Allwinner 2023-2024 roadmap reveals A736/A737 Arm Cortex-A78/A76 processors

Allwinner Roadmap 2023 2024 automotive industrial SoCs

Allwinner should launch new Cortex-A76/A55 and Cortex-A78/A55 processors in 2024 according to the company’s roadmap including the Allwinner A736/A737 for tablets and the T736/T737 designed for automotive and industrial applications. In recent years, we’ve seen Rockchip and Amlogic introduce more powerful processors with the Rockchip RK3588 octa-core Cortex-A76/A55 processor and Amlogic A311D2 octa-core Cortex-A73/A53 or the more recent Amlogic S928X Cortex-A76/A55 for 8K TV boxes. But we’re still seeing some recent boards based on Allwinner Cortex-A7 32-bit processors, although recently we covered the Allwinner A523 octa-core Cortex-A55 processor for tablets. So today, I decided to go on a quest to find out whether Allwinner plans to use 64-bit Arm “big” cores in their future design. I first ended up on the linux-sunxi website where they list the Allwinner T736 octa-core “sun60i” processor with two Cortex-A76 cores and six Cortex-A55 cores, but no other details. This leads me to some “notes” […]

LoRaWAN IoT Button ships with open-source firmware, bootloader, and Android app

LoRaWAN is often used for asset tracking or environmental monitoring, for example, to track cattle location, or monitor temperature and humidity in a field, but n-Fuse’s “LoRaWAN IoT Action Button” enables human interaction and comes with open-source firmware, bootloader, and soon the source code for the Android app. Most of the n-Fuse STx-LR family of LoRaWAN nodes integrates environmental sensors but the LoRaWAN IoT Action Button is different with support supports single, double, and long presses, as well as tactile feedback. n-Fuse STx-LR family comes in three variants with the following key features: MCU – STMicro STM32L071KZU6 Arm Cortex-M0+ microcontroller @ 32 MHz with 192KB flash, 20KB RAM sta-lr – Action button with tactile feedback. stx-lr – TI HDC2080 environmental sensor (Temperature, Humidity), BMA400 motion sensor (acceleration), magnetic field sensitive Reed switch, ambient light sensor, and proximity sensor. ste-lr – Bosch BME680 environmental sensor with temperature, humidity, air pressure, and […]
