Development board EVAL-UFDC
The EVAL-UFDC-1/UFDC-1M-16 evaluation board is a simple board for
experiencing the Universal Frequency-to-Digital Converter performance.
The UFDC-1 and UFDC-1M-16 do not require any external components to design
This 2-channel Evaluation Board allows selection of the 16
frequency-time parameters measuring modes and one generation mode (for calibration purpose).
Easy design of various digital sensors and sensor
systems including smart, self-adaptation and self-identification sensor.
All existing frequency, period, duty-cycle, time interval,
pulse-width modulated, pulse number and phase-shift output sensors and
transducers can be directly interfaced to the evaluation board.
TTL-compatible sensors outputs can be connected to the Evaluation Board
to measure any output frequency-time parameters and test the sensor
The EVAL-UFDC-1/UFDC-1M-16 evaluation
board is supplied with free software. The evaluation board interfaces to any personal computer running Windows XP or later,
via the serial RS232 or USB port. When using the USB interface
a USB to Serial (9-pin) DB9 RS232 adapter cable is
The results can be displayed with a a terminal programs for Windows,
LabView or by using the supplied software. The demo kit includes a CD with
Terminal V1.9B and the Evaluation Board Software V1.14. The software
allows calibration of the converters and saves the calibration value
into the converters memory.
Supply voltage 8..14V AC/DC
