Pinout & Package
FS32K142UFT0VLLT is housed in a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch), pin-compatible with other S32K14x devices in the same package variant. The device exposes 81 general-purpose I/O pins with interrupt capability, plus dedicated pins for SOSC, SIRC, FIRC, RTC_CLKIN, SWD, CAN, LIN, SPI, I2C, ADC, FlexTimer, and power domains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH, VREFL | Analog & digital supply rails | Separate but tightly coupled 2.7–5.5 V supplies; VDDA must be shorted to VDD on PCB per AN5032 for ADC accuracy |
| SWD_DIO, SWD_CLK | Serial Wire Debug interface | Two-pin debug port supporting JTAG/SWD protocols; enables non-intrusive trace, breakpoint, and flash programming |
| CAN0_TX, CAN0_RX | FlexCAN channel 0 differential pair | Supports ISO 11898-1 CAN 2.0B and optional CAN-FD; requires external transceiver for bus coupling |
| ADC0_SE0–ADC0_SE31 | Analog input channels (ADC0) | Up to 32 single-ended inputs across two 12-bit SAR ADC modules; 1 Msps sampling rate per module |
| FTM0_CH0–FTM0_CH7 | FlexTimer module 0 PWM/OC/IC outputs | Eight 16-bit timer channels configurable as edge-aligned PWM, input capture, or output compare for motor control |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Capable Architecture | System MPU enforces memory protection at crossbar level; ECC on flash/SRAM; CRC, WDOG, and EWM provide hardware-level fault detection |
| Low-Power Operation | Five power modes including VLPR (≤2 MHz) and VLPS (sub-μA stop mode); clock gating per peripheral reduces dynamic power in active states |
| FlexCAN with CAN-FD | Three FlexCAN modules; one supports CAN-FD (up to 5 Mbps data phase); message RAM with hardware acceptance filtering and loopback test mode |
| Secure Boot & Cryptography | CSEc implements AES-128/256, SHA-256, RSA-2048, and ECDSA; supports secure boot authentication and encrypted firmware update |
| Flexible Timing Resources | Eight FTM modules (64 total channels), LPIT (4-channel 32-bit timer), LPTMR, PDB, and RTC - enable synchronized PWM generation, wake-up timing, and time-stamped event capture |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K144UFT0VLLT | 512 KB flash, 512 KB SRAM, same 100-pin LQFP package and peripheral set | Required when application demands larger code footprint (e.g., AUTOSAR stack + diagnostics + OTA) or extended data logging buffers | Select FS32K144UFT0VLLT only if additional memory is needed; identical pinout and software compatibility reduce redesign risk. |
| FS32K142MT0VLLT | Same 256 KB flash/SRAM, but rated for -40 °C to +125 °C (M-grade) and uses 80 MHz RUN-only clock (no HSRUN mode) | Suitable for higher-temperature under-hood locations where 112 MHz operation is unnecessary; lacks HSRUN mode for peak performance | Choose FS32K142MT0VLLT for cost-sensitive thermal environments where 80 MHz determinism suffices and HSRUN is unused. |
Compared with FS32K142UFT0VLLT, FS32K144UFT0VLLT offers scalable memory without layout changes, while FS32K142MT0VLLT trades peak frequency for extended temperature range - enabling selection based on thermal budget and code size rather than feature compromise.

FAQ
What is the maximum operating frequency of the FS32K142UFT0VLLT and under what conditions?
The FS32K142UFT0VLLT achieves 112 MHz in HSRUN mode, enabled only when operating within the -40 °C to +105 °C ambient range and supplied with 2.7–5.5 V. In RUN mode, it runs at 80 MHz and supports wider temperature ranges including -40 °C to +125 °C for M-grade variants. The FS32K142UFT0VLLT datasheet specifies that CSEc operations and EEPROM emulation require switching to RUN mode to avoid error flags.
Does the FS32K142UFT0VLLT support CAN-FD, and how many CAN interfaces does it have?
The FS32K142UFT0VLLT integrates three FlexCAN modules, with one supporting CAN-FD (ISO 11898-1) at up to 5 Mbps data phase. This is confirmed in the S32K1xx datasheet Feature Comparison table and applies specifically to the K142 variant in 100-pin LQFP packages. All CAN modules support message RAM, hardware filtering, and loopback testing - essential for automotive network diagnostics and redundancy.
What safety certifications and hardware safety features does the FS32K142UFT0VLLT include?
The FS32K142UFT0VLLT is designed to support ASIL-B compliance per ISO 26262, featuring System MPU for crossbar-level memory protection, ECC on 256 KB flash and 256 KB SRAM, CRC module, internal watchdog (WDOG), external watchdog monitor (EWM), and lockstep-capable debug infrastructure. These features are documented in the S32K1xx datasheet Sections 1.1 and 3.1, and validated in NXP's functional safety documentation kit.
What is the purpose of the FlexRAM in the FS32K142UFT0VLLT, and how is it configured?
The FS32K142UFT0VLLT includes 4 KB of FlexRAM that can be dynamically allocated either as general-purpose SRAM or as EEPROM emulation storage. Configuration is controlled via FTFC registers and supported by NXP's EEPROM driver library. Unlike dedicated EEPROM, FlexRAM enables byte-level writes with no erase cycles - ideal for parameter storage in automotive ECUs where endurance and write latency matter. This behavior is explicitly defined in the S32K1xx Reference Manual Chapter "FTFC".
Is the FS32K142UFT0VLLT pin-compatible with other S32K1xx devices in the same package?
Yes - the FS32K142UFT0VLLT in 100-pin LQFP is pin-to-pin compatible with all other S32K14x and S32K14xW devices offered in the same 100-pin LQFP package, as stated in the S32K1xx datasheet Section 3.1 ("Feature comparison") footnote: "All devices which share a common package are pin-to-pin compatible." This allows hardware reuse across memory and feature variants without PCB redesign.
