For engineers reviewing the FS32K118LAT0VLHT datasheet, FS32K118LAT0VLHT pinout, FS32K118LAT0VLHT application, or FS32K118LAT0VLHT equivalent, this page provides verified technical context, package mapping, functional alternatives, and design-critical timing/power/security constraints specific to the S32K118 variant in 48-pin LQFP.
Technical Context
The FS32K118LAT0VLHT 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 uses a single 48 MHz FIRC oscillator as primary clock source and supports HSRUN/RUN/STOP/VLPR/VLPS power modes via PMC.
Its memory subsystem includes 128 KB ECC-protected program flash, 2 KB FlexNVM for EEPROM emulation, 4 KB FlexRAM, and 25 KB total system RAM. Analog peripherals comprise one 12-bit ADC (1 Msps, up to 32 channels), one analog comparator with 8-bit DAC, and dedicated low-power timers (LPTMR, LPIT).

FAQ
What is the maximum operating frequency of the FS32K118LAT0VLHT?
The FS32K118LAT0VLHT operates at a maximum frequency of 48 MHz using its internal Fast Internal RC oscillator (FIRC). It does not include a PLL, so no higher-frequency modes like HSRUN (112 MHz) are available - unlike S32K14x devices. This fixed-clock architecture simplifies timing validation and reduces external component count in cost-sensitive automotive modules.
Does the FS32K118LAT0VLHT support CAN-FD?
No, the FS32K118LAT0VLHT supports only classical CAN 2.0B via its single FlexCAN module. CAN-FD capability is exclusive to S32K14x and S32K14xW devices per the official feature comparison table. For FS32K118LAT0VLHT, CAN message throughput is limited to 1 Mbps, and frame payload remains capped at 8 bytes.
What security features are implemented in the FS32K118LAT0VLHT?
The FS32K118LAT0VLHT integrates the Cryptographic Services Engine (CSEc), which provides AES-128 encryption/decryption, SHA-256 hashing, HMAC generation, and true random number generation. It supports secure boot with immutable root-of-trust and key provisioning via NXP's Secure Boot Kit - all validated against the SHE specification for automotive security compliance.
Is the FS32K118LAT0VLHT pin-compatible with other S32K1xx devices?
Yes - all S32K1xx devices sharing the 48-pin LQFP package (e.g., FS32K116LAT0VLHT, FS32K118LAT0VLHT) are pin-to-pin compatible per the datasheet. Peripheral signal mapping and power/ground pin locations match exactly, enabling hardware reuse across memory and feature variants without PCB modification.
What is the temperature grade and qualification standard for FS32K118LAT0VLHT?
The FS32K118LAT0VLHT is V-grade, qualified for -40 °C to +105 °C ambient operation and compliant with AEC-Q100 Grade 2. It meets ISO 26262 ASIL-B requirements through integrated safety mechanisms including ECC memory, system MPU, CRC unit, and dual watchdogs (WDOG + EWM), making it suitable for non-safety-critical but reliability-demanding automotive applications.
