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.

Allwinner claims “the advanced process design with lower voltage and lower leakage, the power optimization design for typical scenes, and the enhanced heat dissipation package, improve the heating experience (sic.) of the product” without details.

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.

Are you aware of the Allwinner H700 SoC ?

Still no info on frequency nor power consumption. I guess it’s close to the S3 which was found on to be 1.2 GHz (though no consumption info). The eLQFP package will probably take more room than an equivalent QFN. But overall these specs should allow to stuff it in plenty of devices.

I hope dgp sees this when they get up. That package and the 10 year lifespan could make this a great maker processor.

I’ve been keeping an eye on these for a while. I was more interested in the RISC-V versions but it looks like AW made a complete shit show that part so the ARM bit is probably the most viable. They seem to have fixed the major issue with the V3s that was if you boot from SPI flash you no longer have SPI for sensors etc. Looks like they have a memory mapped controller now too? Will be interesting to see that working. There is a bit of step backwards it seems though. They have gigabit ethernet now but you… Read more »

Do you have a Q1000+ price estimate for SSD202D? It is on taobao Q1 for $7.

But T113 much better for my use case. I would expect it to be priced similarly to SSD202D. I’m hoping T113 will be close to $4.

Current spot market for 2Gb DDR3 chips is $2.27. No quote for 1Gb.

Q1 on taobao they used to be ~$4.. I don’t have an official contact or distributor but the price I got from dodgy shenzhen parts broker was $3.8 each for a full tray of 2080. That was a little while ago though.

For Automotive Market this chip need to support at least 1 or 2 CAN/CANFD, Fault Control and managment features, also will need AEC-Q100 Certify, as far as I see still long way for this chip to be in Automotive Market
