FAQ

What is the maximum operating frequency of the S32K328GHT1VPCST?

The S32K328GHT1VPCST features two independent Arm Cortex-M7 cores each operating at up to 240 MHz. This frequency is supported across the full −40 °C to +125 °C ambient temperature range and 2.97 V to 5.5 V supply voltage, enabling deterministic real-time execution in demanding automotive environments. The S32K328GHT1VPCST achieves this performance with zero-wait I/D-TCM and dual PLL clocking.

Does the S32K328GHT1VPCST support CAN FD, and how many channels are available?

Yes, the S32K328GHT1VPCST integrates eight FlexCAN modules, each supporting full CAN FD functionality with data rates up to 5 Mbps. All eight channels are independently configurable for different bit rates and message buffers, making the S32K328GHT1VPCST suitable for high-bandwidth automotive networks such as those used in domain controllers and EV powertrain systems.

What package type and pin count does the S32K328GHT1VPCST use?

The S32K328GHT1VPCST is offered in a MAPBGA437 package: a 17 mm × 17 mm ball grid array with 437 I/O balls and an exposed thermal pad. This package supports high-density automotive PCB layouts and provides robust thermal performance for sustained operation in under-hood applications. The S32K328GHT1VPCST pinout is documented in NXP's S32K3xx Reference Manual Rev. 14.
