The S32G Vehicle Network Processors family starts with four devices that are software and pin-compatible with the S32G2 Series launched earlier this year.

NXP says the new devices offer up to 2.5x more applications processing performance, which have up to eight ARM Cortex-A53 cores with ARM Neon DSP blocks. These are arranged in two clusters of four cores with optional cluster lockstep for applications and services. There are also up to four ARM Cortex-M7 dual-core lockstep (DCLS) complexes for real-time applications and up to 20 MB of on-chip System SRAM.
This compares to four A53 cores and three M7 cores in the previous S32G2 family hat arted production in March. This allows the G3 to double the number of isolation domains to 16, which are critical for future ECU consolidation. The substantial performance enhancements with the same package pinout meet the needs of more demanding software-defined vehicles, says the company.
The initial S32G399A device has been sampled to lead customers with a production launch targeted for Q1 2023.
The family includes the same Low Latency Communication Engine (LLCE) for automotive networks acceleration and there are three ports for the Packet Forwarding Engine (PFE) for Ethernet networks acceleration each supporting 2.5 Gbps and Advanced functional safety hardware and software for ASIL D systems
A Hardware Security Engine (HSE) provides secure boot and accelerated security services.
An EVB3 evaluation board, RDB3 reference design and GoldBox 3 rugged enclosure version, combined with software and the Vehicle Integration Platform (GoldVIP) for rapid connected gateway development provide platform solutions to accelerate customer evaluation, development, proof-of-concept and time-to-market.
Reference Software includes FreeRTOS support for the Cortex-M7 cores and Linux BSP support for the Cortex-A53 cores, as well as integration reference examples and board diagnostic tests.
Standard software includes real time drivers for AUTOSAR and non-AUTOSAR operating systems, Safety Peripheral Drivers, an Inter-Platform Communication Framework for communications between the Cortex-M7 and Cortex-A53 cores and hardware accelerator drivers and firmware.
Premium Software includes Premium Security with expanded security capabilities and Premium Safety, which includes the S32 Safety Software Framework for functional safety implementations and Structural Core Self Test (SCST) for the Cortex-A53 cores.
“With the industry move to more consolidated, software-defined vehicles, there is a need for more processing and memory,” says Brian Carlson, Global Marketing Director for Vehicle Control and Networking Solutions, NXP. “The new S32G3 Series builds on the success of the S32G2 Series processors, launched into production in April 2021, by providing a significant performance boost to extend its range of vehicle applications and meet new market demands.”
The S32G3 family is supported by the SJA1110 multi-gigabit safe and secure automotive Ethernet switch that is aligned to the latest TSN standards and offers integrated 100BASE-T1 PHYs, hardware-assisted security and safety capabilities and multi-gigabit interfaces. The PF53 12A core supply regulator with adaptive voltage positioning (AVP) supports the power management.
