PC87427 - Server I/O

General Description

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.

Key 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.
