Revision A2
GENERAL 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.
FEATURES
