Exploring the Allwinner F1C200s Microcontroller

Following my successful project involving a Linux-running business card powered by the compact Allwinner F1C100s chip, I received positive feedback. Many enthusiasts shared that they found the chip for just 61 cents on Taobao, and some even requested samples or freelance work ideas based on it.

Allwinner kindly provided me with samples of their newer F1C200s chip, which is similar to the F1C100s but doubles onboard RAM to 64MB. They also sent datasheets and reference manuals for in-depth exploration.

The samples arrived well-packed on pick-and-place trays. To test the chip, I used a blank PCB to assemble a business card. With some free time, I quickly built a prototype using one of the samples. Based on datasheets and reference manuals, I expected minimal modifications to boot the system, since the peripherals and architecture are nearly identical to the F1C100s.

I flashed my image using the ‘sunxi-fel’ tool, which identified the device as an F1C100s due to the identical FEL mode output, making it impossible to distinguish between the two at this stage. The card successfully booted through U-Boot into Linux, which recognized the increased 64MB RAM automatically.

The Linux system startup confirmed the hardware’s recognition of the larger memory, with U-Boot showing the model as “George Hilliard’s business card.” This experiment demonstrated the F1C200s’s compatibility and potential for custom low-cost embedded projects.

In conclusion, the F1C200s offers a simple yet powerful platform for small-scale devices, combining affordability with familiar architecture. Its ease of use and ability to run Linux make it an attractive choice for hobbyists and developers seeking compact embedded solutions.
