Audio advances in RL78G14 versus RL78G13 RDK

Last Updated: 06/22/2016


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


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.
