CS5536AF

Description

The AMD Geode™ CS5536 companion device is designed to work with an integrated processor North Bridge component such as the AMD Geode™ LX processor. Together, the AMD Geode LX processor and CS5536 companion device provide a system-level solution well suited for the high-performance and low-power needs of a host of embedded devices including digital set-top boxes, mobile computing devices, thin client applications, and single board computers.

The internal architecture uses 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 processor is over a 33/66 MHz PCI bus.

The CS5536 incorporates many I/O functions, including some found in typical superI/O chips, simplifying many system designs. Since the graphics subsystem is entirely contained in the AMD Geode LX processor, system interconnect is simplified. The device contains state-of-theart 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. 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.
