• Manufacturer: Semtech

The Revision Status of the datasheet, as shown in the
center of the datasheet header bar, may be TARGET,
PRELIMINARY, or FINAL, and refers to the status of the
Device (not the datasheet) within the design cycle.
TARGET status is used when the design is being realized
but is not yet physically available, and the datasheet
content reflects the intention of the design. The datasheet
is raised to PRELIMINARY status when initial prototype
devices are physically available, and the datasheet
content more accurately represents the realization of the
design. The datasheet is only raised to FINAL status after
