9.17 System Management Bus (SMBus 2.0)

The Intel 3420 contains an SMBus Host interface that allows the processor to communicate with SMBus slaves.

This interface is compatible with most I2C devices. Special I2C commands are implemented.

The Intel 3420’s SMBus host controller provides a mechanism for the processor to initiate communications

with SMBus peripherals (slaves). Also, the Intel 3420 supports slave functionality, including the Host Notify

protocol. Hence, the host controller supports eight command protocols of the SMBus interface (see System

Management Bus

(SMBus) Specification, Version 2.0): Quick Command, Send Byte, Receive Byte, Write Byte/Word, Read

Byte/Word, Process Call, Block Read/Write, and Host Notify.

Intel 3420’s SMBus also implements hardware-based Packet Error Checking for data robustness and the

Address Resolution Protocol (ARP) to dynamically provide address to all SMBus devices.

9.18 Intel Anti-Theft Technology

The Intel 3420 introduces a new hardware-based security technology which encrypts data stored on any

SATA compliant HDD in AHCI Mode. This feature gives the end-user the ability to restrict access to HDD data

by unknown parties. Intel

Anti-Theft Technology can be used alone or can be combined with software

encryption applications to add protection against data theft.

Intel

Anti-Theft Technology functionality requires a correctly configured system, including an appropriate

processor, Intel Management Engine firmware, and system BIOS support.

9.19 Intel Virtualization Technology for Directed I/O

The Intel 3420 provides hardware support for implementation of Intel

Virtualization Technology with

Directed I/O (Intel

VT-d). Intel VT-d Technology consists of technology components that support the

virtualization of platforms based on Intel

Architecture Processors. Intel VT-d Technology enables multiple

operating systems and applications to run in independent partitions. A partition behaves like a virtual

machine (VM) and provides isolation and protection across partitions. Each partition is allocated its own

subset of host physical memory.

9.20 JTAG Boundary-Scan

Intel 3420 adds the industry standard JTAG interface and enables Boundary-Scan in place of the XOR chains

used in previous generations of the Intel 3420. Boundary-Scan can be used to ensure device connectivity

during the board manufacturing process. The JTAG interface allows system manufacturers to improve

efficiency by using industry available tools to test the Intel 3420 on an assembled board. Since JTAG is a

serial interface, it eliminates the need to create probe points for every pin in an XOR chain. This eases pin

breakout and trace routing and simplifies the interface between the system and a bed-of-nails tester.
