| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K146UJT0VMHR | 1 MB flash, 192 KB SRAM, no Ethernet or SAI; identical pinout and peripheral set otherwise. | Lacks IEEE 1588 Ethernet and audio interfaces-suitable for cost-sensitive gateways without time-sensitive networking. | Select when Ethernet and SAI are unused; reduces BOM cost while maintaining software compatibility and footprint. |
| S32K148UJT0VMHT | Same silicon, but in tray packaging (T vs R); identical electrical and thermal specs. | No functional difference-only logistics variation for small-batch prototyping vs volume production. | Choose VMHT for evaluation or low-volume builds; VMHR preferred for automated SMT assembly with tape-and-reel feeders. |
Compared with FS32K148UJT0VMHR, the S32K146UJT0VMHR reduces memory and removes Ethernet/SAI to lower cost for non-networked control nodes, while the S32K148UJT0VMHT offers identical functionality in tray packaging-making VMHR optimal for high-volume automotive manufacturing with pick-and-place integration.

FAQ
What is the maximum operating frequency of the FS32K148UJT0VMHR and under which conditions?
The FS32K148UJT0VMHR achieves 112 MHz in HSRUN mode, but only when ambient temperature remains ≤105 °C and supply voltage is ≥2.97 V (required for PLL operation). At higher temperatures (up to 125 °C), it must operate in RUN mode at 80 MHz-verified per Table 5 in the datasheet for M-grade devices.
Does the FS32K148UJT0VMHR support CAN-FD, and how many instances are available?
Yes, the FS32K148UJT0VMHR integrates three FlexCAN modules, all supporting CAN-FD per ISO 11898-1 with data rates up to 5 Mbps. Each module includes dedicated message RAM, acceptance filtering, and hardware timestamping-confirmed in the "Features comparison" section and Figure 3 of the S32K1xx Data Sheet Rev. 15.
Can the FS32K148UJT0VMHR execute CSEc cryptographic operations in HSRUN mode?
No. As explicitly stated in multiple sections of the datasheet (including Notes under "Power management", "Memory and memory interfaces", and "Safety and security"), CSEc execution or EEPROM write/erase triggers error flags in HSRUN mode. The FS32K148UJT0VMHR must switch to RUN mode (80 MHz) to perform these operations safely and reliably.
What package type and pin count does the FS32K148UJT0VMHR use?
The FS32K148UJT0VMHR uses a 144-pin LQFP package (package code LH), with 0.5 mm pitch and thermally enhanced exposed pad. This matches the "144-pin LQFP" option listed in the "Package" section and Figure 3 of the S32K1xx Data Sheet Rev. 15, and is pin-compatible with other S32K14x devices in the same package.
Is QuadSPI with HyperBus™ support available on the FS32K148UJT0VMHR in its 144-pin LQFP package?
Yes. Unlike the 100-pin LQFP variant (where QuadSPI is excluded), the FS32K148UJT0VMHR in 144-pin LQFP fully supports QuadSPI with HyperBus™ interface-as confirmed in the "Features comparison" table (Figure 3) and footnote "6" specifying that QuadSPI is not supported *only* for S32K148 in 100-pin LQFP.
