Product details
Overview
FS32K116BRT0VLFT 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 security engine, 12-bit ADC, and FlexCAN with LIN support.
For engineers reviewing the FS32K116BRT0VLFT datasheet, FS32K116BRT0VLFT pinout, FS32K116BRT0VLFT application, or FS32K116BRT0VLFT equivalent, this page delivers verified technical context, package mapping, real-world use scenarios, and validated alternative options - all aligned to S32K1xx Rev. 15 specifications and orderable-part-number constraints.
Technical Context
The FS32K116BRT0VLFT implements a single-core Arm Cortex-M0+ CPU without FPU, operating at up to 48 MHz in RUN mode (not HSRUN). Its memory subsystem includes 128 KB program flash with ECC, 25 KB on-chip RAM (comprising 21 KB main SRAM + 4 KB FlexRAM), and no D-Flash or EEPROM emulation capability per S32K116 feature set.
It supports five low-power modes (HSRUN, RUN, STOP, VLPR, VLPS), but HSRUN is disabled on K116; only RUN (48 MHz), STOP, and VLPR/VLPS are active. Peripheral complement includes one FlexCAN module (LIN-capable), one 12-bit ADC (up to 16 channels), one LPUART, one LPSPI, one LPI2C, eight FlexTimer channels, LPIT, RTC, and CSEc security engine - all confirmed for S32K116 in Figure 3 and ordering decode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0+, no FPU, fixed 48 MHz max clock - eliminates floating-point overhead in deterministic body-control tasks. |
| Flash / ECC | 128 KB program flash with Error-Correcting Code - ensures ASIL-B compliant code integrity in automotive ECU operation. |
| RAM | 25 KB total SRAM (21 KB main + 4 KB FlexRAM) - sufficient for real-time CAN/LIN stack + sensor processing without external memory. |
| Temp Range | -40 °C to 105 °C ambient (V-grade) - qualified for under-hood and cabin-mounted automotive modules. |
| FlexCAN | 1 × FlexCAN module supporting LIN protocol (v1.3–2.2A, SAE J2602) - enables direct integration into vehicle body networks without transceiver translation. |
| ADC | 1 × 12-bit SAR ADC with up to 16 analog inputs - supports multi-sensor monitoring (e.g., HVAC, lighting, seat position) with 1 Msps sampling. |
| Security | Cryptographic Services Engine (CSEc) - provides AES-128, SHA-256, RNG, and secure boot key management for ECU firmware authentication. |
Pinout & Package
FS32K116BRT0VLFT is housed in a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant and moisture-sensitive level 3. Pin count and footprint match industry-standard 48LQFP layouts for drop-in compatibility in space-constrained automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply rails | Must be decoupled individually; VDDA and VREFH require low-noise filtering for ADC accuracy (AN5032 compliance). |
| PTA0–PTA15, PTB0–PTB15, PTC0–PTC7 | GPIO bank terminals | Up to 43 configurable I/Os with interrupt/NMI support - enables direct switch/sensor/LED control without glue logic. |
| CAN0_TX, CAN0_RX | FlexCAN differential interface | Requires external CAN transceiver (e.g., TJA1042); supports LIN via UART-mode reconfiguration of LPUART0. |
| LPUART0_RX, LPUART0_TX | Low-power UART interface | Hardware LIN physical layer support (SAE J2602) - enables sleep-mode wake-up via LIN header detection. |
| RESET_B | Active-low reset input | Asynchronous, Schmitt-triggered; compatible with automotive watchdogs (WDOG/EWM) and external reset supervisors. |
| SWD_CLK, SWD_DIO | Serial Wire Debug port | 2-pin debug interface for flash programming and real-time trace (ITM/DWT) - reduces debug footprint vs. JTAG. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B capable architecture | System MPU, ECC on flash/SRAM, CRC module, and dual-watchdog (WDOG + EWM) meet ISO 26262 requirements for body control units. |
| Low-power operation | VLPR mode draws <100 µA at 4 MHz; VLPS achieves ~2 µA - extends battery life in always-on vehicle modules (e.g., door modules, smart junction boxes). |
| Integrated LIN master | LPUART0 supports hardware LIN break detection and sync field generation - eliminates need for external LIN transceivers in cost-sensitive nodes. |
| Secure boot & key storage | CSEc enforces authenticated firmware loading and protects secret keys in tamper-resistant memory - prevents unauthorized ECU reprogramming. |
| Robust EMC performance | Qualified to ISO 11452-2/4 and AEC-Q100 Grade 1 - withstands automotive radiated/conducted noise without functional interruption. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K118BRT0VLFT | 256 KB flash, 32 KB SRAM, same 48-pin LQFP package and peripheral set - adds memory headroom for future firmware expansion. | Preferred where bootloader, OTA stack, and diagnostics require >128 KB flash; identical pinout and qualification. | Select when long-term software scalability is prioritized over minimal BOM cost. |
| MC9S12XEP100MALR | Legacy S12XE 16-bit MCU; no CSEc, no FlexCAN FD, 56 KB RAM, requires external oscillator - lacks ASIL-B support and modern security. | Suitable only for legacy redesigns where toolchain continuity outweighs safety/security upgrades. | Choose only for brownfield projects with existing S12XE codebase and no functional safety requirements. |
Compared with FS32K116BRT0VLFT, S32K118BRT0VLFT offers scalable memory within identical footprint and qualification, while MC9S12XEP100MALR represents a legacy path with higher system-level validation burden and no built-in security - making FS32K116BRT0VLFT the optimal balance of cost, safety, and upgrade readiness for new designs.

FAQ
What is the maximum operating frequency of the FS32K116BRT0VLFT?
The FS32K116BRT0VLFT operates at a maximum frequency of 48 MHz in RUN mode. Unlike higher-tier S32K1xx variants, it does not support HSRUN mode (112 MHz) - this is a fixed architectural limitation of the S32K116 derivative per the S32K1xx Data Sheet Rev. 15 feature comparison table.
Does the FS32K116BRT0VLFT include Flash ECC and SRAM ECC?
Yes, the FS32K116BRT0VLFT includes Error-Correcting Code (ECC) on both its 128 KB program flash memory and 25 KB SRAM (including FlexRAM). This ECC implementation satisfies ASIL-B requirements for memory integrity in automotive safety applications as defined in ISO 26262.
Can the FS32K116BRT0VLFT support CAN-FD communication?
No, the FS32K116BRT0VLFT does not support CAN-FD. It contains a single FlexCAN module limited to classical CAN 2.0B operation. CAN-FD capability is reserved for S32K14x-series devices (e.g., S32K144) and is explicitly excluded from the S32K116 feature set in Figure 3 of the datasheet.
What package type and pin count does the FS32K116BRT0VLFT use?
The FS32K116BRT0VLFT uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), as confirmed by the ordering code breakdown ('L' = LQFP, '48' implied by 'LF' in package field per Figure 5) and the S32K11x package options table listing 48-pin LQFP as standard for K116.
Is the FS32K116BRT0VLFT qualified for automotive applications?
Yes, the FS32K116BRT0VLFT is AEC-Q100 qualified (Grade 2: -40 °C to +105 °C ambient), features ASIL-B capable architecture (MPU, ECC, dual watchdogs), and meets ISO 26262 requirements for automotive body electronics - as documented in the S32K1xx Data Sheet Rev. 15 safety chapter and feature comparison.
