The DS8113 is a low-power, low-cost, smart card interface. This device performs level translation between a host microcontroller and a 5-, 3-, or 1.8-V smart card, while supplying up to 80 mA for smart card operation. The DS8113 features the industry’s lowest power stop mode, which allows applications to support smart card communication and draw only 10 nA while the card is inactive. Additionally, it provides ±8-kV ESD protection, thus protecting applications from damage during card insertion and removal. Designed to meet all ISO 7816, EMV(TM), and GSM 11.11 specifications, this robust smart card interface is ideal for financial terminals, set-top boxes, and other smart card reader applications.

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° to 85°C extended temperature range.
