Descripción
- Voice Recorder Circuit based on C8051F411 8051 MCU. The 12-bit ADC and DAC allow for reasonable quality sound at a 8 kHz sampling rate, and the hardware Accumulation and Burst Mode features of the ADC provide for further improvements with small processing tradeoffs. The Suspend mode operating feature allows the voice recorder to sleep while idle, saving power in a similar fashion to the traditional 8051 Stop mode, but still allows the recorder to wake and respond to the user without a hardware reset
