Abstract
A semiconductor device includes a single substrate including circuitry to implement a processor, a memory coupled to the processor, an audio interface module configured to provide data in pulse-code modulation (PCM) format having a first signal to noise ratio (SNR), and a medium quality speaker module configured to receive the PCM data, convert the data from the PCM format to a pulse-width modulation (PWM) format independently of the processor, and provide the data in the PWM format having a second SNR to at least one general purpose input-output pin on the substrate, the first SNR is greater than the second SNR.
