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.
