18 IR Remote Controller (REMC3)
18.1 Overview
The REMC3 circuit generates infrared remote control output signals. This circuit can also be applicable to an EL
lamp drive circuit by adding a simple external circuit.
The features of the REMC3 are listed below.
• Outputs an infrared remote control signal.
• Includes a carrier generator.
• Flexible carrier signal generation and data pulse width modulation.
• Automatic data setting function for continuous data transmission.
• Output signal inverting function supporting various formats.
• EL lamp drive waveform can be generated for an application example.
Figure 18.1.1 shows the REMC3 configuration.
