W5120 is a multifunctional IC produced by Taiwan's Winbond Company. It contains a microphone top-level, automatic gain control, smoothing filter, A / D, D / A, speaker amplifier, calibration logic control point and external Serial SRAM (SSRAM) port. W5120 provides 63 voice recording sections. It can cascade multiple SSRAM, whose high level triggers the REC to work. And it provides long records without needs to reset (RESET). Quiet time compression is provided to save storage space. Besides, two overflow prevention functions are equipped (Serial SRAM is easy to overflow and so is the section index.)
