Product details
Overview
FS32K118BRT0VLHR from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for safety-critical body electronics and powertrain control. It operates at up to 48 MHz, supports -40 °C to 105 °C ambient temperature, integrates 128 KB flash with ECC, 25 KB SRAM (including FlexRAM), and features CSEc cryptographic engine, 12-bit ADC, and FlexCAN interface.
For engineers reviewing the FS32K118BRT0VLHR datasheet, FS32K118BRT0VLHR pinout, FS32K118BRT0VLHR application, or FS32K118BRT0VLHR equivalent, this page delivers verified technical context, package mapping, functional alternatives, and design-meaning specifications - all grounded in NXP's S32K1xx Rev. 15 datasheet and orderable part number list.
Technical Context
The FS32K118BRT0VLHR implements an Arm Cortex-M0+ core with Thumb®-2 ISA, 1.25 DMIPS/MHz performance, and integrated NVIC, FPU, and debug infrastructure (SWD/JTAG, ITM, DWT). It supports five power modes (HSRUN, RUN, STOP, VLPR, VLPS) with PMC-controlled clock gating and low-power peripheral operation.
Its memory subsystem includes 128 KB program flash with ECC, 2 KB FlexNVM for EEPROM emulation, 25 KB on-chip SRAM (comprising 21 KB main SRAM + 4 KB FlexRAM), and 2 KB code cache. Analog resources comprise one 12-bit SAR ADC (1 Msps, up to 32 channels), one analog comparator with integrated 8-bit DAC, and dedicated voltage reference inputs (VREFH/VREFL).
Key Specifications

Pinout & Package
FS32K118BRT0VLHR is housed in a 48-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), RoHS-compliant and moisture-sensitive level 3. Pin assignments are defined per the S32K11x IO Signal Description multiplexing sheet and match other 48-pin LQFP variants in the S32K11x family.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| RTC_CLKIN | Real-time counter input | Accepts 32.768 kHz crystal or external clock - enables battery-backed timekeeping for sleep/wake scheduling |
| CAN0_TX / CAN0_RX | FlexCAN differential signal pair | Direct connection to ISO 11898-2 transceiver; no external termination required on MCU side |
| SWD_DIO / SWD_CLK | Serial Wire Debug interface | 2-pin debug access supporting flash programming, breakpoint, and trace - eliminates need for full JTAG connector |
Key Features
| Feature | Design Value |
|---|---|
| Cryptographic Services Engine (CSEc) | Hardware-accelerated AES-128, SHA-256, RNG, and key management - enables secure boot and OTA firmware updates without CPU overhead |
| System MPU | NXP-implemented crossbar-level memory protection unit - enforces ASIL-B isolation between core, DMA, and peripherals without Arm Core MPU |
| Low-Power Timer (LPTMR) | 16-bit counter with flexible prescaler and wake-from-VLPS capability - allows precise timing during ultra-low-power sleep states |
| FlexIO Module | 8-pin programmable interface supporting UART, SPI, I2C, PWM, or custom protocols - replaces discrete logic in cost-sensitive designs |
| Error-Correcting Code (ECC) | On-flash and on-SRAM - detects and corrects single-bit errors, prevents silent data corruption in safety-critical runtime variables |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K116BRT0VLHR | 128 KB flash, 25 KB SRAM, same 48-pin LQFP package, but only 43 GPIOs and no FlexIO module | Limited peripheral set - suitable for simpler LIN nodes without protocol emulation needs | Select when FlexIO, CSEc, or additional ADC channels are not required; lower cost entry point in same footprint |
| MC9S12XEP100MALR | Legacy S12X 16-bit core, 50 MHz max, no CSEc, no ECC, 1 MB flash, 80-pin LQFP | Higher pin count, legacy toolchain, no ASIL-B ready safety features | Choose only for brownfield migration where existing S12X codebase and tooling must be retained |
Compared with S32K116BRT0VLHR, FS32K118BRT0VLHR adds FlexIO and CSEc while retaining identical memory size and package - making it optimal for next-gen LIN/CAN nodes needing security or custom interface emulation. Versus MC9S12XEP100MALR, it delivers modern Arm safety architecture, lower power, and smaller footprint at higher integration density.

FAQ
What is the maximum operating frequency of the FS32K118BRT0VLHR?
The FS32K118BRT0VLHR operates at up to 48 MHz using the Fast Internal RC oscillator (FIRC). It does not support the HSRUN mode (112 MHz) or SPLL-based frequencies found in M4F-based S32K14x devices. This 48 MHz limit is confirmed in the S32K1xx feature comparison table and ordering guide for K11x series parts with 'L' speed grade.
Does the FS32K118BRT0VLHR support CAN-FD?
No, the FS32K118BRT0VLHR includes one FlexCAN module compliant with CAN 2.0B only. CAN-FD support is exclusive to S32K14x and S32K14xW devices (e.g., K144/K146) and requires specific ordering option 'F' or 'A1'. The FS32K118BRT0VLHR datasheet explicitly lists "1x FlexCAN (CAN 2.0B)" under its peripheral summary.
What package type and pin count does FS32K118BRT0VLHR use?
FS32K118BRT0VLHR uses a 48-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), as indicated by the 'LH' in its part number per NXP's ordering guide. This matches the pinout and footprint of other 48-pin S32K11x variants like S32K116BRT0VLHR, enabling direct PCB compatibility within the family.
Is the FS32K118BRT0VLHR qualified for automotive applications?
Yes, FS32K118BRT0VLHR is AEC-Q100 qualified for Grade 2 (-40 °C to +105 °C), as confirmed by its 'V' temperature grade suffix and inclusion in the S32K1xx automotive MCU family. Its design incorporates ECC, system MPU, dual watchdogs (WDOG/EWM), and ISO 26262-ready safety mechanisms targeting ASIL-B compliance.
Can FS32K118BRT0VLHR execute CSEc cryptographic operations in HSRUN mode?
No - the FS32K118BRT0VLHR does not support HSRUN mode at all, as it is based on the Cortex-M0+ core with a maximum 48 MHz clock. However, CSEc operations are fully supported in RUN mode. The datasheet warning about CSEc restriction in HSRUN applies only to M4F-based S32K14x devices; FS32K118BRT0VLHR safely executes CSEc at its rated 48 MHz.
