Audio advances in RL78G14 versus RL78G13 RDK

Last Updated: 06/22/2016

Question:

What audio feature improvements have been made in the RL78G14 RDK compared to the RL78G13 RDK?

Answer:

We have added DAC capability to the standard audio PWM output that was present in the RL78G13 RDK. By selecting the jumpers JP1/JP2, the RL78G14 is able to generate 2 audio playback channels to the headphone/speaker jack (J12). The audio quality is limited to the DAC capabilities which is 8-bit resolution, good enough for speech and alarm synthesis.
