Hi all,
I am looking for a storage solution for a camera application with LPC4300. The storage should be high speed (>25 MBps) and have high capacity (minimum 2 GB). Ability to swap (SD card or pendrive) is a plus.
SD card might not be a solution since UHS-1 standard (DDR50 mode) is not supported. USB 2.0 pendrives are not fast enough. But the recent USB 3.0 pen drives are fast and also backward compatible with USB 2.0 and might be able to give a data rate of 25 MBps with a USB 2.0 HS port (sequential write). Anyone tested this? What is the maximum data rate achieved with USB Mass storage in host mode with LPC4300?
Thanks a lot!
