MAX14502 EVALUATION KIT AVAILABLE Hi-Speed USB-to-SD Card Readers with Bypass General Description The MAX14502 USB-to-SD™ card reader provides a means for portable devices that support full-speed USB communication (12Mbps) with one or two SD card slots, upgrading the USB SD card reader function to USB high-speed (480Mbps) operation. The MAX14502 has two modes of operation: Pass Thru and Card Reader. In pass thru, the SD and USB signals pass through the MAX14502 without modification, appearing like the device is not present. The host microprocessor firmware does not need modification, as there is no change from the host microprocessor’s perspective. In Card Reader mode, the MAX14502 implements a high-speed USB card reader that operates independently of the host microprocessor.
