E82802AC

Product Summary

The Intel 82802 Firmware Hub (FWH) discrete component is compatible with several Intel chipset platforms and a variety of applications. The device operates under the LPC/FWH interface/protocol. The hardware features of this device include a Random Number Generator (RNG), five General-Purpose Inputs (GPIs), register-based block locking, and hardware-based locking. This combination of logic features and non-volatile memory enables better protection for the storage and update of platform code and data, adds platform flexibility through additional GPIs, and allows for quicker introduction of new security/manageability features into current and future platforms. The platform RNG, accessed through the Intel Security Driver and third-party software, enables security features for the PC platform.

Parametrics

Absolute maximum ratings:(1)case tempreture under blas: -10鈩?to 85鈩? (2)storage tempreture: -65鈩?to 125鈩? (3)supply voltage with respect to vss: -0.2V to 4.1V; (4)voltage on any pin (except Vpp): -0.5 to 14V; (5)Output short circuit current: 100mA.

Features

Features: (1)Enables security-enhanced platform infrastructure; facilitates option to remove ISA; (2)5-Signal communication interface supporting byte-at-a-time reads and writes; (3)Register-based read and write protection for each code/data storage block ; (4)Hardware write protect pins for the top boot block and the remaining code/data storage blocks ; (5)5 Additional GPIs for platform design flexibility Contains a hardware Random Number Generator (RNG) for enhancing platform security; (6)Integrated Command User Interface (CUI) for requesting access to locking, programming, and erasing options.
