DESCRIPTION

The 73M2901CE low speed modem integrates a data pump, controller, and analog front end in a 3.3 V device with a powerful AT command host interface. The modem reduces external component count/cost by incorporating many features like parallel phone detect, Line-In-Use and Ring detection in software without requiring additional omponents.
