1 / 102 page  © 2000 National Semiconductor Corporation www.national.com General Description The National Semiconductor® Geode™ CS4210 is a PCI- based IEEE 1394 OHCI (Open Host Controller Interface) controller. The CS4210 provides an implementation of the IEEE 1394 Link Layer functionality according to the pro- gramming model defined by 1394 OHCI Specification Ver- sion 1.0. It supports high speed serial communication up to 400 Mbits per second. The CS4210 is an implementation of the link layer protocol of the IEEE 1394 high speed serial bus, with additional fea- tures to support the transaction and bus management lay- ers. The CS4210 also includes DMA engines for high speed performance data transfer and a host PCI bus inter- face. Perfect for use in PC, set-top box, thin client, and WebPAD™ system applications. The CS4210 supports two types of data transfers: asyn- chronous and isochronous. The CS4210 provides an external IEEE 1394 physical layer device interface. The CS4210’s physical layer interface (PHY-Link) is compatible with the Geode™ CS4103 and other IEEE 1394 physical layer devices. Features Supports 100, 200, and 400 Mbit/sec data transfer rates Compliant with 1394 OHCI Specification Version 1.0 Compatible interface with the Geode CS4103 IEEE P1394a Physical Layer (PHY) device and other IEEE 1394-1995 version and P1394a Draft 2.0 Physical Layer devices Eight isochronous transmit contexts Eight isochronous receive contexts Capable of reading a 128-byte descriptor in one burst 128 byte, zero wait state bursting Dynamically re-prioritize services 2 KB of isochronous transmit FIFO 2 KB of asynchronous transmit FIFO 4 KB of receiver FIFO Per-packet FIFO thresholding Four concurrent posted writes Eight pending physical responses National specific configuration registers I2C interface support for an optional serial EEPROM Accepts and generates external 8 kHz reference clock 5V tolerant PCI rev 2.1 I/O interface 0.25µ CMOS 100-pin LQFP (Low-profile Quad Flat Pack) package NAND tree for test purposes System Block Diagram Geode™ CS4210 IEEE 1394 OHCI Controller Geode™ CS4103 P1394a Physical Layer EEPROM I2C Interface PCI Interface PHY-Link Interface PCI Bus IEEE 1394 Cable Connectors July 2000 Geode™ CS4210 IEEE 1394 OHCI Controller National Semiconductor is a registered trademark of National Semiconductor Corporation.
