The SAY IT! demonstration kit is an out-of-the-box solution and includes all required hardware and software components.

The system is built on the super low power, high performance 16-bit 78K0R core microcontroller from the 78K0R/KG3 family. The MCU offers up to 256K bytes of flash memory and 12KB of RAM, 20MHz operating frequency and a wide supply voltage range from 1.8-5.5V. The 78K0R/KG3 microcontroller includes a lot of useful peripherals on-chip to support different applications and save cost on external components. Some of the components constituting the chip are 16x16 hardware multiplier, buzzer output controller, BCD adjustment, and wide selection of serial interfaces, ADCs, DACs, 10 timers and more. The 78K0R/KG3 outputs voice signal using either one of the channels of the internal 8-bit DACs or one of the seven available on-chip 16-bit PWM timers.

The kit is supplied with the Audio Data Conversion Tool (CvADPCM) used to convert and download voice data on to the board using the USB port. The CvADPCM is a software tool, running as a Windows™ application on a PC and is used to convert WAVE files (PCM) into the required frequency with the file format of IAR Workbench loadable source code. The Adaptive Differential PCM (ADPCM) compression /decompression library for firmware is also provided in the kit. The library is extremely compact middleware, built in the IAR environment and is available free of charge for 8-, 16- and 32-bit microcontrollers from NEC Electronics.
