Project EvaluationAllwinner A40i
TCW40 Cost-focused Linux HMI Module
A practical choice for mature embedded HMI products that need broad display and industrial I/O support without moving to a higher-cost application processor.
Known platform facts
Use verified information first.
ProcessorAllwinner A40i; quad-core Arm Cortex-A7
GraphicsMali-400 MP2; OpenGL ES 2.0 / OpenVG 1.1
MemoryDDR3, typically 1 GB; documented up to 2 GB
StorageeMMC, typically 8 GB; documented up to 64 GB
Operating systemsLinux and Android 7.1 support are documented
DisplayLVDS · parallel RGB/CPU · 4-lane MIPI DSI · HDMI 1.4
ConnectivityUSB 2.0 · dual Ethernet · UART/SPI/I²C · optional Wi-Fi/Bluetooth
Configuration note.
“Typically” describes the common documented configuration; “documented up to” describes documented capability. Neither is a guaranteed stock configuration.
Good starting fit
Discuss this path when the product needs:
- Cost-sensitive industrial panels and instrumentation
- Products with established Linux or Android 7.1 software
- Designs requiring RGB, LVDS, MIPI DSI or HDMI
- Projects that value broad legacy I/O and dual-Ethernet options
Project confirmation required.
Confirm display interface, software baseline, carrier-board I/O allocation, thermal design, lifecycle and production configuration before design-in.
