Smart-Card Interface Offers 10nA (typ) Stop-Mode Current
Note to Editor:
- The DS8023 is a low-cost, smart-card interface IC for use in financial terminals, consumer set-top boxes, and other smart-card reader products.
- This device features the industry's lowest stop-mode current, significantly reducing the amount of current consumed by the application.
- The DS8023 provides a robust communication interface that translates I/O signals to smart-card levels and protects the system microcontroller from ESD events associated with card insertion and removal.
- The DS8023 is designed to meet EMV™ Level 1 requirements for smart-card communication.

SUNNYVALE, CA—April 9, 2009—Maxim Integrated Products (NASDAQ: MXIM) introduces the DS8023, a low-power, low-cost, single smart-card interface. A complete interface for smart-card communication, this device performs level translation between a host microcontroller and a 5V, 3V, or 1.8V smart card. The DS8023 offers the industry's lowest power stop mode, which reduces current draw to a mere 10nA while the card is inactive. This low-power stop mode can significantly extend battery life in portable applications such as wireless POS terminals. Additionally, it provides ±8kV (min) ESD protection (IEC) to prevent damage to the application during card insertion and removal; it supplies up to 80mA for smart-card operation; and it operates from a single supply. Because it meets ISO 7816 and EMV™ Level 1 specifications, the DS8023 is ideal for financial terminals, consumer set-top boxes, and smart-card reader products.
The DS8023 is designed to be a replacement upgrade for parts with higher power consumption and no stop mode, such as the TDA8024 and the ST8024. Most applications can switch from these parts to the DS8023 with little or no change to their existing hardware; users only need to modify their software if they want to support the low-power stop mode.
The DS8023 is available in a lead-free, 28-pin SO package or 28-pin TSSOP package, and is fully specified over the -40°C to +85°C extended industrial temperature range. Prices start at $0.67 (1000-up, FOB USA).
An evaluation kit will be available soon—contact the factory for availability.
