AMD Preliminary Information

7.4 Frequency Identification (FID[3:0])

Table 7 shows the FID[3:0] DC characteristics. For more

information, see “FID[3:0] Pins” on page 70.

7.5 VCCA AC and DC Characteristics

Table 8 shows the AC and DC characteristics for VCCA. For

more information, see “VCCA Pin” on page 73.

7.6 Decoupling

See the AMD Athlon™ Processor-Based Motherboard Design

Guide, order# 24363, or contact your local AMD office for

information about the decoupling required on the motherboard

for use with the AMD Sempron processor model 10.
