frequency(Hot Temp) (pg. 13)Figure 12. Test Load Circuit forThree-State Output Pins (pg. 14)Figure 13. Test Load Circuit forOpen-Drain Output Pins (pg. 14)-004 LOCK pin description rewritten for clarity.-004 Changed suggested open-drain termination networks toreflect more realistic operating conditions with reduction inDC power consumption.-004 Added figure for typical power supply current at hot temperatureto aid thermal analysis.-004 All outputs now specified with standard 50 pF test loads toagree with actual test methodology.2.7. DC Characteristics (pg. 15) -004 ICC max specification reduced:WAS: IS: AT:375 mA 315 mA 16 MHz420 mA 360 mA 20 MHz480 mA 420 mA 25 MHzFigures 7, 8, 9, 23, 24, 25 and 26 have also been changedaccordingly.2.8. AC Specifications (pg. 16) -004 25 MHz operation extended to product in PQFP package. T 8min. improved at all frequencies from 0 ns to 2 ns and T 8max. improved from 20 ns to 18 ns.T 8H max improvement:WAS: IS: AT:31ns 28ns 16 MHz26ns 23ns 20 MHz24ns 23ns 25 MHzFunctional Waveforms -004 Redrawn for clarity. CLK signal drawn with more likely phaserelationship to CLK2. Open-drain output signals drawn toshow correct inactive states.Various -004 Deleted all references to 10 MHz. Intel no longer offers a10 MHz 80960KA device.38
