General Description

The Mosel SW003 is a monolithic CMOS LSI intelligent chip that is dedicated for clock/watch application with time announcing & alarm warning. 10 sentences are built-in for report and adjusting time and alarm. 3 1/2 digits LCD with 3 information flags are interfaced. With Mosel Editing system, every human language can be defined by user when manuafacturing.

Features

■ Single power can operate at 3.0V or 4.5V (LCD dependent)
