Thailand-based NFC designer Silicon Craft Technology has developed a passive NFC transponder chip aimed at the toy, advertising and souvenir markets that harvests energy provided by an NFC interaction and uses it to power sounds and LED lights.
The SIC4310 NFC Enabler's UART interface can directly drive a piezo speaker to play melodies while its GPIOs (general purpose input/output pins) are able to turn LED lights on and off using only harvested power from an NFC device.
A short video from Silicon Craft shows how NFC Enabler can be used:
"We believe that there will be a huge demand for passively-operated and passive-powered NFC solutions," says managing director Manop Thamsirianunt. "Therefore, Silicon Craft is continuing to develop new revision with more features and capabilities including integrating sensors and a processor, targeted to be launched in 2014."
