Smart-card interface features low-power operation

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

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

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. Available in a lead-free, 28-pin SO package, the DS8113 operates over the –40 °C to +85 °C extended temperature range.
