ISD9160Fl micro audio chip

Special microcontroller for recording and processing audio data Nuvoton production. This microcontroller uses ARM Cortex-M0 core with 145kB APROM and 12kBSRAM. The advantages of this controller is to have many features that are devoted to process signals, such as: DAC, DPWM, PGA, PDMA, and pin for a digital microphone. ADC on this controller is equipped with features Sigma-Delta with 92dB SNR (Signal to Noise Ratio). Plus it features a Programmable Gain Amplifier (PGA) with a maximum gain of up to 61dB, making the processed audio signal is able to be directly connected to the microphone or speaker.
