1 / 6 page October 2000 1/6 TA 235 TECHNICAL ARTICLE FIRMWARE HUB (FWH): NEW GENERATION STORAGE FOR BIOS James Lee Sandro D’Angelo STMicroelectronics Inc. STMicroelectronics Lexington, MA, USA Catania, Italy The traditional PC motherboard uses a chip-set containing two controllers, called the North Bridge and the South Bridge. Intel replaces these with the Hub. In the Hub Architecture the two controllers are connected to each other via a new Interlink dedicated bus. This is a high-speed bus that has twice the bandwidth of the PCI bus that works at 266 MBytes per second and resembles the new point-to-point channel. The new Intel PC platforms incorporate three primary components: s the Memory Control Hub (MCH), s the I/O Control Hub (ICH), s the Firmware Hub (FWH). They use the Intel Hub Protocol that allows a greater flow of information from the I/O controller to the memory controller. What is the Firmware Hub? The Firmware Hub (FWH) is a flash memory device for BIOS storage, based on Intel’s Low Pin Count (LCP) Interface Specification. It eliminates a redundant nonvolatile memory component and is a fundamental part of the new generation PC motherboards. It is the key to future security and manageability of infrastructures for the PC platform. Firmware Hub Functional Description The memory of the FWH is constructed in a uniformed matrix array of 64 KByte blocks to allow each block to be erased and reprogrammed without affecting other blocks. For functional flexibility the FWH can be operated with two different interfaces: s the Firmware Hub Interface (FWH) for embedded operation s the Address/Address Multiplexed Interface (A/ A Mux) for programming operation during manufacturing. They are selected by the setting of the Interface Configuration (IC) pin at VIL for FWH Interface mode and VIH for A/A Mux Interface mode. Figure 1.
