2. Kit Overview

Voice applications require a microcontroller to sample the audio channel, compress and decompress the signal,

store and retrieve the samples, and interpret user input. With its available feature set (12-bit ADC, 12-bit DAC,

50 MIPS peak CPU, low-power SUSPEND mode, and extremely small size in a 28-pin QFN package), the

C8051F411-GM is uniquely suited for this purpose. This reference design illustrates how to use a C8051F411-GM

for voice applications.
