Technical Product Specification

Intel® Server Board S2600IP and Intel® Workstation Board W2600CR TPS Functional Architecture
Revision 1.4 Intel order number G34153-004 39
3.3.11 Advanced Programmable Interrupt Controller (APIC)
In addition to the standard ISA compatible Programmable Interrupt controller (PIC) described in
the previous section, the Intel
®
C602 Chipset incorporates the Advanced Programmable
Interrupt Controller (APIC).
3.3.12 Universal Serial Bus (USB) Controllers
The Intel
®
C602 Chipset has up to two Enhanced Host Controller Interface (EHCI) host
controllers that support USB high-speed signaling. High-speed USB 2.0 allows data transfers up
to 480 Mb/s which is 40 times faster than full-speed USB. The Intel
®
C602 Chipset supports up
to fourteen USB 2.0 ports. All fourteen ports are high-speed, full-speed, and low-speed capable.
3.3.13 Gigabit Ethernet Controller
The Gigabit Ethernet Controller provides a system interface using a PCI function. The controller
provides a full memory-mapped or IO mapped interface along with a 64 bit address master
support for systems using more than 4 GB of physical memory and DMA (Direct Memory
Addressing) mechanisms for high performance data transfers. Its bus master capabilities enable
the component to process high-level commands and perform multiple operations; this lowers
processor utilization by off-loading communication tasks from the processor. Two large
configurable transmit and receive FIFOs (up to 20 KB each) help prevent data underruns and
overruns while waiting for bus accesses. This enables the integrated LAN controller to transmit
data with minimum inter-frame spacing (IFS).
The LAN controller can operate at multiple speeds (10/100/1000 MB/s) and in either full duplex
or half duplex mode. In full duplex mode the LAN controller adheres with the IEEE 802.3x Flow
Control Specification. Half duplex performance is enhanced by a proprietary collision reduction
mechanism.
3.3.14 RTC
The Intel
®
C602 Chipset contains a real-time clock with 256 bytes of battery-backed RAM. The
real-time clock performs two key functions: keeping track of the time of day and storing system
data. The RTC operates on a 32.768 KHz crystal and a 3.0 V battery.
3.3.15 GPIO
Various general purpose inputs and outputs are provided for custom system design. The
number of inputs and outputs varies depending on the Intel
®
C602 Chipset configuration.
3.3.16 Enhanced Power Management
The power management functions of Intel
®
C602 Chipset include enhanced clock control and
various low-power (suspend) states (for example, Suspend-to-RAM and Suspend-to-Disk). A
hardware-based thermal management circuit permits software-independent entrance to low-
power states. The Intel
®
C602 Chipset contains full support for the Advanced Configuration and
Power Interface (ACPI) Specification, Revision 4.0a.
3.3.17 Manageability
In addition to Intel AMT the Intel
®
C602 Chipset integrates several functions designed to
manage the system and lower the total cost of ownership (TCO) of the system. These system
management functions are designed to report errors, diagnose the system, and recover from
system lockups without the aid of an external microcontroller.
