The SX-Key Editor software version 1.30 is the first version to have integrated support for the SX18/28/48 and 52
chips. Previously, a different editor version was available for the 18/28 and 48/52 parts. This software supports
the production versions of the SX18/28 and SX48/52 chips. Production versions of the SX18/28 chips have a date
code that starts with the letter "A". Production versions of SX48 and SX52 chips have a date code of AA0004AA
or greater . Previous date codes of the SX chips will not be supported by future software or documentation . It is
recommended that Engineering Samples of SX chips be discarded.
