SNC81000S series is a four channel voice synthesizer IC with push­pull
direct drive circuit. It built in a powerful 8 bit controller and 24 I/O pins, and
it can support 16 direct single cap touch or 15 cap touch with multi touch it can support 16 direct single cap­touch, or 15 cap­touch with multi touch
function. Apart from the IC ROM itself, it can support external SPI flash, so
can store very rich content.
By programming through the controller user’s varied applications including By programming through the controller, user s varied applications including
voice section combination; key trigger arrangement, output control and
other logic functions can be easily implemented.

The SNC81000K series including SNC81020S, SNC81040S
to SNC81620S and the supported sound duration is from
20 seconds@6KHz to 620 seconds@6Khz. If the single chip @ @ g p
ROM is not enough to hold the all sound, it can support
external SPI flash, so you can put a lot of content inside or
even can update the cotent by replacing the SPI flash card.
The price range for the single chip is from USD0.17 to
