The National Semiconductor PC87431M mini-Baseboard Management Controller (mBMC) is an
Application Specific Integrated Circuit (ASIC) with a Reduced Instruction Set Computer (RISC)-
based processor and many peripheral devices embedded into it. It is targeted for a wide range
of remote-controlled platforms, such as servers, workstations, hubs, and printers.
The mBMC contains the logic needed for executing the firmware, controlling the system,
monitoring sensors, and communicating with other systems and devices via various external
interfaces.
The following figure illustrates the block diagram of the mBMC, as it is used in a server
management system. The external interface blocks to the mBMC are the discrete hardware
peripheral device interface modules shown as blocks outside of the mBMC ASIC.
