for software driver.
Application Development Kit (ADK) - S32K EVB, power
adaptor board and 16-LED bar.
OVERVIEW
ISELED is a new communication protocol for controlling static
and dynamic LED arrays in automotive and industrial lighting
applications. It addresses calibration and communication
issues in today’s LED systems by moving the costly external
processes for ensuring stable light parameters (brightness
and color stability), to embedded processing in the RGB
LED. NXP’s 32-bit Arm Cortex-M based, automotive-qualified
S32K1 MCUs support the ISELED protocol with an ISELED
software driver available for use with its production-grade
SDK or in the AUTOSAR environment.
FEATURES
Smart LED Module
Contains RGB LEDs + INLC100Q16 ISELED Driver IC
(Inova Semiconductor) in single package. LED pre-
calibrated during manufacture with data stored in driver
IC – no speed-binning or look-up table in main S32K
control MCU.
Color control using standard RGB value sent from S32K
control MCU. Temperature sensor for auto-compensation.
ISELED Communication Protocol
Address up to 4079 LEDs at video speed.

The ADK contains a standard S32K MCU
sample which can only be used with the
free-of-charge evaluation version of the
ISELED software driver which re-initializes
after 10,000 ISELED commands. For
production, developers should order
one of the S32K ISELED part numbers
in the table below which include the full
production license with unlimited driver
functionality.
S32K MCU ISELED SOFTWARE
NXP provides the ISELED software driver
that runs within the production-grade
SDK included in the free-of-charge
S32 Design Studio IDE. An application
example is available via the FreeMASTER
plug-in tool which provides real-time
data visualisation and debugging.
