AMD Geode™ CS5530A Companion Device

Revision 1.1

Two bus mastering IDE controllers are included for support

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

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

sion for a variety of consumer peripheral devices such as a

keyboard, mouse, printer, and digital camera. If additional

functions are required like real-time clock, floppy disk, PS2

keyboard, and PS2 mouse, a SuperI/O device can be eas-

ily connected to the CS5530A.

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 GX1 processor’s power states

(including automatic Suspend modulation 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™ Subsystem

■ 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 must have SRC

(sample rate conversion) support

Display Subsystem Extensions

■ Complements the GX1 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 / Display interface:

— 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

— Up to 1280x1024 @ 85 Hz

Universal Serial Bus

■ Two independent USB interfaces:

— Open Host Controller Interface (OpenHCI)

specification compliant

— Second generation proven core design
