AUSTIN, Tex. – Oct. 30, 2000 – Cirrus Logic, Inc. (NASDAQ:CRUS), the leader in embedded Ethernet for residential gateways, today announced the CS89712 System On Chip (SOC) for Internet communications devices. The CS89712 is the industry’s first device to combine a low power, high performance 74MHz ARM720TDMI Core with 10Mbps Ethernet connectivity (MAC and PHY) and a wide array of peripherals.
The CS89712 simplifies the design and reduces the total system cost of Internet communication systems including H.323 and SIP based VoIP telephones and other communications appliances. The built-in Memory Management Unit (MMU), 8K-bytes of cache, and 48K of SRAM make the CS89712 ideal for customers wishing to incorporate Open Source operating systems, such as Linux, or the commercially available single source solution comprised of the real time operating system ThreadX from Express Logic and debugging tools from Green Hills Software. Tool support is also available from ARM, Ltd. and others.
“Now that the bandwidth problem is being addressed for Internet users around the world, the market for communications devices that utilize that bandwidth is beginning to grow rapidly,” said Clark Jernigan, vice president and general manager of Cirrus Logic’s Communications Division.
“We are seeing increased customer demand for open source operating systems and applications such as embedded Linux that allow customers to get to market quickly and with a lower total system cost,” added Jeff Luftig, product marketing manager.
Feature Rich Device
Minimizing the need for external logic in system implementations, the CS89712 incorporates the following suite of system peripherals:
With its rich set of built-in peripherals, the CS89712 requires few additional components to provide a complete communications system. To aid developers with product design, the chip also offers embedded in-circuit emulation (ICE) and silicon debug support via a JTAG port.
Cirrus Logic is the leading provider of Ethernet solutions for the embedded marketplace. Its Crystal Ethernet controllers are used in products that provide high-speed access to the Internet, such as cable modems, ADSL modems, and cable set-top boxes, as well as VoIP telephones. The CS89712 extends Cirrus Logic’s portfolio in communications processors to support the next generation of Internet communications appliances that take advantage of the broadband access now available.
Price and Availability
The CS89712 is available in a 256-lead PBGA package and is priced at $27.00 in 10k quantities. Samples and Evaluation boards are available in December.
