Description

The W51300 is a voice recorder IC which contains A/D and D/A converters to digitize and reproduce voice signals. An anti-alias/smoothing filter, AGC circuit, MIC preamplifier, and speaker power amplifier are used to smooth the input voice and set the output voice to a certain volume while minimizing the number of extra components needed. The recording time depends on the size of the external memory.

The external memory is a nonvolatile flash EPROM that stores the voice data while power is switched off. This external memory provides a great advantage in cartridge or greeting card applications. A maximum of 16 Mbit of memory can be cascaded. In addition, the W51300's flexible segmentation, selective recording/erasing, forward and backward move functions, and MCU interface provide flexibility to meet the needs of a wide variety of applications.
