Hello, we want to exchange an SD-card in an existing design by an eMMC because we expect a higher robustness compared to the SD-Card in a socket. The read/write bandwidth might also be higher (8 bit interface instead of 4 bit), but of cource this also depends on the type of flash, (MLC, SLC, ...) and the integrated controller. I read that the middleware supports eMMC. We have not used eMMC in the past and therefor have no real experience this this type of flash memory so I askey our distributor for advice which one we could use. Answer was that eMMC cannot be used with the Microcontroller because modern eMMC have a JEDEC interface, the CPU does not have it ?!? I was confused, be he is the specialist... Now my question: Can anyone give me a partnumber of an eMMC that is supported by the Keil Middleware and that I can connect to LPC 4357 or STM32F7xx ? Somewhere I read which version of eMMC standard is supported by the middleware (V4.2?) but I cannot find this right now. I found eMMC components V5.0 and V5.1, but I'm not sure about compatiblity with earlier specification versions. Thank you.
