你好朋友，我是新来的。

我在这里看到了很多很棒的 F1C 板。

我想自己画。我会尝试分享一些原理图供大家使用。

这里我画了一个F1CXXXS的电源设计：

许可证： 你选择的许可协议 署名-相同方式共享 4.0 国际 AMICA 板

我使用了 TMI 7003 B，因为我觉得它足以达到目的，而且更便宜。

我做了这些考虑/假设：

电压 F1CXXXS

M=最小值，T=典型值，X = 最大值，PS = 选择功率

真V
VDD-核心 - M 1.0 - T 1.1 - X 1.2 - PS 1.1 V
VCC-DRAM - M 2.3 - T 2.5 - X 2.7 - PS 2.5 V
AVCC - M 2.5 - T 2.8 - X 3.1 - PS 2.8 V
TV-AVCC - M 3.0 - T 3.3 - X 3.6 - PS 3.3 V
VCC-IO - M 3.0 - T 3.3 - X 3.6 - PS 3.3 V
UVCC - M 3.0 - T 3.3 - X 3.6 - RS 3.3 V

蒸馏 V
VDD-CORE - M1.0/T1.1/X1.2/PS 1.1V
VCC-DRAM AVCC - M2.5/T2.6/X2.7/PS 2.6V
TV-AVCC VCC-IO UVCC - M3.0/T3.3/X3.6/PS 3.3V

蒸馏电压是我用来计算 TMI 芯片电路的。我将使用 2.6V 来使 AVCC 和 VCC-DRAM 都满意。

如果您发现该电源设计中的任何错误，请告诉我。

还有谁能给我一个购买 Allwinner F1C200s 和 F1C100s 的链接吗？画完之后想买10-50件。

Hello friends, I am new here.

I see so many awesome F1C boards here.

I want to draw my own. I'll try to share some schematics for everyone to use.

Here I have drawn a power supply design for F1CXXXS:

License: Attribution-ShareAlike 4.0 International (CC BY-SA 4.0) . AMICA Boards

I used the TMI 7003 B as I feel that it will be sufficient for the purpose and also cheaper.

I made these considerations / assumptions:

Voltages F1CXXXS

M=Minimum, T=Typical, X = Maximum, PS = Chosen Power

True V
VDD-CORE - M 1.0 - T 1.1 - X 1.2 - PS 1.1 V
VCC-DRAM - M 2.3 - T 2.5 - X 2.7 - PS 2.5 V
AVCC     - M 2.5 - T 2.8 - X 3.1 - PS 2.8 V
TV-AVCC  - M 3.0 - T 3.3 - X 3.6 - PS 3.3 V
VCC-IO   - M 3.0 - T 3.3 - X 3.6 - PS 3.3 V
UVCC     - M 3.0 - T 3.3 - X 3.6 - RS 3.3 V

Distilled V
VDD-CORE            - M1.0/T1.1/X1.2/PS 1.1V
VCC-DRAM AVCC       - M2.5/T2.6/X2.7/PS 2.6V
TV-AVCC VCC-IO UVCC - M3.0/T3.3/X3.6/PS 3.3V

The Distilled Voltages is what I have used for calculationg the circuit for TMI Chip. I will be using 2.6V to make both AVCC and VCC-DRAM happy.

If you find the any bugs in that power supply design, please let me know.

Also can anyone send me a link to buy Allwinner F1C200s and F1C100s? I wish to buy 10-50 pieces after I finish drawing.
