73M2901CE開發(fā)板套件編程器的評估演示板及套件規(guī)格書PDF中文資料

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.
