This clock design features a smooth transition of digits, automatic brightness adjustment, and brightness changes based on time-of-day settings. Adjustments can be made via Bluetooth or manual buttons. The flexible low-density FPGA is used as a display driver to handle protocol conversions and support applications with complex encoder schemes and multi-sensor interfacing or DSP. The GreenPAK supplies the ForgeFPGA with 1.1V and the power level-shifter with 1.8V and 3.3V. Additionally, our low-power Bluetooth® Low Energy (LE) 5.1 module enables communication with smart home or building systems. The light sensor ensures the clock operates correctly under various light conditions.

System Benefits:

  • Programmable logic​
  • Single power supply input
  • Low system cost​




  • Smart Home/Building
