MicroSys Electronics announced a module built around NXP’s S32G3 vehicle network processor at Embedded World 2022.
Intended for real-time mixed-critical safety applications, “thanks to the NXP S32G3 processor, the MPX-S32G399A system-on-module surpasses its NXP S32G2-based predecessor with 2.5 times more application processing performance,” according to MicroSys.
Improvements include eight Arm Cortex-A53 cores instead of four, as well as four Cortex-M7 dual-core lock-step pairs instead of three.
The A53 core have Arm’s Neon technology organised in two clusters for applications and services. For the lock-step M7 pairs, MicroSys offers support for dedicated FreeRTOS implementations beside NXP’s standard automotive support. “Clustered and operated in lock-step mode, the set of heterogenous cores of the S32G3 can support ASIL-D applications or any other functional safety standard comparable to IEC 61508,” it said.
4Gbyte of soldered LPDDR4 RAM is included, operating at 3.2Gtransfer/s. Up to 32Gbyte of eMMC non-volatile memory and 64Mbyte QuadSPI flash can also be present, and external SD card storage can be multiplexed with the on-board eMMC.
The module offers multiple native CAN interfaces, as well as FlexRay, LIN and Ethernet support including TSN (time-sensitive networking).
In detail, there are 4x serdes configurable as PCIe Gen3 2×1 or 2×2, 3x 2.5Gbit Ethernet plus 3x Gbit Ethernet, 18x CAN FD bus, 2x FlexRay and 4x LIN.
These are accomanied by 14x GPIOs, 12x ADC inputs, 4x FlexSPI, 2x UART, 1x USB and 4x I2C. For trace and debug tasks, Aurora and JTAG interfaces are supported.
The board support package includes bootloader configuration and Linux drivers, and there is “safety documentations mandatory for certifications”, said MicroSys.
The company is aiming its module at “any market where functional safety standards analog to IEC 61508 are required, including railway technology – EN 50155, aviation – DO-160, stationary and mobile machinery – ISO 13849, as well as manufacturing robots -ISO 10218, control systems – IEC 62061 – and drive systems – IEC 61800‑5‑2. Approvals in the aviation context – DO-254/DO-160 – can be supported with manufacturer documentation”.
Further applications are foreseen in data loggers, edge gateways and fail-safe programmable logic controllers.
Series production is scheduled for Q1 2023, with OEM evaluation kits appearing this year, with carrier board, cable set and cooling.
