The S32K3xxDS is a powerful microcontroller with an Arm Cortex-M7 core that operates at speeds up to 300 MHz, delivering 2.14DMIPS per MHz. It has a voltage range of 2.97V to 5.5V and can operate in temperatures ranging from -40°C to 125°C in all power modes. The Arm Cortex-M7 core is based on the Armv7 and Thumb-2 ISA, providing high performance and efficiency. Additionally, the microcontroller features an integrated Digital Signal Processor (DSP), a Configurable Nested Vectored Interrupt Controller (NVIC), and a Single Precision Floating Point Unit (FPU) for enhanced processing capabilities. In terms of clock interfaces, the S32K3xxDS supports an 8-40 MHz Fast External Oscillator (FXOSC) and a 48 MHz Fast Internal RC oscillator for precise timing and synchronization. These clock interfaces ensure reliable operation and synchronization of different components within the microcontroller. Overall, the S32K3xxDS is a versatile and high-performance microcontroller that is well-suited for a wide range of applications, from industrial automation to automotive electronics. Its advanced features and capabilities make it an ideal choice for developers looking to design complex and efficient embedded systems.

1. This feature set is under evaluation and subject to change.

2. Final DMIPS is in range based on compiler setting. Low number is using "ground rules" laid out in the Dhrystone documentation. High number is using inlining of

functions.

3. ASIL-B and ASIL-D performance is available simultaneously.

4. Core configuration is 2xLS + 1 independent core

5. Core configuration is 1xLS + 3 independent cores

6. Result depends on specific compiler version, contact NXP sales representative for more details.

7. 4-bit data width, SDR mode only

5.1 Absolute maximum ratings

When the MCU is in an unpowered state, current injected through the chip pins may bias internal chip structures

(for example, ESD diodes) and incorrectly power up these internal structures through inadvertent paths. The

presence of such residual voltage may influence different chip-internal blocks in an unpredictable manner and

may ultimately result in unpredictable chip behavior (for example, POR flag not set). Once in the illegal state,

powering up the chip further and then applying reset will clear the illegal state. Injection current specified for the

chip under the aspect of absolute maximum ratings represent the capability of the internal circuitry to withstand

such condition without causing physical damage. Functional operation of the chip under conditions - specified

as absolute maximum ratings - is not implied.

CAUTION

Functional operating conditions appear in the DC electrical characteristics. Absolute maximum ratings are stress

ratings only, and functional operation at the maximum values is not guaranteed. See footnotes in the following table

for specific conditions. Stress beyond the listed maximum values may affect device reliability or cause permanent

damage to the device. All the limits defined in the datasheet specification must be honored together and any

violation to any one or more will not guarantee desired operation. Unless otherwise specified, all maximum and

minimum values in the datasheet are across process, voltage, and temperature.

NOTE

The VDD_HV_B and V15 voltage supply domains are only present in certain devices and packages (S32K388, S32K358,

S32K348, S32K338, S32K328, S32K344, S32K324, S32K314, S32K342, S32K341, S32K322).

The VDD_DCDC supply voltage is only present in certain devices and packages (S32K358, S32K348, S32K338, S32K328).

1. All voltages are referred to VSS unless otherwise specified.

2. 6.0 V maximum for 10 hours over lifetime; 7.0 V maximum for 60 seconds over lifetime.

3. Voltage at VDD_DCDC cannot be higher than VDD_HV_A.

4. Absolute max rating must be honored under all conditions, including current injection.

5. When input pad voltage levels are close to VDD_HV_A (respectively to VDD_HV_B) or VSS, practically no current injection

is possible. See application note AN4731 for a description of injection current on NXP automotive microcontrollers.

6. TSTG specifies the storage temperature range. It is not the operating temperature range. Please refer to the Thermal

operating characteristics table.

5.2 Voltage and current operating requirements

Device functionality is guaranteed down to the LVR assert level, however electrical performance of 12-bit ADC,

CMP with 8-bit DAC, IO electrical characteristics, and communication modules electrical characteristics will be

degraded when voltage drops below 2.97 V.

NOTE

The VDD_HV_B and V15 voltage supply domains are only present in certain devices and packages (S32K388, S32K358,

S32K348, S32K338, S32K328, S32K344, S32K324, S32K314, S32K342, S32K341, S32K322).

The VDD_DCDC supply voltage is only present in certain devices and packages (S32K358, S32K348, S32K338, S32K328).
