are intended for use in commercial applications. Applications requiring extended temperature range, unusual
environmental requirements, or high reliability applications, such as military, medical life-support or life-
sustaining equipment, are specifically not recommended without additional mutually agreed upon processing by
ZMD for such applications.
ZMD reserves the right to change the detail specifications as may be required to permit improvements in the
design of its products.

ASI-Safety Applications
The ASI4U is designed to allow replacement of A²SI ICs in existing board layouts and applications. However,
since the ASI4U provides additional data preprocessing functions at the data input channel, the fault reaction
time of an AS-i Safety module could increase by 40ms if some of the new features become activated by inten-
tion, by accident or hardware fault.
ZMD strongly recommends the use of the new ASI4U Safety-Mode, if the ASI4U shall replace the A²SI in exist-
ing ASI-Safety designs. Only then, the same fault reaction times as with the A²SI are guaranteed. For compati-
bility with the modified data input routing in Safety Mode, the user has to adapt the safety code table stored in
the external micro controller. Only such Safety Code Sequences that contain the value
1110
are permitted.
If the IC is operated in Safety Mode, the user must pay special attention that the
Synchronous Data I/O Mode
as
well as the
Data Input Filters
remain disabled by appropriate E²PROM configuration.
Application of the ASI4U in Standard Mode (no Safety Mode enabled) for AS-i Safety products is basically pos-
sible, if an additional Fault Reaction Time of 40ms is taken into account.
The user shall also obey the additional security advice regarding “Production and Repair of AS-i Safety Slaves”
that is available as an additional document form the ZMD web page
www.zmd.biz
.
0.3
Repair of ASI-Safety Modules
If an A²SI based ASI-Safety Module shall be repaired, it is
explicitly prohibited
to replace the A²SI IC with the
newer ASI4U IC. This is to exclude safety relevant deviations of module properties that can result from the dif-
ferent data input paths an the above mentioned possible increase in Fault Reaction Time.
The user shall also obey the additional security advice regarding “Production and Repair of AS-i Safety Slaves”
that is available as an additional document form the ZMD web page
