S1V3S344 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. * External parts differ from S1V3034x Series devices.  Features • • • Audio playback - High-compression, high-quality audio decoder (proprietary Epson data format) - Bitrate: 40 kbps, 32 kbps, 24 kbps, 16 kbps - Sampling rate: 16 kHz Sequencer function (phrase interval setting) - Sequence setting for up to 64 phrases (unlimited combinations) - Variable phrase interval delay setting: 0 ms or 20 ms to 2,047 ms (in 1 ms steps) Voice data built-in flash memory*1 - Incorporates the following memory for voice data • 512 kbytes (approx. 4 minutes/16 kbps) • Erase/write cycles: 10,000 cycles (typ.) 1,000 cycles (min) Data retention: 10 years (min) • • • • • Host interface - Clock synchronized serial interface, supporting UART and I2C - Command control High-quality 16-bit DA converter - Sampling rate (fs): 16 kHz - Input bits: 16 bits Clock - Clock input: 32.768 kHz or 12.288 MHz - Crystal oscillator: 32.768 kHz Package - QFP-52pin (10 mm × 10 mm) 0.65 mm pin pitch Power supply voltage - 5.0 V ±0.5 V (single power supply) - 3.3 V ±0.3 V (single power supply)  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.
