Key Features#

New Features | Enhancements | Removed Features | Deprecated Features

New Features#

  • Upgraded FreeRTOS kernel to LTS version 11.1.0. The CMSIS OS2 layer and Segger SystemView components were also upgraded to support FreeRTOS 11.1.0.

  • Added the MPA Manager component to the SiSDK. The Memory Protection and Attribute Manager provides a service to configure a variety of memory regions with different qualifiers which are referred to as MPA manager attributes using the Memory Protection Unit (MPU). For example, it is possible to configure a memory region as read-only, non-executable, non-shareable or non-cacheable.

  • System Setup: Added a new sl_main component to manage the device initialization process. This component supports both baremetal and kernel-based applications, replacing the sl_system component. More information is available in the component documentation. For RTOS applications, a migration guide is available. Baremetal applications will be migrated automatically using Simplicity Studio or the SLC CLI: the sl_system_compatibility component will be added to the migrated projects.

    For RTOS applications, the initialization sequence is different and the main() function now operates within the context of an RTOS task.

  • Power Manager and Clock Manager: Introduced new APIs to support advanced use cases involving runtime clock configuration changes.

    • Added slx_power_manager_update_clock_info(), an advanced Power Manager API that refreshes internal oscillator usage data by reading the current CMU clock tree. This is intended for scenarios where the system clock (SYSCLK) is modified at runtime, which is not typically recommended but required by some applications.

    • Added sl_clock_manager_get_sysclk_source() and slx_clock_manager_set_sysclk_source() to retrieve and configure the SYSCLK source oscillator.

  • Clock manager:

    • Added the SL_CLOCK_MANAGER_CTUNE_MFG_HFXO_EN option, allowing users to enable or disable the use of CTUNE values from Manufacturing tokens in the User Data page for LFXO and HFXO calibration.

    • Added a new Clock Manager component, clock_manager_oscillator_calibration_override, which enables overriding default oscillator calibration values with those stored in NVM3. Currently, this feature supports the HFXO oscillator. The component provides new APIs to read, write, and delete HFXO oscillator override calibration values in NVM.

  • Peripheral HAL: Peripheral HAL is an alternative to EMLIB. Peripheral HAL supports Series 3 devices while EMLIB does not. HAL Peripheral also supports Series 2 devices. Note that for Series 2 devices, both EMLIB and Peripheral HAL components can co-exist in the same application (at the cost of increased code size). EMLIB components are not being deprecated and are still supported.

    • The following components and associated source files have been added: hal_acmp, hal_adc, hal_burtc, hal_dcdc_coulomb_counter, hal_emu, hal_eusart, hal_gpcrc, hal_iadc, hal_ldma, hal_leddrv, hal_letimer, hal_pcnt, hal_pixelrz, hal_prs, hal_sysrtc, hal_smu, hal_syscfg, hal_system, hal_timer, hal_usart and hal_wdog.

    • Refer to the documentation for more details.

  • Memory Manager: Added support for managing multiple heaps.

  • UARTDRV: Added a user callback parameter for the UARTDRV_Transmit() and UARTDRV_Receive() functions.

  • NVM3:

    • Enabled secure NVM3 write and read operations using the Host crypto engine instead of the SE crypto engine.

    • Users can use the nvm3_registerCallback() API to register a callback function, which is triggered when the NVM3 instance detects low memory conditions or a cache overflow. The callback allows the application to handle conditions such as freeing up memory by triggering repack. It is recommended that the callback be registered before calling any NVM3 APIs. Additionally, users can deregister the callback using the nvm3_deregisterCallback() API.

    • Users can query the cache size and memory information using the nvm3_getMemInfo() API. This API provides details about the current memory state, including available memory, cache status, and additional cache requirements.

  • Added support for GCC Link Time Optimization (LTO) (using the toolchain_gcc_lto component).

Enhancements#

  • Device Headers: Added instance macros LDMA_NUM, GPCRC_NUM and LDMAXBAR_NUM in Series 2 device headers.

  • Device Headers: Improved code quality in the startup and system files.

  • Device Headers: Added the device_supports_wisun provides feature for FG23 and ZG23 slcc components variants with 512kB flash and 64kB RAM.

  • The startup code now sets the MSPLIM register to help detect main stack overflows by triggering a UsageFault, including for non-TrustZone applications.

  • UARTDRV: Added an assertion to validate the baud rate before calculating ticks.

  • Updated the register operations for setting and clearing bits to use their corresponding alias for Series 2 devices and later to improve code size.

Removed Features#

Removed Feature Was Deprecated?
The sl_memory.h file has been removed. Yes
The sl_memory_region.h file has been removed. Yes
The sl_memory_config.h file has been removed. Yes
The emlib_core_debug_config.h file has been removed. Yes
The device_init_nvic component and its associated files have been removed. The interrupt_manager component is available as a replacement. Yes
The ram_interrupt_vector_init component and its associated files have been removed. The interrupt_manager component is available as a replacement. Yes
The silabs_core_sl_malloc component and its associated files have been removed. The memory_manager component is available as a replacement. Yes
The Power Manager has removed two features:
  • Transition events for entering and exiting EM3, along with the ability to subscribe to these events.
  • Requirements for EM2 as the lowest Energy Mode.
On Series 2 devices, the hardware fully manages the transition between EM2 and EM3. The device will enter EM3 if possible (i.e., no hardware requests are active on low-frequency oscillators that cannot operate in EM3); otherwise, it will enter EM2. Consequently, the Power Manager no longer differentiates between EM2 and EM3, treating both as EM2. The hardware autonomously optimizes power savings by shutting down components as needed, whether transitioning to EM3 or not. 		Yes
The AWS software components is removed as it's a thirdparty and deprecated by it's author. Yes

Deprecated Features#

Deprecated Feature Planned Removal Date
System Setup (sl_system) has been deprecated. The new System Setup component (sl_main) should be used when starting a new project. For existing projects:
  • Bare-metal applications can use the System Setup Compatibility Layer. This compatibility layer provides aliased functions, allowing existing applications to use the new System Setup (sl_main) with calls originally written for System Setup (sl_system). When upgrading an existing project to SiSDK 2025.6 using Simplicity Studio or the SLC CLI, the migration will occur automatically.
  • Applications with an RTOS will eventually need to migrate to System Setup (sl_main) manually. Please refer to the sl_system to sl_main migration guide to migrate your application. Note that sl_system remains in the SiSDK and is still supported. The deprecation warning can be suppressed by defining the SL_SUPPRESS_DEPRECATION_WARNINGS_SDK_2025_6 macro in your project. This will allow the project to compile without warnings and defer migration to sl_main.
 June 16, 2026
The sl_memory component was deprecated and replaced with memory_manager_region. June 16, 2026
Interrupt Manager: The SL_INTERRUPT_MANAGER_S2_INTERRUPTS_IN_RAM configuration has been deprecated in favor of the interrupt_manager_vector_table_in_ram component. Adding the component to a project will result in the same behavior as having SL_INTERRUPT_MANAGER_S2_INTERRUPTS_IN_RAM set to 1. Project upgrade to SiSDK 2025.6 thanks to Simplicity Studio or SLC CLI will automatically be updated. June 16, 2026
