Geode™ CS5535 I/O Companion

Multi-Function South Bridge

General Description

The National Semiconductor^®Geode™ CS5535 is a com-

plete I/O companion for an integrated processor North

Bridge component such as the Geode GX2 processor

series. Together, the GX2 and CS5535 provide a system-

level solution well suited for the high-performance and low-

power needs of a host of information appliances that

include digital set-top boxes, personal access devices, and

thin client applications.

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 man-

agement 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 popu-

lar 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 pro-

vided to facilitate connections to a SuperI/O should addi-

tional expansion, such as a floppy drive, be necessary,

and/or to an LPC ROM for the system BIOS.

The internal architecture has been greatly simplified over

previous I/O companions by use of a single, high-perfor-

mance modular structure based on GeodeLink™ architec-

ture. This architecture yields high internal speed (over 4

GB/s) data movement and extremely versatile internal

power management. The GeodeLink architecture is trans-

parent to application software. Communication with the

GX2 processor is over a 33/66 MHz PCI bus.
