AMD Opteron
Processor Data Sheet
23932 Rev 3.00 April 2003
Notes:
1. See the
AMD Opteron
Processor Motherboard Design Guide
, order# 25180, for proper resistor values.
2. Input pins of the same type may be pulled high or low through a shared resistor provided that VIL Max and VIH Min
specifications are not exceeded for those pin types.
7.4.4
Thermal Diode Specifications
Notes:
1. The sourcing current should always be used in forward bias.
2. Characterized at 95
o
C with a forward bias current pair of 10 and 100
μ
A. The ideality factor limits correspond to the
diode offset limits.
3. Temperature offset is unique for each processor. The diode offset value is found in the Thermtrip Status Register
discussed in the
BIOS and Kernel Developer
’
s Guide for the AMD Athlon
64 and AMD Opteron
Processors,
order# 26094. This diode offset supports temperature sensors using two or more sourcing currents only. Single-
sourcing current implementations are not supported by AMD.
4. The temperature offset is set based on a sourcing current pair of 10 and 100
μ
A and an ideality factor of 1.008. The
diode offset should be subtracted from the temperature sensor reading. If the temperature sensor has an ideality factor
different from 1.008, an additional offset is needed. Contact your temperature sensor vendor about whether an
additional offset is needed.
