Allwinner T113-S3 dual-core Cortex-A7 SoC features 128MB DDR3, targets automotive and industrial applications

Allwinner T113-S3 is a dual-core Cortex-A7 processor with 128MB DDR3 on-chip memory that is designed for smart control and HMI applications in the automotive and industrial sectors.

At first glance, the new processor looks quite similar to Allwinner S3, but with twice the number of cores. However there’s more to it, as a a HiFi4 DSP has been added for smart audio applications, the H.264 encoder is gone replaced by an MPJEG encoder, and the company claims support for “industrial level working temperature”, plus a 10-year life cycle. among other differences.

Some of the specific use cases for the processor include infotainment solutions such as “Car MP5 Player” or “Car Instrument solution” as well as industrial products such as HMI and PLC as shown above. The product brief does not list any operating system but Allwinner T113-S3 should support the usual Tina Linux (OpenWrt based) and Melis RTOS based on RT-Thread open-source real-time operating system.
