STMicroelectronics claims to have the first voltage-level translator compliant with the latest SD (Secure Digital) 3.0 standard.
The SD 3.0 standard is used for interfacing application processors or digital basebands to SD memory cards in mobile phones, tablets and digital cameras.
The SD 3.0 specification significantly increases storage capacity and access speed. It 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.
ST’s chip, the ST6G3244, is designed for low power operation and has a data integrity feature using balanced propagation delays and electromagnetic-interference filters and signal conditioning.
The 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 BGA25 package.
It is backward pin-to-pin compatible with most existing SD 2.0 products.
