Combining all the controller and data pump functions necessary to implement an intelligent V.22bis data modem, the 73M2909 is an advanced single-chip modem capable of data transmission and reception through 2,400 b/s. The device is based on the company's implementation of the industry standard 8032 microcontroller core with a proprietary multiply accumulate co-processor, sigma-delta A/D and D/A converters, and an analog front end with integrated silicon DAA interface. Intended for embedded applications, the chip offers several options for modem design. In a 32-pin PLCC or 44-pin TQFP, the chip is priced at $9.89 each/25,000.
