NXP Semiconductors FS32K142HAT0VLLT

Overview

FS32K142HAT0VLLT from NXP Semiconductors is an automotive-grade Arm® Cortex-M4F microcontroller designed for real-time control in safety-critical ECUs. It operates at up to 112 MHz (HSRUN mode), features 256 KB flash with ECC, 256 KB SRAM with ECC, and supports -40 °C to 105 °C ambient operation in a 100-pin LQFP package. It integrates FlexCAN with optional CAN-FD, dual 12-bit ADCs (up to 32 channels), and CSEc cryptographic engine - deployed in body control modules requiring ASIL-B compliance.

For engineers reviewing the FS32K142HAT0VLLT datasheet, FS32K142HAT0VLLT pinout, FS32K142HAT0VLLT application, or FS32K142HAT0VLLT equivalent, key selection considerations include HSRUN/RUN mode switching constraints for EEPROM/CSEc operations, 100-pin LQFP footprint compatibility across S32K14x family, CAN-FD channel count (1x with FD), and voltage range (2.7–5.5 V) versus temperature grade (V = -40°C to 105°C).

Technical Context

The FS32K142HAT0VLLT implements a dual-core capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN) and integrated FPU, DSP, and NVIC. Its clock system includes SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz), enabling precise timing control across power modes.

Power management uses PMC with five defined modes (HSRUN, RUN, STOP, VLPR, VLPS); critical operations like CSEc execution or EEPROM write/erase are restricted to RUN mode (80 MHz), not HSRUN, due to hardware-enforced error flag generation. Memory subsystem includes ECC-protected flash and SRAM, FlexNVM for data storage, and QuadSPI with HyperBus™ support.

Key Specifications

Pinout & Package

FS32K142HAT0VLLT is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow the S32K14x family standard layout; all I/O pins support interrupt capability, and dedicated pins provide SOSC, RTC_CLKIN, SWD_CLK, TCLK, and FlexCAN transceiver interfaces.

FAQ

What is the maximum operating frequency of the FS32K142HAT0VLLT and under what conditions?

The FS32K142HAT0VLLT achieves up to 112 MHz in HSRUN mode, which requires VDD ≥ 2.7 V and ambient temperature ≤ 105 °C. However, CSEc cryptographic operations and EEPROM writes/erases are prohibited in HSRUN mode and must execute in RUN mode at 80 MHz. This dual-frequency constraint is enforced by hardware error flags to ensure reliability.

Does the FS32K142HAT0VLLT support CAN-FD, and how many channels are available?

Yes, the FS32K142HAT0VLLT includes one FlexCAN module with CAN-FD support, enabling data rates beyond 1 Mbps and payloads up to 64 bytes. The "F" in the ordering code "HAT0" confirms CAN-FD capability. This single CAN-FD channel is implemented on dedicated CAN0_TX/CAN0_RX pins and requires an external CAN transceiver for physical layer interfacing.

What package type and pin count does the FS32K142HAT0VLLT use?

The FS32K142HAT0VLLT uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with an exposed thermal pad. This package is pin-to-pin compatible with other S32K14x devices in the same footprint, including FS32K144HAT0VLLT and FS32K146HAT0VLLT, enabling scalable hardware design across memory/peripheral variants.

How does the FS32K142HAT0VLLT handle memory protection and functional safety compliance?

The FS32K142HAT0VLLT implements NXP's System MPU at the crossbar switch level - not Arm's core MPU - granting independent access rights to flash, SRAM, and peripheral regions for each master (CPU, DMA, Ethernet). Combined with ECC on flash/SRAM, CRC module, dual watchdogs (WDOG/EWM), and CSEc, it supports ASIL-B development per ISO 26262 without external safety monitors.

Can the FS32K142HAT0VLLT operate from a 3.3 V supply, and what are the voltage limits?

Yes, the FS32K142HAT0VLLT operates across 2.7 V to 5.5 V, fully supporting 3.3 V nominal supply. Absolute maximum VDD is 5.8 V for ≤60 seconds cumulative lifetime (non-reset condition); sustained operation must remain within 2.7–5.5 V. VDDA and VREFH must track VDD within ±0.1 V to maintain ADC linearity and I/O drive strength.
