Smart vehicles can not only enable an assistive driving system or a comfortable space inside a vehicle, but can also help control traffic, help prevent accidents by establishing a network of vehicle to vehicle(V2V) communication etc. V2V communication allows vehicles in transit to send the position and speed of another over ad hoc mesh network.

MicroSys Electronics has introduced the miriac MPX-S32G399A, a new System-on-Module (SoM) family for the control of smart vehicle networks. The new module offers an increase over the predecessor device with 33% higher real-time data processing performance for mixed-critical safety applications and 2.5 times more application processing performance. Major improvements include octal eight Cortex-A53 cores instead of four, as well as four Arm Cortex-M7 dual-core lockstep pairs instead of three.

The device benefits not only from more processor bandwidth for their safety-critical applications but also from the System-on-Modules’ inherent instant access to prototyping and extended connectivity for their dedicated use cases as well as comprehensive software support and safety documentation mandatory for certifications. The new System-on-Module offers multiple native CAN interfaces, as well as comprehensive FlexRay, LIN and TSN Ethernet support. Target markets are 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).

8 Arm Cortex-A53 cores and 4 Arm Cortex-M7 cores including lockstep support
Comprehensive connectivity including 18x CAN FD + dedicated protocol engine, furthermore FlexRay, LIN, SPI, Ethernet with TSN, PCI Express, USB and I²C
Hardware Security Engine for secure boot and accelerated security services
Low Latency Communication Engine (LLCE) for vehicle networks acceleration
Packet Forwarding Engine (PFE) for Ethernet networks acceleration.

In terms of memory, the new SoM integrates 4 GB of soldered LPDDR4 RAM at 3200 MT/s, up to 32 GB eMMC non-volatile memory, and 64 MB QuadSPI flash. External SD card storage can be multiplexed with the on-board eMMC.

In regard to 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, 3x 2.5 Gigabit Ethernet plus 3x Gigabit Ethernet, 18x CAN FD bus, 2x FlexRay, and 4x LIN. 14x GPIOs, 12x analog inputs (ADC), 4x FlexSPI, 2x UART, 1x USB and 4x 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.
