Revision 4.1

Two bus mastering IDE controllers are included for sup-

port of up to four ATA-compliant devices. A two-port Uni-

versal Serial Bus (USB) provides high speed, Plug & Play

expansion for a variety of consumer peripheral devices

such as a keyboard, mouse, printer, and digital cameras.

If additional functions are required, such as real-time

clock, floppy disk, PS2 keyboard, and PS2 mouse, a

SuperI/O (e.g., National PC97317) can be easily con-

nected to the CS5530.

Bus Mastering IDE Controllers

Two controllers with support for up to four IDE devices

Independent timing for master and slave devices for

both channels

PCI bus master burst reads and writes

Ultra DMA/33 (ATA-4) support

Multiword DMA support

Programmed I/O (PIO) Modes 0-4 support

Power Management

Intelligent system controller supports multiple power

management standards:

— Full ACPI and Legacy (APM) support

— Directly manages all GXLV and GXm processor

power states (including automatic Suspend modula-

tion for optimal performance/thermal balancing)

I/O traps and idle timers for peripheral power

management

Up to eight GPIOs for system control:

— All eight are configurable as external wakeup events

Dedicated inputs for keyboard and mouse wakeup

events

XpressAUDIO

Provides "back-end" hardware support via six buffered

PCI bus masters

AC97 codec interface:

— Specification Revision 1.3, 2.0, and 2.1 compliant

interface. Note that the codec (e.g., LM4548) must

have SRC (sample rate conversion) support

Display Subsystem Extensions

Complements the GXLV and GXm processor’s

graphics and video capabilities:

— Three independent line buffers for accelerating

video data streams

— Handles asynchronous video and graphics data

streams concurrently from the processor

— YUV to RGB conversion hardware

— Arbitrary X & Y interpolative scaling

— Color keying for graphics/video overlay

VDACs/ Displayinterface:

— Three integrated DACs

— Gamma RAM:

– Provides gamma correction for graphics data

streams

– Provides brightness/contrast correction for video

data streams

— Integrated DOT clock generator

— Digital RGB interface drives TFT panels or standard

NTSC/PAL encoders

Universal Serial Bus

Two independent USB interfaces:

— Open Host Controller Interface (OpenHCI)

specification compliant

— Second generation proven core design
