Min. Delay (denoting shorter minimum valid delay AC
timing for some signal)
Kit
Supports timing for C55/C88 cache chipsets & design
P54C
1. Beginning with the P54C E-Step, standard timings have been replaced by
existing Min Delay timing.
P54CS
1. P54CS PPGA UP:No DP,No APIC,No FRC
2. Beginning with the P54C E-Step, standard timings have been replaced by
existing Min Delay timing.
P55C
1. P55C A-Step is NOT production stepping
2. A-1 step: Vcc and timing on initial samples is 2.9V +/- 0.1V
3. A-2 Step and B step: Vcc and timing on production stepping is 2.8V +/- 0.1V
