Hi-Speed USB-to-SD Card  
Readers with Bypass  
–MAX14503  
General Description  
Features  
USB 2.0 Hi-Speed and Full-Speed Compliant  
SDHC Card Support  
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.  
Internal Hi-Speed USB SD Card Reader Eases  
Host µP Overhead  
On-Chip Termination and Pullup Resistors  
Internal SD Switches Allow For Multiplexing Two  
SD Cards on a Single-Microprocessor SD Port  
Accommodates Clock Input Frequencies  
26MHz, 19.2MHz, 13MHz, and 12MHz  
Internal Clock Squarer for Low-Amplitude TCXO  
Signals  
No Power-Supply Sequencing Required  
Compatible with +1.8V to +3.3V I/O Host  
Microprocessor  
Simple Control Mode Requires Only a Single  
GPIO  
I2C Control Provides Multiple Configuration  
Options  
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  
I2C interface.

PACKAGE  
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.
