PCIE-8120 Hardware Description
PCIE-8120 Installation and Use (6806800R89C) 70
The CPLD is connected as a slave device on the PCI Express SMBus.
ID PROM (Optional)
A serial EEPROM is available on the PVT_I2C bus for the purpose of storing manufacturer or user
data specific to the card. This ID PROM device is optional and may not be present on specific
variants of the card.
 M24C04 Device
 4 kbits density
 I2C address: 0xA0
Temperature Sensors
There are two temperature sensors on the PVT_I2C bus for monitoring the temperature on the
card and the thermal behavior of the system. One sensor is placed on the mounting bracket
side which is considered as the air outlet side. The other sensor is placed on the card retainer
side which is considered as the air inlet side (see
Figure "Temperature Sensor Location" on page
72 .)
