C-Devices
The
NAT-AMC-ZYNQUP-FMC
implements an IPMB interface consisting of an IPMI-µC
(ATXMega128) and a couple of I
2
C devices connected via I²C.
The following figure shows the architecture in detail.

The external channel of the temperature sensor monitors the FPGA temperature, the internal
channel measures the local PCB temperature.
The IPMI controller also manages the geographical address as requested by the AMC
specification.
