w w w . D a t a S h e e t 4 U . c o m ZEN2044F PROGRAMMABLE UNIVERSAL COUNTER DESCRIPTION The ZEN2044F is a 24bit x 4ch. programmable universal counter LSI. The ZEN2044F can count phase-shifted pulse signals or up/down pulse signals generated from rotary encoders or linear scales. Since the counter response speed is as high as 33MHz(MAX), the ZEN2044F can be used in a variety of applications required high speed counting, including digital servo controls and precision measurements. As to command sets, the ZEN2044F has a compatibility with the ZEN2011P. The ZEN2044F can also monitor input signals and detect any abnormal input accompanied with noise or other disturbances, so that the reliability of counted values are secured.
