Bus Number Technology Type Device Count Comment
0 SMBus (primary) JIDA 3
8.3.1 Bus Number 0 (JIDA/Generic)
Through this bus several devices can be handled.
This bus allows access to the JIDA EEPROM in which KONTRON specific manufacturing parameters are
stored. A damage of these parameters leads to a loss of warranty. Due to this a write cycle may only be per-
formed above a defined address.
Device Address Size Read Access Write Access
Temp. sensor 98h 256 Bytes Yes Yes
SPD EEPROM A0h 256 Bytes Yes No, forbidden
JIDA EEPROM A8h 512 Bytes Yes
Yes, between
28h to 1C8h

8.5.1 Temperature
The term On-Chip diode designates the chip temperature of the temperature sensor (with no dependence to
the CPU temperature).
Sensor Number Abs. Thermal Limit
On-Chip diode 0 0 to +80 0 C
CPU diode 1 0 to +100 0 C
