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.

♦ I²C Control Required for Two SD Cards

♦ On-Chip Power-On Reset/Brown-Out Reset
