Security module : TRNG, Crypto Engine(AES with DPA, TDES/SHA/RSA), Secure Boot.

Domestic Quanzhi A40I/T3 The brief introduction is as follows ：

AllWinner Of A40I/T3 Series chip is based on four cores ARM Cortex A7 Low power, high performance and low cost application processor of the kernel , The block diagram is as follows ：

Its main characteristics are as follows ：

Tetranuclear ARM Cortex-A7 kernel , The maximum running speed can reach 1.2 GHz;

Industrial control platform level chip , Support Android And Linux Dual system , Supply cycle of more than ten years
Industrial quality standards ,100ppm, working temperature -40-85℃

Support 32 Bit DDR3 data bus , More processing power ;

Support dual screen display and multiple display interfaces RGB/MIPI / double LVDS/HDMI, The biggest support 1920X1080 The resolution of the ;

Support multi-channel camera input ,DVP in*2/CVBS in*4

Support 3 individual MMC 4.5/SD 3.0/SDIO Interface ;

2 individual IEEE802.3 Standard Ethernet interface , One 10/100M, One 1000M.

3 individual USB 2.0 Interface , One of them OTG, 2 individual USB HOST Interface .

As many as 8 individual UART Interface .

CPU Internal integrated audio HEADPHONE headphone jack ,MIC Interface ;

And support SATA Interface ,8X8 Keyboard interface etc

summary ： After comparison, we found that ,A40I/T3 It's a quad core processor , and I.MX6UL It's a single core processor ,A40I/T3 More processing power ;A40I/T3/I.MX6UL There are also dual networks , however A40I/T3 One network is Gigabit , Stronger communication capability ;A40I/T3 Also has the SATA Interface and built-in audio , Higher cost performance ;

Yingpengfei embedded i.MX6ULL Core board

There are a lot of imx6ull The core board of the platform , Today I want to introduce a smaller size , No components on the back , Better value for money imx6ull Core board , This is an embedded product developed by yingpengfei . Let's take a look at the product pictures first :

  The core board is carefully laid out , Try to reduce the size , The existing size is 38*39mm, On such a small area , Integrated CPU,RAM,Flash, And it also integrates all the way PHY Ethernet chip , Small as the sparrow is , The five internal organs are complete .

To meet the needs of different application scenarios , The core board provides a variety of configurations , from D256MB+N256MB(nandflash) To  D512+E8G（emmc）, Applicable to most application scenarios .
