AMD 10 manual Frequency Identification FID30, Vcca AC and DC Characteristics, Decoupling

31994A —1August 2004 AMD Sempron™ Processor Model 10 with 256K L2 Cache Data Sheet

7.4Frequency Identification (FID[3:0])

Table 7 shows the FID[3:0] DC characteristics. For more information, see “FID[3:0] Pins” on page 70.

Table 7. FID[3:0] DC Characteristics

Parameter	Description	Min		Max
IOL	Output Current Low	6 mA
VOH	Output High Voltage	–		2.625 V 1
			V – V	CC_CORE	≤ 1.60 V 2
			OH

Note:

1. The FID pins must not be pulled above 2.625 V, which is equal to 2.5 V plus a maximum of five percent.

2. Refer to “VCC_2.5V Generation Circuit” found in the section, “Motherboard Required Circuits,” of the AMD Athlon™ Processor- Based Motherboard Design Guide, order# 24363.

7.5VCCA AC and DC Characteristics

Table 8 shows the AC and DC characteristics for VCCA. For more information, see “VCCA Pin” on page 73.

Table 8.	VCCA AC and DC Characteristics
Symbol	Parameter	Min	Nominal	Max	Units	Notes
VVCCA	VCCA Pin Voltage	2.25	2.5	2.75	V	1
				VVCCA – VCC_CORE ≤ 1.60 V	–	2
IVCCA	VCCA Pin Current	0		50	mA/GHz	3

Notes:

1. Minimum and Maximum voltages are absolute. No transients below minimum nor above maximum voltages are permitted. 2. For more information, refer to the AMD Athlon™ Processor-Based Motherboard Design Guide, order# 24363.

3. Measured at 2.5 V.

7.6Decoupling

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.
