Innovation is one of the HolyLite’s core values. Since HolyLite has been established in 1989, we have dedicated in developing analog and digital IC for different kinds of applications. Currently, we have six product lines which are the following:
Holylite always insists with none-reverse design, we have the whole process from idea generation to products application all by ourselves. Since we have made the first one Speech recognition IC in Taiwan, we continued going forward and developing the first one infrared heart pulse detector IC, hand-held heart pulse detector IC in the world and the first one touch sensor IC, 13.36MHz RFID IC in Taiwan.
As times change, human interface and integrated marketing had developed and had been the trend in the recent years. For this reason, we research comprehensive and easy-operated solutions to meet your needs and find out chances for business collaboration. Thinking about new designs that would inspire innovation and change our lives would always be a challenge for us. You could find more product information on our website. We value any suggestions or comments.
Detect the heartbeat signal through 3 sensors, and then process the tiny heartbeat analog signal through the differential amplifier circuit.
The tiny heartbeat analog signal passes through an analog circuit composed of an amplifier to eliminate noise from the sensor chip.
The HL8042A Heart Pulse Detector is a single chip AC type photo-sensing heart pulse detection system. With built inpower regulator, HL8042A has higher immunity to power noise induced by buzzer or other devices. HL8042A receives and amplifies the heart pulse signal from external photo sensor with a fewexternal components.

This demo is base on HL5311 RFID electrical Dice with HL5612 touch pad application. You can ask Dahrma to tell your fortune by rolling the wheel pads. We put HL5311 RFID electrical dice into "Dahrma" figure. This fortune e-Dice has 6 grades . When you decide to ask a question, you can start to roll the pads. After several turns, the "Dahrma" get enough power and starts to roll the fortune e-Dice. Finally, you will find how luckiness by lightening LED.
