Smart-card interface saves on power draw

Maxim Integrated Products has rolled out a low-power smart-card interface aimed at financial terminals, STBs and other smart-card reader applications. The DS8113 performs level translation between a host MCU and a 5V, 3V, or 1.8V smart card, while supplying up to 80mA for smart-card operation.

The DS8113 promises the industry's lowest-power stop mode, which allows applications to support smart-card communication and draw only 10nA while the card is inactive. In addition, it provides 8kV ESD protection to protects applications from damage during card insertion and removal. The device meets all ISO 7816, EMV, and GSM 11.11 specifications.

Replacement interface
The DS8113 is a replacement upgrade for devices with higher power consumption and no stop mode such as the TDA8024 and the ST8024. This smart-card interface allows designers to improve the performance of their applications with few or no changes to the existing hardware, and relatively minor software modifications.

It is available in a Pb-free, 28-pin SO package, and operates over the -40C to +85C extended temperature range.

Pricing starts at 88 cents for quantities of 1000-up, FOB USA. An evaluation kit is in development as well.
