S1V30120 Hardware Specification (Rev. 1.2) EPSON 1
1. Outline
The S1V30120 is a Speech Synthesis IC that provides a cost effective solution for adding Text-To-Speech
(TTS) and ADPCM speech processing applications to a range of portable devices. The highly integrated
design reduces overall system cost and time-to-market. The S1V30120 contains all the required analogue
codecs, memory, and EPSON-supplied embedded algorithms. All applications are controlled over a single
serial interface (SPI) allowing control from a wide range of hosts and rapid integration into existing products.
