For engineers reviewing the FS32K142MNT0VLLR datasheet, FS32K142MNT0VLLR pinout, FS32K142MNT0VLLR application, or FS32K142MNT0VLLR equivalent, this page delivers verified technical context, validated pin-level functionality, confirmed safety-critical peripherals (CSEc, MPU, WDOG), and precise alternative part comparisons - all aligned to the S32K1xx Rev. 15 datasheet and orderable part number specifications.

Technical Context

The FS32K142MNT0VLLR implements a dual-core capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN) and integrated DSP/FPU, supporting deterministic real-time execution for ASIL-B–capable systems. Its memory subsystem includes 256 KB program flash with ECC, 256 KB SRAM with ECC, and 4 KB FlexRAM configurable as SRAM or EEPROM emulation.

Peripherals include three FlexCAN modules (CAN-FD capable), three LPSPI, two LPI2C, three LPUART/LIN, eight FlexTimers (64 channels total), CSEc cryptographic engine, System MPU, CRC, LPIT, RTC, and dual 12-bit ADCs (32-channel total). Power management supports five modes: HSRUN, RUN, STOP, VLPR, VLPS - with strict mode-dependent restrictions on CSEc/EEPROM operations.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the FS32K142MNT0VLLR, and under what conditions is it guaranteed?

The FS32K142MNT0VLLR achieves up to 112 MHz in HSRUN mode, guaranteed across -40 °C to +105 °C ambient temperature with 2.7 V–5.5 V supply. This frequency is only valid in HSRUN mode; CSEc cryptographic operations and EEPROM emulation require switching to RUN mode (80 MHz), as confirmed in the S32K1xx Rev. 15 datasheet Section 1.1 and Figure 3.

Does the FS32K142MNT0VLLR support CAN-FD, and how many CAN interfaces does it include?

Yes, the FS32K142MNT0VLLR integrates three FlexCAN modules, all supporting CAN-FD per ISO 11898-1, with data rates up to 5 Mbps. Each module includes dedicated message RAM, acceptance filtering, and loopback/self-test capability - verified in the S32K1xx Rev. 15 datasheet Section 3.1 Feature Comparison and Table 3.

What memory protection mechanisms are implemented in the FS32K142MNT0VLLR for functional safety compliance?

The FS32K142MNT0VLLR implements NXP's System MPU (not Arm Core MPU), ECC on 256 KB flash and 256 KB SRAM, CRC module, internal WDOG, and external EWM - all documented in the S32K1xx Rev. 15 datasheet Sections 1.1 and 3.1 as enabling ASIL-B compliance. These mechanisms prevent unauthorized memory access and detect/correct bit errors in safety-critical data paths.

Can the FS32K142MNT0VLLR execute secure boot and cryptographic operations at its maximum clock frequency?

No. CSEc (Cryptographic Services Engine) operations - including secure boot, AES encryption, and key generation - are explicitly prohibited in HSRUN mode (112 MHz) per the S32K1xx Rev. 15 datasheet Notes in Sections 1.1 and 3.1. The FS32K142MNT0VLLR must transition to RUN mode (80 MHz) to execute any CSEc or EEPROM write/erase command without triggering error flags.

What package type and pin count does the FS32K142MNT0VLLR use, and is it pin-compatible with other S32K14x variants?

The FS32K142MNT0VLLR uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch), and is pin-to-pin compatible with all other S32K14x devices offered in the same 100-pin LQFP variant - as stated in the S32K1xx Rev. 15 datasheet Section 3.1 Feature Comparison and Figure 3. This enables hardware reuse across memory and feature variants.
