        While the domestic market economy is normalizing , All industries have entered the new normal of steady growth , In order to pursue greater profits , Many enterprises have a growing demand for outdoor advertising , Strive to obtain greater revenue through outdoor advertising .

　　 Among them, outdoor LED Advertising screens have accounted for half of outdoor advertising , With its unique display effect, it has replaced countless advertising signs , Currently, the newly installed outdoor advertisements 85% Will choose LED Advertising screen , It can be seen that the market prospect is broad .LED There are many ways to install advertising screens , Wall mounted 、 Anti aircraft gun column installation 、 Hoisting 、 Inlay installation, etc .

　　 Some time ago, Xiaobian encountered an interesting thing that couldn't be laughed or laughed , There is a Guangxi Public Security Bureau LED The display screen is suddenly powered off , As a result, the data is missing , The result shows that （ Guangxi eight female corpses ）, This really scared more than Xiaobian , Through the timely repair of the supplier , Although the problem has been solved , But because of data loss , Made such a big Oolong joke ; Xiaobian also made a sweat for this unit ..... No more pictures , Avoid suspicion .

　　 see , I've just met such a funny thing , Xiaobian met an outdoor LED Advertising screen customers , He has been annoyed recently , Because the customer received some feedback and complaints , It gives him a headache .

　　 It used to be common outdoors LED Advertising screen , Because the power consumption is particularly large , Basically, there is no battery , They are all external power supplies . contrary , The mobile phones we often use have batteries , Even a sudden power failure has no effect on the device and data . And outdoors LED Billboards are not , In case of sudden power failure , Plus there is no battery buffer , If Flash If you are reading or writing at this time , The impact on it is very big , It can lead to Flash The data inside is missing and incomplete .

        There is no need to write bad block management in the driver NAND Flash（ Chip mounted TF card ）, Small size , Simple and easy to use , Strong compatibility , Stable and reliable , Firmware can be customized ,LGA-8 encapsulation , standard SDIO Interface , compatible SPI/SD/eMMC Interface , Compatible with all major MCU platform , It can replace ordinary TF card /SD card , Size 6x8mm mm , built-in SLC Wafer erasure life 10 Ten thousand times , adopt 1 10000 times of random power failure test, high and low temperature resistance , Support industrial grade temperature -40°~+85°, Machine stickers and hand stickers are very convenient , Speed level Class10（ Read speed 23.5MB/S Write speed 12.3MB/S） The standard SD2.0 The agreement is ordinary SD The card can be directly driven , Support TF Card activated SOC Both can be used. SD NAND, Provide STM32 Reference routines and original technical support , Mainstream capacity ：128MB/512MB/4GB, Than TF The card is stable , Than eMMC cheap , Sample free trial .

　　 Many advertisers come to him “ feedback ”, Just because of the outdoors LED The advertising screen suddenly loses power , The internal memory chip data is lost . It affects the advertising and brand effect of advertisers . Just keep complaining to him . Because of the sudden power failure , Why do advertisers react so much ？

　　1. Once the power is , The first is to arrange the repairman in time , Maintenance and repair of working at height , Labor and time , Need to waste a lot of costs .

　　2. Brand communication influence ： Once something goes wrong , No display and error display , It will affect the brand publicity effect of advertisers , If there is another Oolong incident ……. Therefore, this customer consulted leilong , Is there a power down protection NANDFlash. The above situation can be avoided .

　　 By coincidence , Our company just has one with power failure protection Flash product ——SDIONANDFlash, Thanks to the built-in controller and management firmware , Even in the event of a sudden power failure , It can also be perfectly guaranteed Flash Data integrity in . In case of sudden power failure , There is no need to pay the cost of labor and time to repair , It can also avoid the impact of the Oolong incident , Whether it's outdoors LED Manufacturers of advertising screens , Or advertisers have the role of improving the brand .

　　 And we have power failure protection NAND FLASH In addition to the built-in controller , There is also built-in bad block management ,EDC/ECC, Let the stability of the product go to a higher level .
