MAX14500–MAX14503
The MAX14500–MAX14503 USB-to-SD™ card readers
provide 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 func-
tion to USB Hi-Speed (480Mbps) operation. The
MAX14500–MAX14503 have two modes of operation:
Pass Thru and Card Reader. In pass thru, the SD and
USB signals pass through the MAX14500–MAX14503
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 MAX14500–MAX14503 implement a Hi-Speed USB
card reader that operates independently of the host
microprocessor. All the capabilities of the full-speed
USB port and SD card slot are preserved with the addi-
tional feature that allows a faster way for a PC to read or
write to the SD card. The MAX14500–MAX14503 sup-
port SD high capacity SDHC cards. The 40-pin TQFN
version supports one SD card, while the 56-bump WLP
version supports two SD cards.
The MAX14500–MAX14503 feature advanced power-
saving modes to reduce power consumption in
portable applications. The low-power Sleep modes
allow the ability to disable internal circuit blocks, pro-
viding power-saving operating modes. The default
clock input for each part number is specified in the
ordering information. The MAX14500–MAX14503 fea-
ture the option to change the default values using the
I
2
C interface.
The MAX14500–MAX14503 are available in 5mm x
5mm, 40-pin TQFN, and 3.23mm x 3.5mm, 56-bump
WLP packages. These devices operate over a wide
supply voltage range and are specified over the -40°C
to +85°C extended temperature range.
