Revision 1.4
PC87431M/S/C
mini-Baseboard Management Controller (mBMC)
General Description
The National Semiconductor® PC87431x family of mini-
Baseboard Management Controllers (mBMC) is a light ver-
sion of the IPMI v1.5 BMC. It is targeted for a wide range of
remote-controlled platforms such as servers, workstations,
hubs and printers.
The PC87431x incorporates an embedded microcontroller,
three System Management Bus (SMBus®) interfaces, a
Chassis Management interface, Bi-color LED control, an in-
tegrated flash, Fan control, 12 ADC channels, and Digital
Input Event and General-Purpose Output pins.
The PC87431x interfaces with the host via a slave SMBus
interface; it interfaces with the LAN On Motherboard (LOM)
and with peripherals via two independent master SMBus in-
terfaces.
The PC87431x also supports distributed management archi-
tecture via the Intelligent Platform Management Bus (IPMB).
In addition, the PC87431x includes an inhibit strap to en-
able the system to work with the daughter board of an ad-
vanced BMC.
The PC87431x, like other members of National’s Advanced
I/O family, is PC01 and ACPI compliant
