DC Characteristics
The DC characteristics of the AMD Athlon processor are shown
in Table 12. These values are defined at the card edge of the
AMD Athlon processor module.

1. Nominal VCC_CORE is 1.6v.
2. V
REF
:
–
V
is nominally set by a (1%) resistor divider from VCC_CORE.
–
The suggested divider resistor values are 90.9 ohms over 80.6 ohms to produce a divisor of 0.47.
–
The internal V
REF
(V
REF-INT
) is the external V
REF
scaled by 0.80 (V
REF-INT
= (V
REF
/0.80)). (Processor pin SysVrefMode = High)
–
Given: VCC_CORE = 1.6V, V
REF
= 752mV (1.6 * 0.47), V
= 940mV (752mV/0.8).
–
Peak-to-Peak AC noise on V
REF
(AC) should not exceed 2% of V
REF
(DC).
3. I
VREF
should be measured at nominal V
REF.
4. V
OL-DC-MAX,
V
OL-AC-MAX,
V
OH-DC-MIN
and V
OH-AC-MIN
are specified at T = 100
°
C and VCC_CORE = 1.4V.
5. Does not apply to V
REF
.
6. The following signals have twice the capacitance because they connect to two input pads
—
SDATAINCLK[3:0]# and SYSCLK,
SYSCLK#.
SDATAINCLK[3:0]# connects 2 byte clocks to form a word sized clock. SYSCLK connects to CLKIN/RSTCLK. SYSCLK# connects to
CLKIN#/RSTCLK#.
7.
Measured at maximum VCC_CORE = 1.70 V
—
The maximum power supply current must be taken into account when designing a
power supply.
8. A minor process update to the existing 0.25-micron technology offers improved power performance for the AMD Athlon 700-MHz
processor.
