November 2002 Revision
PC87431M/S/C mini-Baseboard Management Controller (mBMC)
National Semiconductor PC87431x family miniBaseboard Management Controllers (mBMC) light version IPMI v1.5 BMC. targeted wide range remote-controlled platforms such servers, workstations, hubs printers. PC87431x incorporates embedded microcontroller, three System Management (SMBus®) interfaces, Chassis Management interface, Bi-color control, integrated flash, control, channels, Digital Input Event General-Purpose Output pins. PC87431x interfaces with host slave SMBus interface; interfaces with Motherboard (LOM) with peripherals independent master SMBus interfaces. PC87431x also supports distributed management architecture Intelligent Platform Management (IPMB). addition, PC87431x includes inhibit strap enable system work with daughter board advanced BMC. PC87431x, like other members National's Advanced family, PC01 ACPI compliant
