Application-ready automotive gateway platform for commercial vehicles, mobile machinery and many other functional safety uses
The miriac MPX-S32G274A System-on-Module (SoM) by MicroSys Electronics comes with 1 GHz quad Arm Cortex-A53 cores with Arm Neon technology that is organised in two clusters for applications and services. For real-time tasks, there are triple Arm Cortex-M7 dual-cores and combines ASIL D safety and hardware security standard comparable to IEC 61508. The SoM offers multiple native CAN interfaces as well as comprehensive FlexRay, LIN and Ethernet support. Target markets include real-time connected vehicles, mobile machinery and automotive test and measurement equipment. Further applications include data loggers, edge gateways and fail-safe programmable logic controllers (PLCs).
In terms of memory, the new SoM integrates 4GB of soldered LPDDR4 RAM at 3200 MT/s, 16GByte eMMC non-volatile memory, and 64MB QuadSPI flash. External SD card storage can be multiplexed with the onboard eMMC.
With native support for a total of 18 CAN interfaces, the new SoM is ideal for developing comprehensive vehicle networks. Alternative designs that use generic expansion buses to connect CAN controllers generate high interrupt loads on the main processor. FPGAs are not an inexpensive alternative either; they also require additional development resources for FPGA programming.
“The MicroSys miriac MPX-S32G274A is the world’s first System-on-Module to integrate the new NXP S32G2 processor, which was developed specifically for vehicle networks. OEMs benefit from an application-ready building block for their connected real-time controllers in automotive and other functional safety applications. They also benefit from high computing performance, faster Ethernet and automotive connectivity including massive native CAN support, plus comprehensive functional safety and security features,” explains Ina Sophia Schindler, CEO of MicroSys Electronics.
“System-on-Modules such as the MicroSys miriac MPX-S32G274A SoM help engineers to accelerate their designs by allowing them to concentrate on the application development. It is way easier and more efficient to implement an application-ready super component including processor, RAM and flash than to re-invent the wheel and start with a full-blown custom design from scratch,” explains Carlos Prada, Global Partner Director at NXP Semiconductors.
In all these application areas, the new MicroSys SoM provides value with its AEC-Q100 Grade 2 (-40°C to 105°C) qualified processor. The Low Latency Communication Engine (LLCE) for automotive networks is optimised for data transfers, as well as, its Packet Forwarding Engine (PFE) for Ethernet networks, greatly reducing the CPU workload. A Hardware Security Engine (HSE) for secure boot and encrypted data transfer provides the required comprehensive root of trust for connected IoT edge devices.
Regarding connectivity, the new SoM offers an extensive range of generic and communication interfaces including 4x SerDes interfaces configurable as PCIe Gen3 2×1 or 2×2, 4x Gigabit Ethernet, 18x CAN FD bus, 2x FlexRay, and 4x LIN. 14x GPIOs, 12x analogue inputs (ADC), 3x SPI, 2x UART, 1x USB and 3x I2C complete the interface range. For trace and debug tasks, the SoM supports Aurora and JTAG interfaces. A comprehensive board support package including bootloader configuration and all required Linux drivers rounds off the feature set.
Besides application-ready hardware and function-validated hardware-related software, MicroSys Electronics also offers customer-specific carrier boards and system-level design services. These extend to SIL certification for any markets where functional safety standards analogue 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) are also greatly simplified by the existing manufacturer documentation.
The new MPX-S32G274A SoM from MicroSys Electronics is available as an application-ready off-the-shelf component as well as a development kit with carrier board, cable set and cooling solution.
