MCUXpresso SDK release package
The MCUXpresso SDK release package content is aligned with the silicon subfamily it supports. This includes the boards, devices, documentation, and middleware.
Device support
The device folder contains the whole software enablement available for the specific System-on-Chip (SoC) subfamily. This folder includes clock-specific implementation, device register header files, device register feature header files, and the system configuration source files. Included with the standard SoC support are folders containing peripheral drivers, toolchain support, and a standard debug console. The device-specific header files provide a direct access to the microcontroller peripheral registers. The device header file provides an overall SoC memory mapped register definition. The folder also includes the feature header file for each peripheral on the microcontroller. The toolchain folder contains the startup code and linker files for each supported toolchain. The startup code efficiently transfers the code execution to the main() function.
Board support
The board folder provides the board-specific demo applications, driver examples, and middleware examples.

Demo application and other examples
The demo applications demonstrate the usage of the peripheral drivers to achieve a system level solution. Each demo application contains a readme file that describes the operation of the demo and required setup steps. The driver examples demonstrate the capabilities of the peripheral drivers. Each example implements a common use case to help demonstrate the driver functionality.

IoT Sensing Software Development Kit (ISSDK)
The IoT Sensing Software Development Kit (ISSDK) is the embedded software framework enabling the NXP digital and analog sensors for IoT applications. ISSDK combines a set of robust sensor drivers and algorithms along with example applications that allow users to get started with using NXP IoT motion and pressure sensors.
ISSDK is being offered as a middleware component in MCUXpresso SDK.
