From evolution in size to revolution in instrumentation

UFDC-1 and UFDC-1M-16 are available now in 5 x 5 x 1.0 mm body, 32-pad, lead pitch 0.50 mm Micro Lead Frame package.

SWP, Inc. has announces that its both popular ICs of Universal Frequency-to-Digital Converters UFDC-1 and UFDC-1M-16 are available now in 5 x 5 x 1.0 mm body, 32-pad, lead pitch 0.50 mm Micro Lead Frame package (MLF).

This miniaturized package lets to use such ICs in different pensize measuring instruments and built it in various quasi-digital sensors and transducers in order to convert frequency-time parameters of electrical signals of sensing elements to digital, similar like ADC converts a voltage or current to digital for analog sensor’s output.

Both CMOS ICs are two-cannel universal frequency-to-digital converters that can work with any sensors from frequency-time signal domain group and convert frequency,
period, its ratio and difference, duty-cycle, duty-off factor, PWM signal, time interval, pulse width and space, rotation speed, pulse number, phase shift - to - digital. The UFDC-1 and UFDC-1M-16 have a high and constant selectable accuracy (programmable from 1 to 0.001 %) in a wide frequency range up to 7.5 MHz (120 MHz), scalable resolution from to 2.5×10-7 Hz to 45 Hz and non-redundant conversion time.

Both ICs can work in 16 measuring and one generating (8 MHz, quartz stabilized rectangular pulses) modes and have 3 popular serial interfaces.

Both ICs can work in 16 measuring and one generating (8 MHz, quartz stabilized rectangular pulses) modes and have 3 popular serial interfaces: RS232 (including a master communication mode), I2C and SPI. The main differences between the UFDC-1 and UFDC-1M-16 chips are low frequency range 0.05 Hz vs.1 Hz and conversion time (0.0002 ... 0.2) s vs. (0.00000625 ...0.00625) s respectively.

Typical applications include:

• Any frequency, period, duty-cycle, PWM, time interval, phase-shift, pulse number output sensors in order to produce a digital output.Digital sensors design.
• Smart (self-adaptive) sensors and systems due to programmable accuracy and non-redundant conversion time - adaptive possibilities of ICs automatically choice the conversion time depending on the given error of measurement and opposite.
• Multifunctional and multiparameters sensors for simultaneous detection various parameters proportional to frequency and duty-cycle carrying the information provided by sensing elements.
• Data acquisition (DAQ) boars and systems for frequency-time parameters of electric signals.
• Virtual instruments.
• Desktop universal frequency counters.
• Tachometers and tachometric systems.
• Handheld multimeters for frequency-time parameters of electric signals.
• High-end, mid- and low-range ABS.
• High accuracy programmable frequency-time parameters–to–digital converters for different measuring and communication applications.
• Advanced analog-to-digital conversion using voltage-to-frequency converters for remote sensors.

The UFDC-1 and UFDC-1M-16 have a high and constant selectable accuracy (programmable from 1 to 0.001 %) in a wide frequency range up to 7.5 MHz.
