Supported processors

KideRT supports the Arm Cortex-M cores listed below. Confirm the configuration for your device and board with our engineers.

Arm Cortex-M cores supported by KideRT

Supported Arm Cortex-M cores by architecture, from Armv6-M to Armv8.1-M, oldest first, with the processor features KideRT uses on each
Architecture	Cores	MPU	FPU	TrustZone	Stack limit check
Armv6-M	Cortex-M0+	MPUYes	No	No	No
Armv7-M	Cortex-M3	MPUYes	No	No	No
Armv7E-M	Cortex-M4 Cortex-M7	MPUYes	FPUYes	No	No
Armv8-M Baseline	Cortex-M23	MPUYes	No	TrustZoneYes	Stack limit check: Yes, Secure state only
Armv8-M Mainline	Cortex-M33 Cortex-M35P	MPUYes	FPUYes	TrustZoneYes	Stack limit checkYes
Armv8.1-M Mainline	Cortex-M52 Cortex-M55 Cortex-M85	MPUYes	FPUYes	TrustZoneYes	Stack limit checkYes

Memory protection needs a part with an MPU. With TrustZone, KideRT runs in either the Secure or the Non-secure state.

Device and board support

Start with the processor core. Support for your exact device and board depends on the available port and its hardware integration.

Share the following details so we can discuss KideRT support for your target.

Device and board: The processor part number, board name and any custom hardware.
Build and configuration: Your compiler, timer source and memory-protection requirements.

Contact us with the part number and application requirements to discuss whether KideRT can support your target and what porting would require.
