Fairchild Semiconductor's Voltage Translator Simplifies Design in SD Card Applications

Fairchild Semiconductor (NYSE: FCS) brings designers of Secure Digital (SD) applications a solution that simplifies design with its low voltage, dual supply SD interface voltage translator. The FXL2SD106 has a built-in automatic direction control allowing the device to sense and control the direction the data should flow, without a direction control pin.

The FXL2SD106 with Built-in Automatic Direction Control Increases the GPIOs Available for Programming

This automatic direction control feature reduces design complexity by eliminating the need to program the General Purpose IO (GPIO) for direction control, and reduces the number of pins required for controlling the translator from 20 pins to 16 pins. This translator is ideal for applications using SD cards such as printers, laptop PCs, GPS systems and camera phones.

Fairchild’s FXL2SD106 is packaged in compact 2.5mm x 3.5mm, 16-pin DQFN packaging. DQFN packaging features no signal pins in the center of the package, allowing designers to easily bond this package to the board. With the pins at the periphery of the package, it allows for easier inspection and less rework, which accelerates design time.
