Voice Guidance LSI

 Overview

The S1V3S344 is an LSI incorporating built-in flash memory for voice data and featuring pin compatibility

with existing S1V3034x Series devices*. It features high-compression, high-quality audio decoding

functions, built-in voice data flash memory, and a DA converter, making it ideal for use in voice guidance

products. The voice data creation tool for EPSON voice guidance LSI allows easy creation of high-quality

voice data without the need for studio recording. All functions are controlled by commands via a serial

interface for easy addition to any existing system incorporating a host.

The S1V3S344 will help evaluate voice output and help users reduce time-to-market for products

incorporating built-in voice guidance functions.

 Features



 Standard application system

The S1V3S344 standard application system is configured as shown in the diagram below. The S1V3S344

is command-controlled by the host using a messaging protocol via the serial interface.

Controlled by commands sent from the host via the serial interface after power-on resetting, the S1V3S344

outputs voice audio while internally decoding and processing internal or streamed (via host command

transfer) compressed audio data.
