www.DataSheet4U.com Geode™ CS5535 I/O Companion: Multi-Function South Bridge Preliminary July 2003 Revision 0.8 Geode™ CS5535 I/O Companion Multi-Function South Bridge General Description The National Semiconductor® Geode™ CS5535 is a complete I/O companion for an integrated processor North Bridge component such as the Geode GX2 processor series. Together, the GX2 and CS5535 provide a systemlevel solution well suited for the high-performance and lowpower needs of a host of information appliances that include digital set-top boxes, personal access devices, and thin client applications. The internal architecture has been greatly simplified over previous I/O companions by use of a single, high-performance modular structure based on GeodeLink™ architecture. This architecture yields high internal speed (over 4 GB/s) data movement and extremely versatile internal power management. The GeodeLink architecture is transparent to application software. Communication with the GX2 processor is over a 33/66 MHz PCI bus. The CS5535 incorporates many I/O functions, including those found in typical SuperI/O chips, simplifying many system designs. Since the graphics subsystem is entirely contained in the GX2 processor, system interconnect is simplified. The device contains state-of-the-art power management that enables systems, especially battery powered systems, to significantly reduce power consumption. Audio is supported by an internal controller, designed to connect to multiple AC97 compatible codecs such as National’s LM4550. An IR (infrared) port supports all popular IR communication protocols. The IR port is shared with one of two industry-standard serial ports that can reach speeds of 115.2 kbps. An LPC (low pin count) port is provided to facilitate connections to a SuperI/O should additional expansion, such as a floppy drive, be necessary, and/or to an LPC ROM for the system BIOS.

Two dual-port USBs (universal serial buses, USB specification v1.1 compliant) provide four ports with both low and full-speed capabilities for Plug & Play expansion for a variety of consumer peripheral devices such as a keyboard, mouse, printer, and digital camera. A battery-backed RTC (real-time clock) keeps track of time and provides calendar functions. A suite of 82xx devices provide the legacy PC functionality required by most designs, including two PICs (programmable interrupt controllers), one PIT (programmable interval timer) with three channels, and DMA (direct memory access) functions. The CS5535 contains eight MFGPTs (multi-function general purpose timers) that can be used for a variety of functions. A number of GPIOs (general purpose input/outputs) are provided, and are assigned to system functions on power-up (i.e., LPC port); each of these may be reassigned and given different I/O characteristics such as debounce, edge-triggering, etc. State-of-the-art power management features are attained with the division of the device into two internal power domains. The GPIOs and multi-function timers are distributed into each of the two domains to allow these to act as wakeup sources for the device. In addition to full ACPI (Advanced Configuration Power Interface) compliance and support of industry-standard Wakeup and Sleep modes, the device automatically disables clocks from internal blocks when they are not being used. GeodeLink Control Processor ■ SUSP#/SUPA# handshake with power management logic provides Sleep control of all GeodeLink devices ■ System software debug support using built-in “logic analyzer” with: — 8192-bit capture memory — Capture memory can be organized wide or narrow — “Analyzer” can be connected to thousands of possible internal nodes — Synchronous operation with GX2 GeodeLink Control Processor — JTAG i.
