The National Semiconductor PC87427 is targeted for a wide range of servers, workstations and high-end desktops that use the Low Pin Count (LPC) bus for the host interface and an SMBus® interface for either a Baseboard Management Controller (BMC) or mini-BMC (mBMC), both of which are optional.
For LPC and SMBus access, the PC87427 features a fast X-Bus, over which boot flash and I/O devices can be accessed. The PC87427 supports X-Bus address line forcing (to 0 or 1) to create memory windows for BIOS data storage. When VSB exists, the BMC or mBMC can access the PC87427 and its fast X-Bus via SMBus. The SMBus also controls serial port float, RTC access, and serial port interconnection (snoop and take-over modes). In addition, the PC87427 provides routing of up to two selected LPC I/O port transactions to the GPIO Extension Port.
The PC87427 provides a VSB-powered high-frequency clock for on-chip peripherals; it also provides a configurable highfrequency clock for other VSB-powered platform components. The PC87427 supports SensorPath health monitor interface to LMPCxx sensors, fan monitoring and control, and a chassis intrusion detector. The System Wake-Up Control (SWC) module supports flexible wake-up and power-off request mechanisms for all platforms (i.e., with or without BMC/mBMC).
The PC87427 supports both I/O and memory mapping of module registers and enables building legacy-free systems.
The PC87427 also incorporates a Floppy Disk Controller (FDC), two serial ports (UARTs), a Keyboard and Mouse Controller (KBC), General-Purpose Input/Output (GPIO), GPIO extension for additional off-chip GPIO ports, and an interrupt serializer for parallel IRQs.
