Description

The 73M2901/3.3V 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 TDK Semiconductor' s implementation of the ustrstandard 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 ice. Additionally, the 73M2901/3.3V provides an on-chip oscillator and Hybrid driver.

The 73M2901/3.3V is a high performance, low voltage, low power, single chip modem capable of data transmission and reception through 2400bps.The 73M2901/3.3V is intended for embedded applications and battery operation. This evice
offers low power 3.3 volt design with optional internal hybrid and country specific call progress support.
