Holtek is delighted to announce the release of its standard Touch Key peripheral ICs, the BS81xC-x series. Compared with the previous BS81xA-x series, these new devices have more resilient anti-power noise interference abilities (CS), higher touch key response sensitivity, better power saving logic characteristics and higher development convenience. These features combine to make the devices suitable for various AC or battery powered touch key product applications.
The BS81xC-x series includes the BS811C-1, BS812C-1, BS813C-1, BS814C-1, BS814C-2, BS816C-1,BS818C-2, BS818C-3, BS8112C-3 and BS8116C-3, which all have excellent development convenience, allowing developers to apply them for use directly and quickly in products without requiring software development. Using IC external touch keys to sense the touch action of human hands, the internal circuits are able to implement automatic calibration according to environmental changes, which can further enhance the accuracy of touch detection. The devices include an IRQ function to provide an additional level of application flexibility.
The BS81xC-x series provides 1~16 touch keys. With appropriate packaging and output interface design, these devices can meet various electronic product application requirements. all pin-compatible with the BS81xA-x series, which can thus shorten the product development time resulting in lower costs.
