content: Hi, I created an account here because i'm loosing my mind... I'm searching for an IC that connects a micro SD card to USB, like a classic adaptater. I saw that GENESYS LOGIC does exactly that, but, they dont answer anyone for weeks. I tried the famous websites such as LCSC, Mouser, Digikey and all... Nothing.. If you have any idea, please help me...The major thing is that I need them quite soon.. It's for a quite big society and no one likes to wait.. I want to order just a bit for the tests right now, so don't wanna pay 50$ for 10pcs that will arrive in weeks out of Amazon for exemple.Link to the datasheet of a GL823 and Genesys website.Datasheet:https://www.electrodragon.com/w/images/c/cb/GL823K.pdfGenesys:http://www.genesyslogic.com/en/product_list.php?1st=1

content: I already sent 2 emails at Genesys, so did JLCPCB to getting back some of those.. No answers seems to come to either of us...I guess I have no choice to buy from aliexpres but I wanted a fast service just like JLCPCB...2 weeks ago I had hope that GENESYS would refill JLCPCB and that I could have my pcb in a few days instead of 1 month..

content: Sorry to hear. The chip mfr do not care about customer service unless you are a volume player. Many are just fine to support their local markets. Many times we had to communicate through an interpreter who phoned them up and spoke with them in Chinese so that we could purchase their parts or kits. That is common in this crazy industry. The chip shortages do not help either.LCSC however should be more responsive and have found that their sister company, JLCPCB to be quite responsive on support. Ordered many times with both JLCPCB and LCSC without issues.Do consider Aliexpress:GL823 is available from many good suppliers we have used including:VISEN Electronic chips storehttps://www.aliexpress.com/item/32694807461.html?spm=a2g0o.productlist.0.0.fd4420d7U3FDCf&algo_pvid=3f265cfb-792a-4722-8bc6-0ac421cd6e1d&algo_exp_id=3f265cfb-792a-4722-8bc6-0ac421cd6e1d-0If you need larger volumes, can share details of brokers of such parts in China. You can adjust the shipping fees to match your requirements. Sometimes you can work with the vendors in Asia to consolidate your goods so you can receive them in sync in a single batch lot. Freight forwarders are very good for this.So for example, VISEN and JLCPCB could both ship to your freight forwarder in Shenzhen who then will forward to you via DHL, etc. Have contact information for such forwarders if this is of interest.For future iterations of your design, consider Microchip USB2240-AEZG-06. It seems to be available at this time of writing. There should be tons of support from Microchip. Found them to be very supportive on past reviews of their USB hubs, power delivery designs, etc.In short, the offshore brands will be lower cost but landed costs may make the USA brands more attractive. Better stability with support from local semiconductor firms.

content: Thanks for all those informations, I already bought some GL823 and in ssop16 socket because the one you proposed to me are complicated to solder.. But ok I'll remember about microchips maybe for later uses and VISEN. Thanks again !
