Voltage-level translator supports the Secure Digital 3.0 standard
The SD 3.0 specification provides up to 2 terabytes of storage capacity and accelerates SD interface read/write speeds to 50 megabytes per second, at 50 MHz Double Data Rate. The ST6G3244 couples high-speed operation with very low power dissipation, supported with the Power Down mode. Data integrity is secured through balanced propagation delays and electromagnetic-interference filters and signal conditioning. Recommended for portable devices that connect directly to the external memory card, ST’s newest voltage-level translator incorporates 15kV air-gap electrostatic discharge protection on the card side.
ST’s selectable-supply (1.8V or 2.9V), 6-bit bi-directional CMOS-level translator for SD, mini-SD and micro-SD memory cards is offered in a space-saving BGA25 package, reducing board area by more than 50% over current-generation devices (ST6G3238). It is backward pin-to-pin compatible with most existing SD 2.0 products, so customers can easily ‘hot swap’ and protect their investment in application development.
