STMicroelectronics announces what it says to be the industry’s first voltage-level translator compliant with the latest Secure Digital 3.0 standard, which enables increased storage space and faster multimedia access on portable devices.

STMicroelectronics introduced today (30 January) what is reportedly the industry’s first voltage-level translator compatible with the latest SD (Secure Digital) 3.0 standard, which enables increased storage space and faster access to multimedia content, including music, videos and pictures.

The SD 3.0 specification provides up to two terabytes of storage capacity and accelerates SD interface read/write speeds to 50 megabytes per second, at 50 MHz Double Data Rate, according to a press release issued by the semiconductor maker. 

The increase in storage capacity and access speed of SD 3.0, together with the low static power consumption and compact package, is said to make the new level translator fit for interfacing application processors or digital basebands to SD memory cards in mobile phones, portable media players, tablets, digital cameras or personal navigation devices.

The ST6G3244 combines high-speed operation and low power dissipation with the power down mode. Data integrity is secured through balanced propagation delays and electromagnetic-interference filters and signal conditioning.

The translator reportedly reduces board area by more than 50 percent over current-generation devices (ST6G3238) and offers backward pin-to-pin compatibility with most existing SD 2.0 products.

The ST6G3244 price is US$0.84 per unit in quantities of 1,000 pieces.
