The ZIOL2xxx IC Family Overview
IDT provides a universal and IO-Link compatible cable driver IC by issuing the ZIOL2401 integrated circuit. The
ZIOL2401 is highly configurable and suitable for a wide range of applications in process and factory automation.
In order to fulfill the requirements of specific applications stripped down versions of the IC were required. The
ZIOL2xxx IC family is derived from the ZIOL2401 by modification (elimination or disabling) of certain functional
building blocks. In this combination the following building blocks or functions are affected:
•
•
•
The transceiver channels COM and AUX
The availability of the integrated DC/DC converter
The activation of a read-only data access via the SPI interface
This datasheet describes the entire IC family ZIOL2xxx. Respective notes or footnotes describe the availability the
above mentioned building blocks or functionality with respect to certain IC family members. Table 1.1 shows an
overview concerning the ZIOL2xxx IC family and the used naming convention.
