The Universal Frequency-to-Digital Converter (UFDC-1M-16) is a fully digital CMOS integrated circuit based on novel patented methods for frequency, period, its ratio, duty-cycle and phase shift measurements.

The main difference between the UFDC-1M-16 and the UFDC-1 is that the first one has 32 times faster conversion speed. By using this IC it is possible to build a wide variety of digital, smart sensors and intelligent sensor systems. The device provides a high-resolution signal measurement and conversion to digital for wide range sensor applications.

As with the UFDC-1, the UFDC-1M-16 can be controlled by an external microcontroller (slave mode) or work independently as a separate measuring unit without an external control (master mode).

The UFDC-1M-16 has 16 measuring and one generating modes. The measuring mode can be hardware-selected by using four selection external pins M0-M2 and the relative error by using four selection pins N0-N2 (RS232 master communication mode).


The communication interface type (RS232, SPI or I2C) can be selected according to the circuit connection.
