Product details
Overview
S32K310NHT0VPAST from NXP Semiconductors is an ASIL-B certified automotive-grade Arm® Cortex-M7 microcontroller operating at up to 120 MHz, featuring 512 KB program flash with ECC, 112 KB SRAM with ECC (including 96 KB TCM), and support for -40 °C to 125 °C ambient operation across all power modes. It integrates dual 24-channel 12-bit ADCs, three FlexCAN modules with CAN FD, four LPUARTs, and a hardware security engine (HSE-B) for AES acceleration - deployed in body control modules, gateway ECUs, and battery management systems.
For engineers reviewing the S32K310NHT0VPAST datasheet, S32K310NHT0VPAST pinout, S32K310NHT0VPAST application, or S32K310NHT0VPAST equivalent, key selection criteria include its single-core Cortex-M7 architecture, ASIL-B functional safety compliance, 512 KB ECC-protected flash, 96 KB tightly coupled memory for deterministic real-time control, and native CAN FD support across three channels - critical for automotive domain controller and chassis subsystem designs.
Technical Context
The S32K310NHT0VPAST implements a single Arm Cortex-M7 core with FPU and DSP extensions, executing at up to 120 MHz under Armv7/Thumb-2 ISA, and includes I-cache and D-cache to reduce memory latency. Its memory subsystem comprises 512 KB on-chip program flash with ECC, 64 KB data flash with ECC, and 112 KB SRAM with ECC - of which 96 KB is TCM RAM optimized for zero-wait-state CPU access.
Timing and control are managed via two 24-channel eMIOS timer modules, one 32-bit RTC with autonomous periodic interrupt, and full cross-triggering between ADCs and timers through BCTU. Power management uses PMC with RUN/STANDBY modes and peripheral-specific clock gating, enabling low-power wake-up on up to 60 GPIO pins.

FAQ
What is the maximum operating frequency of the S32K310NHT0VPAST?
The S32K310NHT0VPAST features an Arm Cortex-M7 core rated for up to 120 MHz operation. This frequency is achievable across the full -40 °C to 125 °C ambient temperature range and 2.97 V to 5.5 V supply voltage, with internal PLL configuration and proper decoupling. The S32K310NHT0VPAST does not support frequencies above 120 MHz - higher-speed variants (e.g., S32K322/S32K342) operate at 160 MHz but are distinct part numbers with different flash/SRAM allocations and safety ratings.
Does the S32K310NHT0VPAST support CAN FD, and how many channels are available?
Yes, the S32K310NHT0VPAST integrates three FlexCAN modules, all fully supporting CAN FD protocol with bit rates up to 5 Mbps and payload lengths up to 64 bytes. Each channel includes dedicated TX/RX pins, message RAM, and flexible filtering - enabling concurrent communication on multiple vehicle subnets (e.g., powertrain, chassis, infotainment) without software arbitration overhead. The S32K310NHT0VPAST does not support CAN XL or legacy CAN-only modes exclusively.
What memory protection mechanisms are implemented in the S32K310NHT0VPAST?
The S32K310NHT0VPAST implements Error-Correcting Code (ECC) on all on-chip memories: 512 KB program flash, 64 KB data flash, and 112 KB SRAM (including 96 KB TCM). It also includes Memory Protection Unit (MPU) support, XRDC-based cross-domain access control, and CRC modules for data path integrity. These mechanisms are active at boot and runtime - essential for ASIL-B compliance. The S32K310NHT0VPAST does not include parity-only protection or unprotected memory regions.
Is the S32K310NHT0VPAST pin-compatible with other S32K3xx family members?
Within the same package variant (MAPBGA437), the S32K310NHT0VPAST shares identical pinout and electrical characteristics with S32K311NHT0VPAST and S32K312NHT0VPAST - enabling direct PCB reuse. However, it is not pin-compatible with LQFP48, HDQFP100, or MAPBGA257 variants of the S32K3xx family. The S32K310NHT0VPAST pin mapping is fixed per its MAPBGA437 mechanical outline and cannot be reconfigured to match smaller packages.
What debug interfaces does the S32K310NHT0VPAST support?
The S32K310NHT0VPAST supports Serial Wire Debug (SWD) via a 2-pin SWJ-DP interface, plus full CoreSight trace capabilities including SWO, ITM, DWT, HTM, and ETB. It enables real-time instruction tracing, hardware watchpoints, and flash patching without halting execution. The S32K310NHT0VPAST does not support JTAG-only debugging - SWD is the primary and recommended interface, with JTAG functionality disabled by default in production configurations.
