Product details
Overview
FS32K146UAT0VLQT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (with ECC), and support for HSRUN mode at 112 MHz. It integrates FlexCAN with optional CAN-FD, dual 12-bit ADCs (up to 32 channels), CSEc cryptographic engine, and operates across -40 °C to 105 °C ambient temperature. Designed for body control modules and gateway ECUs requiring functional safety up to ASIL-B.
For engineers reviewing the FS32K146UAT0VLQT datasheet, FS32K146UAT0VLQT pinout, FS32K146UAT0VLQT application, or FS32K146UAT0VLQT equivalent, key selection considerations include its 100-pin LQFP package, 112 MHz HSRUN/80 MHz RUN dual-frequency operation, CSEc security execution constraints, FlexNVM EEPROM emulation capability, and CAN-FD readiness in automotive networked systems.
Technical Context
The FS32K146UAT0VLQT implements a dual-core architecture with Arm Cortex-M4F as primary CPU and M0+ for low-power background tasks, sharing AXBS-Lite crossbar and system MPU for memory protection. Its clock system combines SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz) with configurable gating per peripheral domain.
Power management includes five modes - HSRUN, RUN, STOP, VLPR, VLPS - with PMC-controlled transitions; CSEc operations and EEPROM writes require explicit switch from HSRUN (112 MHz) to RUN (80 MHz) mode to avoid error flag assertion. Memory subsystem features ECC on flash/SRAM, QuadSPI with HyperBus™ support, and FlexRAM configurable as SRAM or EEPROM emulation.

FAQ
What is the maximum operating frequency of the FS32K146UAT0VLQT and under what conditions?
The FS32K146UAT0VLQT operates at up to 112 MHz in HSRUN mode and 80 MHz in RUN mode. HSRUN mode requires VDD ≥ 2.7 V and ambient temperature ≤ 105 °C; RUN mode supports full temperature range up to 125 °C. The device must switch to RUN mode to execute CSEc cryptographic operations or FlexNVM writes/erases.
Does the FS32K146UAT0VLQT support CAN-FD, and what hardware is required?
Yes, the FS32K146UAT0VLQT includes three FlexCAN modules that support CAN-FD protocol via software configuration. External CAN-FD transceivers (e.g., TJA1044T) are required on the board; no additional MCU hardware is needed beyond proper pin assignment and clock setup for bit-rate switching.
How does the CSEc security engine function on the FS32K146UAT0VLQT?
The CSEc engine on the FS32K146UAT0VLQT implements SHE-compliant cryptographic functions including AES-128/256 encryption/decryption, SHA-256 hashing, HMAC, and true random number generation. It operates only in RUN mode (80 MHz); attempting CSEc commands in HSRUN mode triggers error flags and requires mode transition.
What package type and pin count does the FS32K146UAT0VLQT use?
The FS32K146UAT0VLQT uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. This package supports up to 81 GPIOs, all three FlexCAN interfaces, dual ADC modules, and full debug connectivity via SWD/JTAG pins.
Can the FS32K146UAT0VLQT emulate EEPROM, and how is it implemented?
Yes, the FS32K146UAT0VLQT supports EEPROM emulation using 64 KB of FlexNVM and 4 KB of FlexRAM. The S32 SDK provides drivers for wear-leveling, atomic write/erase, and ECC protection - eliminating need for external EEPROM while maintaining data retention over 100k cycles and 10-year endurance.
