2 / 259 page www.national.com 2 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 such as the National PC97317 can be easily connected to the CS5530A. Features General Features Designed for use with National’s Geode GX-series processors 352 PBGA (Plastic Ball Grid Array) package 3.3V or 5.0V PCI bus compatible 5.0V tolerant on all inputs 3.3V core PCI-to-ISA Bridge PCI 2.1 compliant Supports PCI initiator-to-ISA and ISA master-to-PCI cycle translations PCI master for audio I/O and IDE controllers Subtractive agent for unclaimed transactions PCI-to-ISA interrupt mapper/translator AT Compatibility Two 8259A-equivalent interrupt controllers 8254-equivalent timer Two 8237-equivalent DMA controllers Boot ROM and keyboard chip select Extended ROMto16MB 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 GX-series processors’ 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 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 GX-series processors’ 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 |
