Product details
Overview
FS32K116BRT0VLFR from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for safety-critical body electronics and powertrain control. It operates from 2.7 V to 5.5 V, supports -40 °C to 105 °C ambient temperature (V-grade), delivers up to 48 MHz CPU frequency, and integrates 128 KB flash with ECC, 25 KB SRAM, and CSEc cryptographic engine - deployed in electronic control units requiring ASIL-B compliance.
For engineers reviewing the FS32K116BRT0VLFR datasheet, FS32K116BRT0VLFR pinout, FS32K116BRT0VLFR application, or FS32K116BRT0VLFR equivalent, this page provides verified technical context, validated package mapping, confirmed peripheral configuration, and real-world use-case guidance for automotive ECU design, functional safety integration, and low-power domain control.
Technical Context
The FS32K116BRT0VLFR implements a single-core Arm Cortex-M0+ processor with Thumb®-2 ISA support, no FPU, and fixed 48 MHz maximum operation (no HSRUN mode). Its memory subsystem includes 128 KB program flash with ECC, 25 KB on-chip SRAM (including FlexRAM), and 4 KB FlexRAM configurable as EEPROM emulation - all protected by NXP's system MPU at the crossbar switch level.
Peripherals are optimized for automotive domain control: one FlexCAN module (CAN-FD capable), two LPUART/LIN interfaces, two LPSPI modules, one LPI2C, one 12-bit ADC (up to 32 channels), one analog comparator with integrated 8-bit DAC, eight FlexTimer channels, one LPIT, one LPTMR, and CSEc security engine - all accessible via 43 GPIO pins in its 48-pin LQFP package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K142HRT0VLFR | Arm Cortex-M4F core, 80 MHz, 256 KB flash, 2x FlexCAN, 64-pin LQFP - adds FPU and higher performance. | Required for complex motor control algorithms or Ethernet-enabled gateways where M4F compute headroom is critical. | Select when migrating from K116 to higher-performance domains; requires PCB redesign due to larger package and different pinout. |
| MC9S12XEP100MALR | Legacy S12XE 16-bit core, 50 MHz, 1 MB flash, no CSEc, QFP-112 package - lacks modern safety/security features. | Suitable only for brownfield designs maintaining legacy toolchains; not qualified for new ASIL-B projects. | Use only for cost-sensitive legacy replacements; avoid for new designs due to discontinued roadmap and missing ISO 26262 support. |
Compared with FS32K116BRT0VLFR, FS32K142HRT0VLFR offers higher compute throughput and dual CAN-FD but increases layout complexity and BOM cost, while MC9S12XEP100MALR provides pin-compatible migration path for aging S12 designs but lacks ECC, CSEc, and functional safety certification - making FS32K116BRT0VLFR the optimal balance of safety, integration, and footprint for mid-tier automotive control.
