AMD Duron™ Processor Data Sheet 23802E—September 2000

Preliminary Information

6.3 Voltage Identification (VID[4:0])

Table 4 shows the VID[4:0] DC characteristics. For more

information, see “VID[4:0] Pins” on page 61.

6.4 Frequency Identification (FID[3:0])

Table 5 shows the FID[3:0] DC characteristics. For more

information, see “FID[3:0] Pins” on page 58.

Test

PLLTEST#, PLLMON1, PLLMON2, SCANCLK1, SCANCLK2,

SCANSHIFTEN, SCANINTEVAL, ANALOG

These pins must be pulled down to

VSS. See “General AC and DC

Characteristics” on page 27.

Miscellaneous PLLBYPASS#, DBREQ#, DBRDY, PWROK

See “General AC and DC

Characteristics” on page 27.
