It operates at up to 112 MHz in HSRUN mode (−40 °C to +105 °C), supports CAN-FD, FlexCAN, Ethernet, and QuadSPI with HyperBus™, and targets body control modules and gateway ECUs.
For engineers reviewing the FS32K148UIT0VLQR datasheet, FS32K148UIT0VLQR pinout, FS32K148UIT0VLQR application, or FS32K148UIT0VLQR equivalent, key selection considerations include its 100-pin LQFP package, dual 12-bit ADCs (32-channel total), 3x FlexCAN modules with optional CAN-FD, IEEE-1588 Ethernet MAC, and mandatory RUN-mode execution for CSEc/EEPROM operations.
Technical Context
The FS32K148UIT0VLQR implements a dual-core architecture with Arm Cortex-M4F as primary core and M0+ for safety monitoring, supporting ASIL-B compliance via System MPU, ECC on flash/SRAM, CRC, WDOG, and EWM. Its clock system integrates SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz), with configurable power modes including HSRUN, RUN, STOP, VLPR, and VLPS.
Memory subsystem includes 2 MB program flash with ECC, 64 KB FlexNVM for data flash/EEPROM emulation, 256 KB SRAM with ECC, 4 KB FlexRAM, and 4 KB code cache. Peripheral set features three LPUART/LIN, three LPSPI, two LPI2C, three FlexCAN, one 10/100 Mbps Ethernet MAC with IEEE-1588, two SAI, and eight FlexTimers (64 PWM/IC/OC channels).

FAQ
What is the maximum operating frequency of the FS32K148UIT0VLQR and under what conditions?
The FS32K148UIT0VLQR achieves up to 112 MHz in HSRUN mode, validated across −40 °C to +105 °C ambient temperature. However, cryptographic operations (CSEc) and EEPROM writes/erases require switching to RUN mode at 80 MHz, as these functions are prohibited in HSRUN mode per datasheet specification. The device automatically triggers error flags if attempted at 112 MHz.
Does the FS32K148UIT0VLQR support IEEE-1588 Precision Time Protocol, and how is it implemented?
Yes, the FS32K148UIT0VLQR integrates a hardware IEEE-1588-capable Ethernet MAC with timestamping registers and PTP event message handling. It supports one-step and two-step clock synchronization, with hardware-assisted timestamp insertion on transmit and capture on receive - enabling sub-microsecond time alignment critical for zonal ECU architectures and time-triggered networks.
What package type and pin count does the FS32K148UIT0VLQR use, and is it pin-compatible with other S32K14x devices?
The FS32K148UIT0VLQR uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Per the S32K1xx datasheet, all S32K14x devices sharing the 100-pin LQFP package are pin-to-pin compatible - enabling scalable design reuse across memory and feature variants without PCB redesign.
Can the FS32K148UIT0VLQR execute CSEc security functions while running at 112 MHz?
No. The FS32K148UIT0VLQR explicitly prohibits CSEc (Cryptographic Services Engine) operations - including AES encryption, SHA hashing, and secure boot verification - when operating in HSRUN mode at 112 MHz. The device must transition to RUN mode at 80 MHz to execute any CSEc command, otherwise it asserts error flags and halts the operation.
How many CAN-FD interfaces does the FS32K148UIT0VLQR support, and what is their configuration flexibility?
The FS32K148UIT0VLQR integrates three independent FlexCAN modules, each supporting CAN-FD per ISO 11898-1 with bit-rate switching (up to 5 Mbps data phase). All three modules are fully configurable via software - enabling mixed classic CAN and CAN-FD operation, programmable message buffers, and hardware acceptance filtering - making it ideal for multi-domain vehicle networks.
