4.4.1 Temperature Sensors
The on board temperature sensors are implemented using National LM75 digital temperature
sensors. The following table provides the upper non-critical, critical and non-recoverable
temperature thresholds for each of the onboard temperature sensors.
4.5 FPGA
A Xilinx XC3S400A Spartan 3A family FPGA is used on the board to provide a combination of
glue logic functions and telecom clock support functions. These functions include the
following:

Local Bus Interface

Local Bus Decoder

Low pin count interface between Host and IPMC

Interrupt Routing Unit

Reset Controller

Local Bus to SPI Interface

Telecom Clocking Support
