General Description

The 73M2901C/5V is a single-chip modem that combines all the controller (DTE) and data pump functions necessary to implement an intelligent V.22bis data modem. This device is based on Teridian Semiconductor's implementation of the industry standard 8032 microcontroller core with a proprietary multiply and accumulate (MAC) coprocessor; Sigma-Delta A/D and D/A converters; and an analog front end. The ROM and RAM necessary to operate the modem are contained on the device. Additionally, the 73M2901C/5V provides an on-chip oscillator and Hybrid driver.
