System Management Controller
The system management controller is implemented with an Actel FPGA AFS600-256, which is a flash
memory based mixed signal FPGA (see
Figure 6
). This FPGA has an embedded processor and is
mainly powered by 3.3V_MP from an AMC finger connector since the system controller must be
functioning whenever 3.3V_MP is available.
