2. Function Overview
The S1V3034x evaluation kit comes with S1V3034x evaluation boards, power supply battery, microSD card,
and other accessories. The S1V3034x evaluation board consists of the NIJYO slave board incorporating an
S1V30340 voice LSI (hereafter "voice LSI") and a CASTLE master board with a host CPU for voice LSI
control. These two boards are used in a stacked configuration.
The S1V3034x evaluation boards are designed for standalone operations without a PC. Fig. 2-1 shows the
procedural flow when using the evaluation boards. The host CPU on the CASTLE board reads out the voice
data in the microSD card on the CASTLE board, then transmits the voice data to the S1V30340 on the
NIJYO board via serial I/F based on message protocol specifications. The voice data is decoded by the
S1V3034x and output as audio signals via the audio amplifier. Voice data can be created on the microSD
card using the EPSON Speech IC Speech Guide Creation Tool provided with this evaluation kit.
