Holtek is delighted to announce the release of its new Touch Key peripheral ICs, the BS21xC-x series. One of the main features of these new devices is in their excellent cost/performance ratio. When compared with the previous BS81xC-x series, these new devices have resilient anti-power noise interference capabilities, have no external component requirements, have low power consumption and a high level of development convenience. These features combine to make the devices suitable for a huge variety of touch key product applications.
The BS21xC-x series includes the BS211C-1, BS212C-1, BS213C-1, BS214C-1, BS214C-2, BS216C-1, BS218C-2 and BS218C-3, all of which have excellent development convenience. This allows developers to apply them for use directly and rapidly in touch key product applications without having to invest effort in understanding touch key technology. The device’s internal circuits are able to implement automatic calibration according to environmental changes which further enhances their touch detection accuracy and stability. In addition, the BS211C-1, BS216C-1, BS218C-2 and BS218C-3 devices include a pin option for an IRQ function providing another level of application flexibility.
The BS21xC-x series provides 1~8 touch keys. With appropriate packaging and output interface design, these devices can meet various electronic product applications requirements. All are pin-compatible with the predecessor BS81xC-x series which will permit easy upgrades and thus shorten the product development cycle resulting in lower overall costs.
