TUSTIN, Calif.--(BUSINESS WIRE)--Nov. 27, 2000

TDK Semiconductor, a leader in the design and manufacture of communication semiconductors for worldwide markets, has introduced an advanced single-chip modem that combines all the controller (DTE) and data pump functions necessary to implement an intelligent V.22bis data modem.

This device, designated the 73M2909, is based on the company's implementation of the industry standard 8032 microcontroller core with a proprietary multiply accumulate (MAC) coprocessor; Sigma-Delta A/D and D/A converters; and an analog front end with integrated silicon DAA interface. All ROM and RAM necessary to operate the modem are contained on the device.

The 73M2909 is a high performance, low voltage, low power, single chip modem capable of data transmission and reception through 2400bps. The 73M2909 is intended for embedded applications and battery operation.

This device offers options for modem design ranging from a 3.3 volt low power design to a conventional 5 volt design with optional internal hybrid and fully programmable country call progress support, including CTR-21.

According to Bill Boldt, vice president of TDK Semiconductor's Embedded Systems business unit: "This is the third in our family of true 'one chip' modem solutions for embedded systems. This follows the introduction of the first `all-in-one' chip (73M2901) in 1999, followed by the release in May 2000 of our second chip (73M2902), both ideal for the set-top box market as well as many other applications.

"This family of products is backed by over 20 years of TDK Semiconductor's modem design experience and customer support. This powerful new 73M 2909 modem IC is flexible, feature rich, and easy to design-in. It offers many user friendly features such as country-specific call progress support, including CTR-21, which makes it ideal for European usage."

The 73M2909 is available in 32 pin PLCC and 44 pin TQFP packaging. Sample units and evaluation boards are available, with production planned for February 2001. Pricing for the 73M2909 is $9.89 in 25,000 unit quantities.
