GENERAL DESCRIPTION

The Universal Sensors and Transducers Interface

(USTI-EXT) is a fully digital CMOS integrated circuit

based on novel patented methods for frequency,

period,

its

ratio,

duty-cycle

and

phase-shift

measurements.

This

IC

has

similar

metrological

performance as Excelera’s UFDC-1M-16 and same

functionalities as the USTI IC but can work in extended

operation temperature range from - 55 ºC to +150 ºC.

FUNCTIONAL BLOCK DIAGRAM

sensor applications. It offers high performance with

flexibility and requires minimum possible number of

external components.

The USTI-EXT can be easy included into digital

environment, controlled by an external microcontroller

(slave mode) or work independently as a separate

measuring unit without an external control (master

mode). The function selection can be configured in

both software and hardware.

The IC converts frequency-time parameters of signals

into digital, and provides interface to microcontroller,

DAQ or sensor system to read these digital results.

The USTI-EXT has 29 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 mode

and accuracy can be also selected by using any of

three possible interfaces (slave communication mode).

A communication interface type (RS232, SPI or I

2C)

can be automatically selected according to the circuit

connection.
