FS32K146HAT0VLHR

FS32K146HAT0VLHR is an NXP (Freescale) automotive-grade 32‑bit MCU from the S32K1 family, built around an ARM Cortex-M4F core. It targets automotive control and safety applications and provides robust peripherals, memory options, and security features suitable for automotive environments. The HAT0VLHR suffix encodes a specific package/temperature grade variant of the device.
Typical capabilities (as described in the datasheet): CAN/CAN-FD controllers, optional FlexCAN, LIN/UART, SPI/I2C, USB, Ethernet; multiple ADCs, DACs, PWM and timer modules; DMA/eDMA; CRC and cryptographic accelerators; memory protection unit and safety features for automotive use. It integrates Flash and RAM appropriate for embedded control software and is supported by NXP’s MCU ecosystem (SDKs, MCUXpresso).
For exact specifications (flash RAM sizes, package type, operating voltage, safety features, and availability), refer to the S32K146 datasheet and product selector on NXP’s website.

Closest equivalents are other members of the NXP S32K1 family. The nearest cross-refs are S32K146, S32K144 and S32K142 (same Cortex‑M4F core and similar peripherals). For a pin‑for‑pin substitute in the HAT0VL package, use NXP’s cross‑reference tool or distributors (Digi‑Key/Mouser). If looking beyond NXP, consider other Cortex‑M4F MCUs with comparable peripherals, noting pin/peripheral compatibility must be verified.
