Maxim Integrated Products introduces the DS8313, a low-power, low-cost, smart-card interface. This device performs level translation between a host microcontroller and a 5V, 3V, or 1.8V smart card, while providing up to 80mA for smart-card operation. The DS8313 features a power stop mode with 10nA, typ, allowing applications to support smart-card communication. In addition, it provides ±8kV ESD protection (IEC) to prevent damage to the application during card insertion and removal. Designed for ISO 7816 and B-CAS applications, the DS8313 is dedicated for pay/premium television, financial terminals, consumer set-top boxes, SIM card readers, and smart-card reader products.

The DS8313 is functionally compatible with devices such as the TDA8024 and the ST8024 that have higher power consumption and no stop mode. It supports applications that do not require communication with the C4 and C8 smart-card pins. The DS8313 operates over the -40°C to +85°C extended temperature range and is available in lead-free 28-pin SO and TSSOP packages. Prices start at $0.60 (1000-up, FOB USA). An evaluation kit is currently in development.
