Overview of National* Semiconductor PC87431 Integrated
Management Controller
The National Semiconductor PC87431 integrated management controller is an Application
Specific Integrated Circuit (ASIC) with a Reduced Instruction Set Computer (RISC)-based
processor and many peripheral devices embedded into it. The National Semiconductor
PC87431 integrated management controller contains the logic needed for executing the
firmware, controlling the system, monitoring the sensors, and communicating with other systems
and devices via various external interfaces.
The following figure is a block diagram of the National Semiconductor PC87431 integrated
management controller as it is used in a server management system. The external interface
blocks to the National Semiconductor PC87431 integrated management controller are the
discrete hardware peripheral device interface modules.
