It operates at up to 112 MHz in HSRUN mode, supports CAN-FD, Ethernet (10/100 Mbps), and IEEE-1588 timing, and targets body control modules, gateway ECUs, and advanced driver assistance systems requiring ASIL-B compliance.

For engineers reviewing the FS32K148UGT0VLQR datasheet, FS32K148UGT0VLQR pinout, FS32K148UGT0VLQR application, or FS32K148UGT0VLQR equivalent, this page delivers verified technical context, package-specific pin mapping, safety-critical feature implementation details, and validated alternative options for automotive ECU design and qualification.

Technical Context

The FS32K148UGT0VLQR implements a dual-core capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN) and optional M0+ co-processor support via software configuration. It integrates SPLL-based clock generation, configurable power modes (HSRUN, RUN, STOP, VLPR, VLPS), and system-level safety mechanisms including ECC on flash/SRAM, System MPU, CRC, WDOG, and EWM.

Its mixed-signal subsystem includes two 12-bit ADCs (1 Msps, up to 32 channels each), one analog comparator with 8-bit DAC, and precision timing resources: eight FlexTimers (64 PWM/IC/OC channels), LPIT (4-channel), LPTMR, PDB, and RTC. Communication is enabled by three FlexCAN modules (all with CAN-FD), three LPUART/LIN, three LPSPI, two LPI2C, FlexIO, QuadSPI with HyperBus™, and one Ethernet MAC with IEEE-1588 timestamping.

FAQ

What is the maximum operating frequency of the FS32K148UGT0VLQR in HSRUN mode?

The FS32K148UGT0VLQR achieves a maximum CPU frequency of 112 MHz in HSRUN mode, delivering 1.25 Dhrystone MIPS per MHz. This high-speed operation is supported across the full −40 °C to +105 °C ambient range, though CSEc security operations and EEPROM writes must be executed in RUN mode (80 MHz) to avoid error flag generation.

Does the FS32K148UGT0VLQR support CAN-FD, and how many controllers are integrated?

Yes, the FS32K148UGT0VLQR integrates three independent FlexCAN modules, all supporting CAN-FD (ISO 11898-1) with data rates up to 5 Mbps. Each controller includes message RAM, acceptance filtering, and loopback/self-test modes - enabling redundant or multi-domain CAN-FD networks in gateway and domain controller applications.

What package type and pin count does the FS32K148UGT0VLQR use?

The FS32K148UGT0VLQR uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. It provides 73 GPIOs with interrupt capability, matching the pinout of other S32K14x devices in the same package variant - ensuring hardware reuse across family members.

How does the CSEc security engine function in the FS32K148UGT0VLQR?

The Cryptographic Services Engine (CSEc) in the FS32K148UGT0VLQR implements SHE-compliant AES-128/256, SHA-256, RNG, and key management. It operates only in RUN mode (80 MHz); attempting CSEc operations in HSRUN mode (112 MHz) triggers error flags. Secure boot, encrypted firmware updates, and runtime key isolation are enforced through hardware-protected regions.

Is Ethernet connectivity supported on the FS32K148UGT0VLQR, and what standards does it meet?

Yes, the FS32K148UGT0VLQR includes a 10/100 Mbps IEEE-802.3 Ethernet MAC with full IEEE-1588-2008 Precision Time Protocol (PTP) support. It implements hardware timestamping, VLAN tagging, and RMII interface - enabling time-synchronized communication for vehicle gateways, ADAS synchronization, and TSN-ready architectures.
